I’m thinking of doing a smaller video where I respond to your guys’ fantastic comments. Let me know if your interested. Many people have given feedback and ways to improve the performance of my triangle renderer. Let me know if I should go over them in a video. :) Edit: I will do this AFTER the next video
YES also I did comment this but I will say it again Lol I have seen you when you first started and get this video on my recommended also how do you have 2k subs with like 3 videos also remember me when you get a play button and super popular and become the new griff patch
The radius of the inner circle is known as the inradius and has a simple formula: r = K/s where K is the area and s is the semiperimeter (a+b+c)/2 (quoted from wikibooks). If you apply this formula, I think you'll see some performance improvements since the square root won't be needed anymore!
@@Henrix1998 no, the area is pretty simple and cheap to get, if one of the sides is horizontal (it's base * height / 2, it's a rectangle cut in half). Making one of the sides horizontal isn't particularly hard either, if you know what vectors and cross multiplication are
remember 2 things: a - level is not the only thing to render, there are coins, stars, enemies, NPCs, and even the player! b - scratch has something called turbo mode.
@@goomygaming980not sure what you mean by this, Turbo mode’s purpose is removing scratch’s inbuilt delay between each block. So I don’t see what you mean that it effects wait blocks
I remember when pen used to be a default part of scratch and not an extension lol. Seriously though, this is kind of insane. I myself have just started to go into opengl rendering, and you've used math to make a software renderer in scratch. Seriously cool stuff
I made some improvements to your math. The radius of the incenter of a triangle is equal to its area over its semiperimeter (half its perimeter). Its area can be calculated by evaluating |x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)| / 2. Assuming a, b, c are the distance between x2-x3, x1-x3, and x1-x2, in respective order, The semiperimeter is (a + b + c) / 2. Dividing the area and the semiperimeter, both sides are divided by 2 so we take multiply both sides by 2, to get the final form: |x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)| / (a + b + c) Also something you seem to do often is finding the point on a line that's closest to another point, here's how you can do that. Start with the line defined by points p1, p2 and outside point p which you want to find the closest point on the line to define t = p2 - p1 find the value (p dot t) / (t dot t) interpolate between p1 and p2 using that value and you have your closest point :) Sidenote: t dot t is the same as the square of the magnitude of t or t.x² + t.y² Also, in the part where you're moving along the line between the incenter and a point of the triangle by distance r0, you can get around the problem of vertical lines by doing this: incenter + normalize(point - incenter) * r0, where normalize means giving a vector a magnitude of 1 by dividing by its own magnitude.

I like your work, but I feel you make your music too loud. I can't really hear your explanations that well. Ignoring that though, that's Insane! Those parts where you showed random triangles with random colors, it looked straight out of an old PZ game. That is SO COOL!
You need to be a math teacher. This isnt even meant to be a math learning video but this SERIOUSLY helped me with my struggle in math. We need teachers like you, make the class have one common goal (in this case, making sm64 in scratch) and guiding the class through it while asking questions. Thats the supreme way of teaching
man i love when you get some basic, unconventional logic system, like minecraft redstone or scratch, and apply complex, low-level mathematics to achieve something 'simple' really makes you appreciate the genius on which our normal everyday programs are built upon
Dude that is fricking insane! I would’ve proudly uploaded a triangle renderer project if I came up with this, but this is just your starting point!!! All the luck in the world for your project!
This seems like it's gonna be an awesome project! I think the 3D engine programming will take you a lot longer than it took to make this video though (ESPECIALLY in Scratch), and I imagine you're gonna have to do an insane amount of optimizing the code. One thing it looks like you overlooked is that you won't actually need to render 1000 triangles at once, because you likely won't be rendering the whole level at once, only the parts you can see.
@@Randmguy48 This is definitely going to be important to remember. Especially when getting into camera programming, as even in original N64 games, anything off camera isn’t rendered. You’re going to need every trick there is.
