    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?

    • @robertlkiss
      @robertlkiss  3 года назад +1

      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.

    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!!!!

    • @robertlkiss

    One question. Do you apply perspective for those long shadows? You do not say that explicitly, but I think yes, or?

    • @robertlkiss
      @robertlkiss  4 года назад +6

      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.

    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  4 года назад

      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!

  • @lekcje_rysunku

    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 года назад +2

      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.

    • @anerky
      @anerky 4 года назад +4

      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.

  • @oldcowbb

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.

    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 лет назад +2

      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?

    • @robertlkiss
      @robertlkiss  8 месяцев назад

      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.

    • @robertlkiss
      @robertlkiss  7 месяцев назад

      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.

  • @rooftopdwelr
    @rooftopdwelr 2 года назад +1

    ... 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 года назад

      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

      Which circle near the object do you mean? Do you mean the projected ellipse on the right side of the irregular cube?

    Hey robert! Need some help with how to make shadows to a cylinder kept horizontally?

    • @robertlkiss
      @robertlkiss  3 года назад

      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
      @robertlkiss  4 года назад +1

      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 ...

    • @robertlkiss
      @robertlkiss  4 года назад

      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.

    • @robertlkiss
      @robertlkiss  5 лет назад

      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.
