Hello from Hong Kong, I learn drawing since I was a boy, I went to many drawing classes but NO one teaches me how to draw correct shadows as you do. Thank you.
HI Robert I am really lucky to found your excellent courses. You are a really good guy because sharing your experience and knowledge. Never stop your work please. Thank you.
Hey from Brazil, im applying for a design college here and i wanted to learn how to draw well before it, u are helping me a lot, thanks for the support !
Agradeço por produzir e disponibilizar esses vídeos de perspectiva, eles ajudam bastante, afinal esse fundamento é bem difícil de se dominar e cabe o estudante procurar ajuda, você faz um bom trabalho.
You carry so much knowledge Mr. Robert thank you for always sharing them, happy to have found your channel, drawing was made much easier, God bless you, sir.
hello from philippines, i love arts, i start to draw digital im am not confident with my sketching skill in papers and pen. I love how you teach to determine the shadows and highlights. Now I'm becoming an industrial design student,, thank you for your videos. I learn a lot.
Thanks, i'm glad you enjoy these. I will definitely come back with more tricks and tips later on, but for now these were the main topics I wanted to talk about so there will be a switch in the type of videos.
by far the clearest post on this issue ( I just watched 10 others) - but some use the idea of a Shadow Vanishing Point and place this on the horizon line - is this a different approach?
No that is correct I use that same technique here I just didn't mention it particularly because i thought it's self evident. The lines of the shadows that are not derived from the shadow direction are all parallels with the originating object which goes to the vanishing point.
Amazing video, very helpful! Have you made a video, where you explain the cast shadow of a sphere with a point light, rather than parallel light? If not, I would be so great full if you made one! :)
May I ask, why do we have to bring the ellipse down to the ground level at 10:20? Why isn't it (correct) enough to cast the shadows from where it stands on the box, at that level? Is it simply an alternative to casting the shadow on the top plane of box, then going down the side of the box (straight line) and then moving on to where the Light Direction signaled as the end of the cast shadow? AMAZING videos by the way, thank you!!!!
What I miss here is casting a shadow on the floor and then - wall. Its easy as it seems, but I have failed to draw a table in a room with perfectly drawn shadow.
That is a good question. If they are quite long then yes it makes sense to apply perspective to them. But in general for Product Design sketches we let the shadow fade away because it is not useful information.
Thank you so much. Your videos are very helpfull. Do you know how to draw helicoïdal (in spiral) stairs with the clock method? i'm looking for that since a long time..
Drop shadow is a blindspot I didn't know I had :D What happens when the object is above the horizon line ie tall building (considering LS is the sun above it)
Hello Robert. Is it possible to make a video about constructing a tube in perspective, that is “swinging”? The problem with that is how to construct the ellipses. Thanks.
Hey Robert, I think I already constructed a tube in perspective. It is a bit different when you talking about objects in motion. If we are talking about a swinging object the easiest way would be to construct it at the two extreme points of the swing and once in the middle, from there you would have to construct it 2 or 3 more time approximating the in-between states. Interesting suggestion though, let me think about how to incorporate movement constructions into a future video!
Szia! Nagyon tetszenek a videóid! A henger árnyékának szerkesztésénél viszont nem tudom hova tenni azt a részt, amikor a cap-et újrakonstruktálod a vetett árnyék "végénél". 3d-s progiban is meg szoktam nézni a dolgokat és semmilyen módon nem bírtam előcsalni a szitut, amikor a két elipszis közel azonos szögben van. Tudsz esetleg segíteni a dolog megértésében? Nagyon várom a válaszodat, köszi előre is! :)
Hey I have a question. When to draw shadow direction lines parallel to each other and when to project the sun on the horizon and draw a converging shadow?
Shadow lines never converge, they only diverge. Usually during day scenes you have parallel lines because the sun is so far away that the converging angle is negligible. Whenever you have direct light sources then the shadow lines are not parallel because of the converging nature of the light beams
copying ellipses ... pfff really nice i found this channel. Does this technique also work for more organic forms or with two light sources ? Like how you explain it by the way.
if you can draw a single stick in any given lighting situation, then you can draw any form in any given lighting situation, since you can create any organic shape through the close packing of infinitely many sticks of various lengths. If I was trying to do a shadow for a shape that was too complex to feel comfortable drawing outright, I would approximate it by sticks and get a feel for how its shadow will be... many sticks' shadows will be contained within the boundary of the shadow overall, so you can become more efficient once you develop an intuition.
