In-Depth Information
When surfaces have more than microscopic roughness, this reads as physical depth. A good example of
this is concrete or tree bark. In cases such as these, the actual surface is made up of many small variations
in surface color and quality. With the differences in texture packed closely together, the end result is one
complex texture. Differences in highlight, reflectivity, color, and roughness give character to these materials
that often have an organic or aged appearance.
