Nice. Of course this gets infinitely more difficult with complex or organic forms, or objects raised off the ground etc. I think with practice and an understanding of 3d space, one can learn how to quickly lay down a believable shadow.
I assume if you have a floating object you have to project the points down to the ground plane first? kind of like how you project the top plane of the cube in your first demonstration
I'm currently immersing in Scott Robertson's How to Render. It's such a great book but sometimes Scott is not totally exhaustive in his explanations. For example, what if I have a white cube, and I modify the shape to have a long ramp jutting out from the middle of the 3rd face (the darkest face among the 1,2 and 3 read) and angles down to the ground. In this case, the cube casts a shadow over this ramp. Here I don't know how to assign values to the entire set: 1. I assumed that everything inside the cube's shadow would have a base value of 5. Adding reflected light and occlusion shadow made the set believable. 2. I repainted the set again with the assumption that because the ramp angled away from the local light, the shadow falling on it would follow the Half Way To Black rule, and ended up darker than the rest of the 3rd face. The set was somehow also believable to my inexperienced eyes. Could you tell me which scenario was correct? Thank you.
@@EricStrebel can you actually show how to do it, especially surfaces that are not right angled but where the surface changes few times at different a angles than 45 or 90 degrees like 10, 30, 70 etc

I've seen dosens of tutorials about cast shadows lately. Best explanation I've ever seen. Totally underrated.
Thank you 😀 feel free to share on social media that helps me so much to promote the channel
I will certainly be watching this again as it is so helpful. Thanks for sharing it.
Glad it was helpful!
Amazing video, very well explained. I loved the scene you built and the photoshop drawing on top ⭐️⭐️⭐️⭐️⭐️
Great video. Thank you!
You're welcome, glad you liked it.

Yes, you are correct.
Nice.. and brings me back to school geomitry..
Love your shadow caster it's a bit steampunk style.
Thanks
So chris chriffin's future turned out just fine, I am happy for that.. keep up the good work Chris.

Correct 👍
Great, now you gotta do it in cross hatch!

post to social media so I can see @botzendesign detroit, facebook will be good
Any idea how to calculate a cast shado that falls on another object, what is that even callled ?shadow refraction ?
Yes, uses the same method.
