One thing I'm trying to conceptualize in my head is whether or not cubes have highlights on individual planes. Suppose I have a light source and a cube, then if I shine collimated (light rays are parallel) light at the cube then I probably would not get a highlight on the cube unless the angle of that plane is directed towards the viewer in which that plane will be abnormally lighter than normal. Furthermore, if I take non-collimated light or the plane provides diffuse reflection I should get a highlight on the cube because some light rays will be directed at the viewer. Now in the real world we also know we never have perfectly collimated light and as well as never a perfect surface which allows for specular reflection so we will always have scattering, so in this sense would it be correct to sketch in highlights for cubes?
TL;DR
Due to the laws of physics will cubes always have highlights (other than edges)? If so is there a need to even consider these highlights?
I just want to get this out of the way before I start cubes. Thanks!
