Hi everyone! Glad to hear you're enjoying the video, it means a lot. I added the source code in the description for those who asked (it's kind of a mess). My semester just ended so I should have some time to work on another graphics project. Let me know what you guys wanna see below! - Cheers
heyy, i really enjoyed your video about computer graphics. Im currently researching sources for my Bachelor Thesis from computer graphics and i would like to ask you, if you could share some insights on how you research topics. It would be really helpful, couse i have no idea where to find sources and mainly what to search for.
@@simonzanta1403 Public code repositories were certainly my best friend during this project! If I ever needed inspiration for some feature or felt myself getting stuck, I would do a quick search on RUclips or Google for something similar and that was usually enough to get me through. Another tip is to try breaking down your research into smaller pieces that will be easier to source (ie. "OpenGL instance rendering" as opposed to "OpenGL particles"). Hope that helps!
hello there, really liked your video! I'm a first year computer science student, I would like to know more about what you do and how you got here, I'd love if you'd upload a video talking about yourself, your work and your journey, it would really help and inspire me! Thank you for this great video!
i love the work, why dont u make gravity simulation using nueton's thurd law of motion, i tryied to do it in unity, it kinda works but somehow the particles after attracting to each other and colliding they start to repeal each other (using barn's hut algorithm , no error in my code) , maybe u can do a simulation and explain the optimization method u choose.
hello pezzza i adore your videos. I am in highschool and want to make cool physics simulations and fractal stuff. I know some c++ but struggle with implementing stuff like this. How do you recommend i learn to build real, actual projects?
I have studied physics in 1991-1995, and I had a semester on Fortran in the university. Then at 2004 I learned a little C, and the following years I was slowly reading a few books on C and C++ (mainly I was reading stuff about networks and linux for my jobs) . Since late 2023 I became a junior C++ developer. A few weeks I started learning OpenGL (I can give suggestions to who ever is interested). But I know that I am nowhere near the level to make such simulations! I am so impressed that you are still a university student and can produce those videos!
i was thinking about to implement opengl into my little javascript particle system (JPS on github) but during that i came across webgpu and i think thats the better choice. but its hard, shader scripting is another level of abstraction...
This is super impressive! Casually glossing over the fact that you taught yourself *not just C* but also how to render things with openGL is no small feat. Your in-depth knowledge of particle simulation is also pretty impressive, requiring at the very least knowledge of relatively advanced calculus and physics. And, on top of all of that, this video was very well written and edited. Overall great job, keep it up!
Ever since contracting brain rot due to working the most boring job I could imagine, this is the first video in 2 years that I didn't skip, fastforward, etc. Bravo dude. Gees.
hello. i am a beginner in all those things and have just found this channel....can't say how grateful I am to you. You, my friend, are an inspiration. You are Knowledge. You are Greatness. You hold the Power. Thank you so much. Thanks. Would like to see more of these simluations, math-physics-chemistry-related programs and such. Thank you.
this is amazing. i love how you have combined the most notorious subjects like physics and linear algebra and combined them into an amazing program, all in c! absolutely wonderful quality.
This is a great video, and it is surprisingly well edited! I am not interested at all in physics simulation but the way you explained it really made me start paying attention and it was interesting how you used each optimisation technique to achieve even better results!
this is a great video mate. this video remainds me of sabastian lague's videos. when ever i have thoughts about why i chose programming as a career i think of these kind of videos which boost my happiness and i say to myself that this is why i chose programming as a career to build cool stuffs. thanks mate. Great job !!
Very nice video ! You might want to also look at fluid simulation using particle called Smoothed Particle Hydrodynamics. Basically you replace the collision algorithm with a constraint on the density modulated by a kernel. It sound bad like this but you already did 90% of the work there. Keep up the good work ! See you next video.
@@Smiley01987 I didn't talk about job positions, I was talking about programming as a mastery in which you can be capable of much more if you know math.
I have had this as a future project in my mind for years. I never went to third dimension due to the fear of linear algebra. This is really impressive and inspirational. Thanks for sharing.
One more was to implement optimization is to compare the length squared (in handle collision) instead of competing the length. It means you replace a square root call (expensive) with two multiplications (one of the radius is the same), which can even be pre computed once if every sphere has the same radius: x²+y²+z² < 2r²
That was my initial thought as well! The only issue is that to "resolve" the collisions, you still need to push each particle apart by half their separation so you would need to compute the distance regardless. I tried moving the square root function inside that condition but it didn't make too much of a difference :)
@@gr4dience true, haven't thought about the fact that you need the value later. Still interesting though that it makes almost no difference when computed inside the if body. I think that means the grouping into chunks optimization to not check every sphere against every other has a good grid size and already avoids most checks, so most checks have to do the sqrt anyways.
naw bruh you can get this good - its possible for any of us. if u wanna build something like this just fuckin believe in urself dawg u can do it. do that, and videos like this produce nothing but inspiration and excitement for your future work :)
I took a graduate level numerical methods course (my prof contributed to some popular CFD software) and it was very cool to see the different algorithms used. Great job !
This is going to be a fantastic springboard for my own physics sim ideas! Starred, will fork when this makes it to the top of my project queue (it's about number 3 I'd say, but full disclosure, it might also never happen 😛)
Very nicely done! I like that you said what you did and kept it rather high level for the video. Whereas, if needed, and if you haven't already, then you can make a more detailed video for the code and maths. Great paste and keep at it!!
Gradience, this video is absolutely astonishing. Putting aside the great editing and video structure, the flow of your story and the way you tell it is both fascinating, and so intriguing. I adore computer science as a whole, and this is possibly one of my all time favorite videos now. What a masterpiece you've made. Subscribed, and hope to see more of what you do! :)
Dude we have the same story. I spent 2 years building a physic engine because I saw that one video. But mine is in JS. it's terrible. I love it. Great video BTW.