This reminds me *so much* of when I was first figuring out 3D rendering when I was younger! It's pretty satisfying to figure out the math yourself and get the triangles on screen and (eventually) rotating around in 3D, even if it's not making full use of all the fancy GPU hardware that's built into every device these days. It also gives you a much greater understanding and appreciation for the hardware accelerated APIs if you ever do use them. I recall distinctly feeling like using OpenGL was "cheating" when I first learned it, because it handled so much of the triangle math for you! 😁 Best of luck! There's some serious challenges ahead but I feel like you're well equipped to tackle them!
9:35 you seem smart so I do wonder why they didn't teach you this in high school, cause this was definitely part of my final exam. Great video man I was thoroughly entertained.
Super cool project idea! I'm not much into Scratch anymore, but I was a huge fan of it back in 2009-2013ish. Its quite nostalgic to see that people are still trying to push the bounds of what Scratch can do. A suggestion that might help in the long run: check out vector operations like the dot product. You can avoid all of these if statements to check verticality using vector math instead. Also, its valuable to have a good idea of what kind of code is fast or slow. The best way to do this is benchmark your code, but as a rule of thumb: drawing is snail's pace, if statements are very slow, square roots and division are pretty slow, multiplication and addition are very fast. If you wanna find out why that's true, I recommend getting a computer science degree, or doing a LOT of googling ;P Good luck fam
Cool video. I was pretty shocked in the end, didn't expect a guy with the face of a female supermodel. Hope this isn't rude, you got a nice face and damn beautiful hair.
As someone who has *tried* making a Triangle based 3D Engine, I will tell you that the main problem I encountered and what eventually caused me to cancel the project was depth sorting the triangles
This is so amazing! I love the way how you optimize. I would've never found such a way to optimize it. Amazing content, keep going. I am already excited to se more! 👀👀
It is a pretty smart aproach to rendering triangles but I do want to note that with this aproach you wont be able to render texured triangles, only flat coloured ones. Secondly using this method, lighting can only be calculated on a triangle basis, so there wont be any smooth edges. For specific models in sm64 lighting would be calculated on vertices by vertices basis which then would be interpolated across the entire triangle on a pixel by pixel basis which is very usefull to hide lowpolyness that these old models had. This is called Gouraud shading (heres a great video explaining the concept of it pretty well ruclips.net/video/PMgjVJogIbc/видео.htmlsi=KdT7_uv1Vj04T5KQ). Again this is not achievable using your method. But its still up to you if take your aproach and safe a lot of performance or use the original one and get closer to the original look. (Sorry for bad english)
I think you should be using vectors instead. To move along a line, you subtract the start from the end, and you normalize it, multiply it by the unit length, and then add it to a point.
Awesome video! I'm very excited to watch the rest of this series. Also, here's the way I took to draw the triangles in my project that supports textures, but it is much slower. You can loop through every pixel in the triangle and decide whether that pixel is in the triangle so you can draw it or it's outside of the triangle and you should skip to the next one. To figure that out, you can calculate the area of the triangles ABC, PAB, PBC and PAC (A, B and C being the triangle points and P the pixel you're trying to figure out if it's in the triangle) using the formula ((a.x * b.y) + (b.x * c.y) + (c.x * a.y)) - ((a.y * b.x) + (b.y * c.x) + (c.y * a.x)) (I hope I typed it right) and if PAB + PBC + PAC > ABC then the pixel is outside otherwise it's inside. Lastly, when comparing distances, you don't need to calculate the square roots on both sides, for example instead of it being sqrt(x1 * x1 + y1 * y1) > sqrt(x2 * x2 + y1 * y1), it can just be (x1 * x1 + y1 * y1) > (x2 * x2 + y2 * y2). That'll make it a little faster. I hope you enjoy these tips!
Thank you! As you said, your method is much slower for higher resolutions. I may go back to triangles in the future to figure out textures but for now I’m leaving them untextured.Your comment about square roots is super helpful though! I will definitely go in to change that.