@@robertlkiss ok so this was really good it's what I have been looking for. So just me talking here, so I'm 41 and really learning to draw , really learning. It's hard getting information, sometimes it's to dry , and or not informative enough. But I find the big problem to be here is that , very talented skilled people that have been doing it along time forget that we don't know shit. This was really informative. Idk if u already have it . But I would enjoy a run threw video, a prep vid of a fast moving this is we're you start these are the steps you take , a game plan lay out , then vids breaking down the steps , and maybe a few extra detailing the little extraa and tips . That was you see a plan , see it step by step , then see the tricks . This would make q full picture. And it would allow a foot hold for every vid you already have.
It would be easier to explain this via video so I might do one on this topic in the future. But for now: In general, if the sun is high in the sky u get the shadow below the object. So just as with a cube, the shadow would be exactly below it. If you want to construct a cast shadow simplify the tree. Think of it as a sphere on a cylinder (almost like a lollypop). And then you can use the same projection exercises I showed in the video. I hope this answer helps somewhat :)
Why do you keep the ellipse the same when drawing the shadow? Would there be any instances possibly outside of industrial design where you don’t do this maybe a long shadow where you want to indicate perspective?
The ellipse is technically not the same. The correct ellipse size is always between the one that touches the ground and a flat line that is on the horizon depending on where the light source is coming from and how long it is. But it will be relatively too size of the bottom ellipse especially. What changes is the length of how far this ellipse gets projected from the object which it belongs to.
Because colored shapes are so varied we tend to teach the basics of projection and from there you will have to figure it out yourself. Basically everything you learn in this video should allow you to cast whado s on more complex shapes as well.
... I'm having a hard time understanding why the LD angles are being drawn in parallel to each other when the light is coming from ONE light-source. Since it is a single-source light, shouldn't the light direction angles all be emanating from the single point at which the light is located... tapering out and NOT in parallel. Logically, if the LD's are drawn parallel (like how you are doing in your video), wouldn't that only make sense if EACH vertices had a corresponding light source?
You are correct. However the light source is usually the s un. On the paper I drew it that close as a representation of the direction. But if the light comes from such a far distance it can be drawn as parallel since the angle is undetectable.
10:18 i got lost , what exactly made you draw the circle near the object and how did that translate to finding where the shadow is gonna be positioned, which part of the vid or videos do i have to revisit to figure this one out
Just create the shadow of the section plane(middle plane) of the cylinder that is perpendicular to the ground and round the two shorter sides, that the simplest cheating way :)
@@robertlkiss I could say that as you have the same accent as some of my friends from Holland. Best of luck and thanks again. I am going through every lesson you have. They are the best
Sorry but there is no real formula. If you draw from nature you look at the shadow direction itself otherwise you have to set up the initial direction and follow that one with all the others you draw.
Shadows seems to make the same angle with any 3d shape you draw. It's that a rule in industrial design? I've found a video about cast shadow in perspective and it doesn't look like that ...
I used the same angle because I used the sun as light source and at that distance the light rays can be considered parallel. But if you wanna use a lamp or any closer light source then yes the light angles will differ. Was this your question?
Not sure I understand your question. Objects in sunlight only heave one shadow direction. Only when they are hit by several lighter sources do they have several shadows like football players.
@@robertlkiss My real question is: If only one corner of a cube, instead of an entire side, touches the ground, how to set up the shadow direction, the light direction and the point where they intersect?
Pedro João you mean if a cube is balancing one one corner? Wherein e a rth do you see that in nature?:)) think of it as an upside down cone or pyramid mid.
@@robertlkiss Yes, that's exactly what I meant. I'm aware there's no such a thing in the real world, it's because I'm thinking about how to cast shadows in extreme situations such as the cube standing on only one corner, or an inverted cone.
@@pedrojoao2941 as I said just do the shadow for an upside down cone. You saw how to construct shadows for cones and for cylinders it's the same exact process.
It's what I'm talking about at 7:01 basically you have to take the ellipse from the top and reconstruct or copy it to where the light direction takes it on the ground. Think of it like this if you hold an umbrella in the sunlight, the shadow will form a very similar shape to the round umbrella. That is with we are doing with these constructions. I hope this helps.

do you most often assume infinitely far away light source? because you use parallel light direction for all point on an object
Good questions. Usually, I use the sun which is not infinitely far away but for our purpose, the sun rays might as well be parallel.
How to estimate the light distance, how to find this point on the ground?
you dont have to estimate the light distance, you just intersect the light and shadow directions.
