Shading Rate III
• One of the most important things to remember about the Shading Rate and
Shading Interpolation values is that they are Attributes.
• That is, they can be changed from one primitive to the next.
• So, if you have a finely patterned vase sitting in a room with flat white walls,
the vase can have a small shading rate (like 1.0) to capture its detail
• while the walls can have a very large shading rate (like 64.0) to save time
(with no visible problems).
• This is a very powerful technique that amounts to telling the renderer which
objects to spend time getting right and which objects are boring and can be
handled simply.