This is great! thanks for making it approachable while packed with knowledge!! my young nephew is starting to learn scratch, thinking i might show him your videos!! (also appreciate you keeping it clean for that reason =] )
2:35 You can set the pen color with 3 parameters, you can even do 4 if you'd like. The way to do it is by settings 3 or 4 parameters of: R - red G - green B - blue A - alpha (transparency) (these all have to be set between 0 - 255) You can use these parameters to change the pen color by using this method: Set pen color to = A * 16777216 + R * 65536 + G * 256 + B Note that the "set pen color" has to be the one without the drop down menu. I feel like this coloring method will be easier to use if you eventually add a simple lighting system and it also makes it a little more user friendly. Hope this helps!
I find it funny that you use desmos (a graphing calculator) to figure out math equations for scratch, when I use scratch to fivure out equations for my graphing calculator and the c# programming language
Madlad. I have no clue how you're going to do this, I never would have considered doing something insane like this. I wouldn't have known where to start with the triangles, but this is a very elegant solution. I'm surprised that scratch is able to handle this many triangles so well, because I tend to have lots of lag issues in scratch. Good luck making the 3d engine, I hope your computer will be able to handle it :)
Holy shit this video is insane, ever since the first video popped up in my home page I knew this wasn't just a random channel and I've got to say, I'm not disappointed at all! Your videos are amazing and this entire project is fascinating to watch. Looking forward for the next video in the series, keep up the good work man!!!
This is a great video and im looking forward to this series, my only criticism is that your music is very loud at some parts but otherwise it was very well made.
I don't want to know the amount of work that this video would have taken to produce. I would have given up halfway through if I were you. I admire your determination and you have considerably impressed me with this video!
When you made the intro video I was like, no way blud can make Mario 64 in scratch, but the moment that it was revealed that your a math prodigy I was like, ok this is going to be interesting.
You just saved a problem I had with the fps when trying to make a 3d game! That’s impressive! Do you have a discord server? I’m in a discord with a other game developers and I impressed them with what I have built in scratch, but you just impressed me!
I think this should be a world record for most complex way to rasterize a triangle. This is what software engineering is all about. Finding unique ways to solve problems that have very weird and specific restrictions.
@@OKF. well if we're talking about doing it in Scratch, this video would probably be it. Otherwise, there are a ton of methods you could use. I'm not experienced enough to point to one in particular as the best though.
Boy, you're videos are really great, but I have to say that at 1.3x the speed it is 5x better. So I suggest you to do something about that! Also your volume is a bit low and I am sure that makes a lot of people click off instead of turning their volume up...
...Hes never coming back, the triangles got him. 😭😭 The polygons were too much. (after you SOMEHOW have success with this project, you should try making Sunshine in scratch (this will never happen)).
Hey man, I just wanted to say I’m a developer with nearly 25 years industry experience now and I freaking loved this video. It reminded me of first learning to code in QBasic and writing my own crappy wireframe 3d graphics engine while in high school. I love that you are writing yours in scratch, working out optimisations for the most basic of primitives, and showing your math - really cool stuff. This was an excellent video and I look forward to following your progress! No pressure though, life is hectic!
As a BS in CS who gave up near the end of his Minor in Math, I completely understood this video even though I didn't want to and now want to defenestrate myself. Oh, but really cool video btw, take my sub! Looking forward to the next painful video.
Just a small suggestion. When making these videos. Make sure the music is about half the volume of the narration. Because when I listen to you talking I can hear the music overcomes your voice a lot and it distracts from what you are trying to explain
You should add an option to allow people to fill in less of the triangle if they want better performance. Also you might run into some issues when you make billboard sprites because sometimes they're supposed to render under 3D geometry, which you can't do with the pen tool in scratch
Your idea about performance is actually very good, thank you! I may come back to triangles in the future but right now I have no idea how to make textures work efficiently.
