if and 4d object casts an 3d shadow on a 3d space, what does it cast on an 2d space ?

Question

I was exploring the internet for 4d space and
object simulations when I found a very interesting site that presents and explains it nicely
But I couldn’t find anywhere mention of what a 4d object projects onto 2d space

Here is the site for anyone interested:

Answer 1

It would also be 2d? How would it cast a 3d shadow onto a 2 dimensional space?
