I dont know if someone noticed, but the position of the Vanishing point (more hight or low) will determine the position of the Light souce in relation to the object (if the cast will be in front or back, for example). Change the SVP position and try to imagine this image from bird view
@Urserer I could work on that! If the shadow is hitting a vertical surface (wall, etc) it will change direction and be vertical, if it's hitting an angled surface, it will change direction to that angle. That's a really basic short answer. :)
It's where you position the shadow vanishing point (SVP...on ground), With the light being on the left side, if you position the SVP horizon to the front (nearest to you) left of the corner dot of the ground plane, the light will hit directly sideways to the object, on the front. If you position the SVP to the back (furthest from you) left (the dot furthest away), the light will hit sideways on the back of the object, creating the shadow to be slightly in front. Now, if you position the SVP to the middle of those dots, the shadow will be directly sideways of the object. The SVP does NOT determine where the ground is, it determines the position of the light. The lower the SVP is, the more front the light will be, the higher, the more back the light will be. really, the shadow vanishing point doesn't have to be exactly vertical with the light, you can position it anywhere. It's a give or take on that last part, I would just draw some examples and experiment, that's actually what I've been doing, as I, too, just learned about shadows on floating objects.
Cool stuf, how about more complex stuff like inverted piramid casting shadow on a cube, and cube casting shadow on a sphere all in one scene and elevated ? And alao how does shadow behaves best the surface it is on changes shaoe from flat to like 90 deg. droo etc
These videos are great! I was wondering though, would you be able to to another cast shadow video, but one that covers when the shadow hits other objects? I'm running into a problem with my current perspective drawing where a balcony is casting a shadow partially onto the building and into an alleyway, but I can't figure out the process.
thanks so much for this video! you have no idea how much it helped on my math essay. but is it okay if you can upload a video showing a "disc" shape or a cylinder instead of a rectangular prism for shadow casting? thank you so much!
@sloshbg She definitely did a good job! So hard trying to find decent perspective tutorials on youtube. Comprehensive, clear and straight forward. Thanks for the upload! =]
Best tutorial I've seen. Thank you
Struggled with this yesterday with what I now see was an incomplete explanation. Huge thank you, explaining which lines cross which lines.

1:59, How do you know that the ground is there?

How do you determine how far down the shadow vanishing point should be?
Great explanation! Super helpful!

I was wondering what program are you using for this video. I feel you did a great job explaining this subject
Your video was great. Thanks A LOT
Hi, do you think I could have access to a tutorial for perspective cast shadows on a floating object, being it a cylinder?
thanks so much for this video! you have no idea how much it helped on my math essay.
but is it okay if you can upload a video showing a "disc" shape or a cylinder instead of a rectangular prism for shadow casting? thank you so much!
how do you determine the shadow vanishing points exact location? it seems like it depends on the height of the observer wrt the ground plane
Why would the shadow guideline not be on the vanishing point line?

Thank you.
Thanks
@AndrevwZA
Definitely check out my basic cast shadows tutorial on my page. :)
good good
What problem do you use btw?
Easy to understand than my math teacher