@@Randmguy48 yeah, that's another thing I was thinking about. Given how low res the textures are though, you might be able to just... Not have them at all
@@kimgkomg Yeah, but pen lines in Scratch render under all sprites. So that would only work for the billboards, but all the billboards would render over all the polygons
@@ZaaryJust because you're little doesn't mean you can't do research to the point that you are better than most adults at it. Practicing make you better and you shouldn't be criticized for age about your job.
I've done some experimentation with trying to make a 3-d engine in scratch and have always had this same problem of "filling in the triangles is too slow", so I've just used either very simple geometry or wireframe models. Glad you've figured out a good way of solving this issue
i love it when ppl get overly ambitious and use highly sophisticated math concepts for a stupid project, this is the type of content i love, keep going at it man
Dont give up on this man, i beg of you. ive been waiting for someone to do this since ive joined scratch as well. we all believe in you. you can do it!!!
This is so awesome! Hope all goes well with the Super Mario 64 in Scratch Project and the Scriptwriting, Artwork, and Editing for these RUclips Videos. Have fun and relax because both are really cool to see. You're doing great!
I am so incredibly impressed by your dedication and skill! I was 25 years old when I realized that math is important for everything that is fun. I hope to see many more amazing videos from you, no pressure though! Remember to take time for yourself. ☺️
that is INSANE [positive] i did some simple programming in scratch in elementary school, the teacher in compsci class wanted us to recreate a specific simple game, and of course she did not want us to figure that out based on some info, she told us the specific steps we should take because she is evil. and i was a naughty brat and after a few minutes of following the steps i just started working on my own, then i had to backtrack to figure out what i did wrong cuz some stuff did not work even remotely right what kind of lunatic teaches kids to program by spoonfeeding them code they need. if she told us some basic stuff and told us to mess around and maybe ask for help, the vast majority of the class would learn so much more.

wait, its an extension now? also scratch looks different from what i remember
@@blabbilizer
Scratch released 3.0 and changed them from the smaller blocks to bug thicker blocks if thats what you see
I made some improvements to your math.
The radius of the incenter of a triangle is equal to its area over its semiperimeter (half its perimeter).
Its area can be calculated by evaluating |x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)| / 2.
Assuming a, b, c are the distance between x2-x3, x1-x3, and x1-x2, in respective order,
The semiperimeter is (a + b + c) / 2.
Dividing the area and the semiperimeter, both sides are divided by 2 so we take multiply both sides by 2, to get the final form:
|x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)| / (a + b + c)
Also something you seem to do often is finding the point on a line that's closest to another point, here's how you can do that.
Start with the line defined by points p1, p2 and outside point p which you want to find the closest point on the line to
define t = p2 - p1
find the value (p dot t) / (t dot t)
interpolate between p1 and p2 using that value and you have your closest point :)
Sidenote: t dot t is the same as the square of the magnitude of t or t.x² + t.y²
Also, in the part where you're moving along the line between the incenter and a point of the triangle by distance r0, you can get around the problem of vertical lines by doing this:
incenter + normalize(point - incenter) * r0, where normalize means giving a vector a magnitude of 1 by dividing by its own magnitude.

Set pen color to = A * 16777216 + R * 65536 + G * 256 + B
Note that the "set pen color" has to be the one without the drop down menu.
I feel like this coloring method will be easier to use if you eventually add a simple lighting system and it also makes it a little more user friendly.
Hope this helps!
I find it funny that you use desmos (a graphing calculator) to figure out math equations for scratch, when I use scratch to fivure out equations for my graphing calculator and the c# programming language
Madlad. I have no clue how you're going to do this, I never would have considered doing something insane like this. I wouldn't have known where to start with the triangles, but this is a very elegant solution. I'm surprised that scratch is able to handle this many triangles so well, because I tend to have lots of lag issues in scratch. Good luck making the 3d engine, I hope your computer will be able to handle it :)
Thank you!

Holy shit this video is insane, ever since the first video popped up in my home page I knew this wasn't just a random channel and I've got to say, I'm not disappointed at all! Your videos are amazing and this entire project is fascinating to watch. Looking forward for the next video in the series, keep up the good work man!!!
