I find myself confused as to the exact distinction between diffuse and
specular reflectivity. All objects are mirror-like and specular;
diffuse materials are just this reflection spread out according to the
unevenness of the surface texture. If you tune radiosity settings to a
count of one and a very low error bound you can see that this is what
radiosity is doing. The bright-spot shine of a specular highlight is
simply the result of a light source being so much brighter than
everything it's illuminating. Yes?