The editing in this video is incredible
You can achieve the same using an open source python library called manim
Super cool video! Always funny to see we all encounter the same bugs along the way :D

me too gonna start college in august so im gonna learn C and make this happen good luck to you too
@@_Rie_Good luck! C is a tough language in the beginning, but it's so satisfying to use once you've conquered the main pitfalls.
How did it go?
me too

Engineers make a small number of good RUclips videos then dip back into the void to do their job. This is the good shit.

I am here with you also a noob
Same here, I've been wanting to implement programming with the sciences. It'll bring hard but we can do it

Someone: "You don't need math to be a programmer"
Yeah, same as you don't need much strength to hold a sledgehammer... but you need it to wield it.
Good metaphor.
Programming is so much more than using complex equations all the time. It all depends in which field you're in.

Channel name + channel banner is literally +1000 aura im gonna steal this
So much of this is reminiscent of physics used in molecular dynamics simulations.

This video is amazing! It reminds me of Sebastian Lague’s video’s.
yea very similar project
That was awesome! My favorite part was when you found the linear algebra text and got your change of basis on.
This is pure art. Amazing work bro.

I literally just stumbled on this video, amazing and very fun to watch. Made want to actually learn C and take a break from JS for while lol
Good luck for your success on yt. We need more content like this.
this video deserves much more than 2.7 k views
Yay another channel with my favourite type of content
Inspiring, makes me want to drop all my JS projects and return to low level.
dang you're a legend if you used a physical Linear Algebra textbook to solve your problems. Subbed!
Now I want to do this by myself.
I clicked because of C!
I just love a good simulation, and even better when it's on C.
When you realise that math class was not just a class
Fantastic good job
This is so cool :) You've inspired me to want to do something similar
so that face pull in Mario 64 is a masterpiece of my childhood.
dude, you're so incredible. I'd like to see more videos. keep doing them :3
really beautiful video . i can now see the importance o mathemetics in programming
I definitely wanna give this a shot if I can save up enough for a laptop
Another awesome programmer I have to subscribe xD
Great work
Absolutely stunning, more videos using C please😮
Now i have another reason to keep studying. You're an inspiration for me :D.
If you are working with grids, the paper "Compact, fast and robust grids for ray tracing" is very worth reading to optimize further
I'll check it out!
nice and simple representation
this video is amazing
it feels like it's been made by a channel with at least a few hundred thousand subs
keep it up !!