Thanks!!
This is a great video and im looking forward to this series, my only criticism is that your music is very loud at some parts but otherwise it was very well made.
legends say he's still making a 2nd triangle
actually im making a 3d triangle 👀🤯
@@Randmguy48 NO WAY

We want you to complete this serie as fast as possible, because we're enjoying it so much! KEEP GOING!!! 💪💪💪🔥🔥🔥
Off topic but your hair is majestic
Thank you
Underrated.. like your scratch projects!

i love stealing jokes from other people
I don't want to know the amount of work that this video would have taken to produce. I would have given up halfway through if I were you.
I admire your determination and you have considerably impressed me with this video!
this is a greater and more drawn-out tragedy than even shakespear could come up with
drawn-out tragedy
Shakespear probably couldn't even write his own game engine in C 🥱
When you made the intro video I was like, no way blud can make Mario 64 in scratch, but the moment that it was revealed that your a math prodigy I was like, ok this is going to be interesting.
You just saved a problem I had with the fps when trying to make a 3d game! That’s impressive! Do you have a discord server? I’m in a discord with a other game developers and I impressed them with what I have built in scratch, but you just impressed me!
I don't have a Discord server but I am thinking of making one if enough people request it!
I think this should be a world record for most complex way to rasterize a triangle.
This is what software engineering is all about. Finding unique ways to solve problems that have very weird and specific restrictions.
What would be the easiest or fastest way to rasterize?
And how would I go about learning it
@@OKF. well if we're talking about doing it in Scratch, this video would probably be it.
Otherwise, there are a ton of methods you could use. I'm not experienced enough to point to one in particular as the best though.
Great video!
Of course that's a great video! He put a lot of effort!
Boy, you're videos are really great, but I have to say that at 1.3x the speed it is 5x better. So I suggest you to do something about that! Also your volume is a bit low and I am sure that makes a lot of people click off instead of turning their volume up...
...Hes never coming back, the triangles got him. 😭😭
The polygons were too much. (after you SOMEHOW have success with this project, you should try making Sunshine in scratch (this will never happen)).
that would be an action packed blockbuster film
Hey man, I just wanted to say I’m a developer with nearly 25 years industry experience now and I freaking loved this video. It reminded me of first learning to code in QBasic and writing my own crappy wireframe 3d graphics engine while in high school. I love that you are writing yours in scratch, working out optimisations for the most basic of primitives, and showing your math - really cool stuff. This was an excellent video and I look forward to following your progress! No pressure though, life is hectic!
and then he was never seen again..
yeah :(
hes awesome at this tho
Can't wait for the next vid bro! amazing work
this is what the teacher means by "you will need to know the pythagorean theorem later in you life"
this is EXTREMELY impressive for scratch, congratulations for this amazing achievement.
pls part 2 its been a year
He said he's planning to release it this month
@@edemaiscomtheovieira2718he hasn’t done it yet :/
its gonna take a bit, especially since scratch is pretty limited
As a BS in CS who gave up near the end of his Minor in Math, I completely understood this video even though I didn't want to and now want to defenestrate myself.
Oh, but really cool video btw, take my sub! Looking forward to the next painful video.
I’m sure this is a great video, but I _cannot_ hear him above the music
this is the best content ive seen in a while. youre awesome!
Just a small suggestion. When making these videos. Make sure the music is about half the volume of the narration. Because when I listen to you talking I can hear the music overcomes your voice a lot and it distracts from what you are trying to explain
Good to know. Thanks!
this is gonna be legendary, holy hell
good luck!
After i watched this video i sent it to my algebra teacher to see her reaction.
What he said?
@@mekaindo she was completely stumped and didnt understand anything
@@BTDlegand101 lmao
@@mekaindo yeah. i cant wait for Randomguy48 to remember he still has to add the 4th side to each triangle!
It’s almost like I can still hear his voice. Fly high, Randmguy48 🕊 ❤️
Did you check the community post?
