§ 16.90.5.21 - dmap (SceneScript element)

 <dmap "T" P1 P2 P3> 

This language element may be used inside a  <trait>  block.

"T" is a quoted name for a decision mapping method. P1, P2 and P2 may be expressions.

Decision mapping allows you to use a decision metric (such as a checkerboard) to decide whether to apply the  <texturemap>  or  <texturemap2>  language element on a particular point for any object.

For instance, you can set up  <texturemap>  to generate marble; then set up  <texturemap2>  to generate wood. Then, using the checkerboard decision map, you can create a checkerboard that alternates between marble and wood.

The following decision maps are supported:

Name	P1	P2	P3	Details
checker	Size	n/a	n/a	Switches back and forth in a classic checker pattern
noise	variance	threshold	gain	Applies noise as a switch
