Diffuse has been called the backbone of reality
. I admit this isn't my statement
, I have taken it off Visual Magic Magazine in this article:
Diffuse is essentially the amount of light
that hits the surface of an object and is diffused, then reflected at the viewer. In terms of computer graphics
, it is the property
that will dictate to the renderer
exactly which amount of rays to reflect
. Thus image maps
can be crafted to represent the differing diffusion of a given surface
On average, and object that you would commonly see will only diffuse somewhere between 60% to 80% of the light
that hits it.
Diffuse is the property
how bright an object is which essentially dictates the brightness
and therefore the overall colour
of an object. As a result it really defines what we perceive as reality.
