I am having a conversation with a co-worker about the properties of light on cylinders. Can someone please help clear this up? I have posted an image that I whipped up in Xara X to illustrate the two views. I know that the tops of the cylinders are not shaded correctly...I'm more interested in the sides.
The question is. If light is hitting a cylinder at a 45 degree angle, will the cylinder be evenly shaded top to bottom like the cylinder on the left or will it have a diagonal shade like the cylinder on the right??
Thanks,
Robert
