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.

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.

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!!!!

... 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?
@robertlkiss
@robertlkiss 2 жыл бұрын
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.

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?
@robertlkiss
@robertlkiss 2 жыл бұрын
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
@oldcowbb
@oldcowbb 4 жыл бұрын
do you most often assume infinitely far away light source? because you use parallel light direction for all point on an object
@robertlkiss

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.

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?
@robertlkiss
@robertlkiss 5 ай бұрын
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.

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.
@robertlkiss
@robertlkiss 3 жыл бұрын
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!

In nature, how do you determine light direction and shadow direction? How do you draw shadows of trees, for example if the sun is high in the sky?
@robertlkiss
@robertlkiss 5 жыл бұрын
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 :)

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.
@anerky
@anerky 4 жыл бұрын
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.

I dont really understand the copy the same eclipse thing can you explain more details? Thanks

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.

Hey robert! Need some help with how to make shadows to a cylinder kept horizontally?
@robertlkiss
@robertlkiss 3 жыл бұрын
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 :)

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?

What if the object has only one shadow direction? I mean, if only one corner of a cube touches the ground?

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.

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.