This guy is underrated.
i really enjoyed this, i understand that making these takes a long time, but we have been waiting longer than we waited for this episode to come out!
You should add an option to allow people to fill in less of the triangle if they want better performance. Also you might run into some issues when you make billboard sprites because sometimes they're supposed to render under 3D geometry, which you can't do with the pen tool in scratch
Your idea about performance is actually very good, thank you! I may come back to triangles in the future but right now I have no idea how to make textures work efficiently.
@@Randmguy48 yeah, that's another thing I was thinking about. Given how low res the textures are though, you might be able to just... Not have them at all
He could just give each billboarded sprite a priority no? I'm pretty sure the real sm64 does that
@@kimgkomg Yeah, but pen lines in Scratch render under all sprites. So that would only work for the billboards, but all the billboards would render over all the polygons
@@owencmyk can't you stamp the sprites then and then hide it
BROOOOOO, your idea that you make SM64 in scratch, is awesome! KEEP UP THE GOOD WORD BRO
As a games developer, this hurts my soul in every single possible way and I love it
ur probably like 15 year old, not a game developer
@@Zaary oh yes because people need to be 90 years old to be considere game developers
@@ZaaryAge doesn’t really matter that much here
@@TotalDramaHarold it does, with age comes experience, and in gamedev without lots of experience you are a really bad at it
@@ZaaryJust because you're little doesn't mean you can't do research to the point that you are better than most adults at it. Practicing make you better and you shouldn't be criticized for age about your job.
I've done some experimentation with trying to make a 3-d engine in scratch and have always had this same problem of "filling in the triangles is too slow", so I've just used either very simple geometry or wireframe models. Glad you've figured out a good way of solving this issue
Where is the next video?
This is fantastic work! I am so excited to see what is coming up next.
Me: still waiting for part 2 for almost 1 jear...
i love it when ppl get overly ambitious and use highly sophisticated math concepts for a stupid project, this is the type of content i love, keep going at it man
Is there any Discord or anything we can join? Would add the community to it, who could give you nice ideas ;)
There isn't right now but if enough people really want it I could make one.
The rendering of the triangle was interesting, but even more shocking was how beautiful you look
I hope that this all goes well
i am going to subscribe, and turn on notifications ready to follow this series!!
also,good luck with school and marching band!
wow you made a trinagle
Dont give up on this man, i beg of you. ive been waiting for someone to do this since ive joined scratch as well. we all believe in you. you can do it!!!
Bro cooked and then dropped out
This is so awesome! Hope all goes well with the Super Mario 64 in Scratch Project and the Scriptwriting, Artwork, and Editing for these RUclips Videos. Have fun and relax because both are really cool to see. You're doing great!
I HOPE IT GOES WELL
I am so incredibly impressed by your dedication and skill! I was 25 years old when I realized that math is important for everything that is fun.
I hope to see many more amazing videos from you, no pressure though! Remember to take time for yourself. ☺️
Bro are you going to upload
Can't wait to see him creating the first 2 poligons! It will be incredible and unique!
Bro is smarter than griffpatch 😯
i wouldn't have thought something like mario 64 in scatch would be ever possible, great work!
that is INSANE [positive]
i did some simple programming in scratch in elementary school, the teacher in compsci class wanted us to recreate a specific simple game, and of course she did not want us to figure that out based on some info, she told us the specific steps we should take because she is evil. and i was a naughty brat and after a few minutes of following the steps i just started working on my own, then i had to backtrack to figure out what i did wrong cuz some stuff did not work even remotely right
what kind of lunatic teaches kids to program by spoonfeeding them code they need. if she told us some basic stuff and told us to mess around and maybe ask for help, the vast majority of the class would learn so much more.
Great video man, I was entertained the entire time. You also have no idea how happy it makes me that you’re in marching
guys… how he gonna do a triangle 3d engine
Math
Bro I thought someone with like a million subs would have made this. You are so underrated great job 👍
