Understanding Diffuse, Specular, and Defuse Surfaces in Computer Graphics

In computer graphics, a diffuse surface is one that scatters light in all directions equally, without any preference for a particular direction. This means that the surface appears to be roughly uniform and does not have any noticeable texture or pattern.

In contrast, a specular surface is one that reflects light in a specific direction, often with a high degree of gloss or shine. This can create a sense of depth and detail on the surface, as the light reflects off of various angles and features.

A defuse surface, on the other hand, is one that scatters light in all directions equally, but with a much lower intensity than a diffuse surface. This can create a more subtle, muted appearance, as the light is scattered in all directions without any strong reflections or highlights.

In summary, diffuse surfaces are uniform and do not have any noticeable texture or pattern, specular surfaces reflect light in a specific direction with high gloss, and defuse surfaces scatter light in all directions with low intensity.
