I'm trying to understand perspective shadow. I read the Perspective Made Easy book and it seems straight forward but when I try to do a simple box shadow, it seems odd:
I can't see where I should "end" the shadow length, is the shadow above correct or should the shadow be enclosed within the aqua polygon ?
Also sunlight is apparently "parallel". When I try to draw parallel rays of light, it makes it harder to tell where the shadow should end, is this the correct location?:
Can someone shed some light on this please? (no pun intended lol)
