16.90.5.49 - texturemap (SceneScript element)

 <texturemap "T" P1 P2 P3

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

The  <texturemap language element allows you to apply procedural textures to objects. This has priority over imagemaps, so if you texturemap, any imagemap will not appear. Bump mapping works with texturemaps. "T" is the name of the specific texture. P1, P2 and P3 are the parameters (if any) to the texure being used; if a texture uses less than the available parameters (indicated in the following table by n/a), you do not need to specify the remaining ones.

The  <texturemap language element uses the three color statements ( <color0,  <color1 and  <color2) to source colors to be used in the various textures. Not all textures use all the colors; colors used are indicated.

In the following table, the suggested numbers are for a sphere of radius 4. As object sizes in the rendering space change, the textures may change as well, requiring readjustment of parameters. However, texture behavior is independent of rendering resolution.

 Note:

If you desire to use a texture as a 3d global texture over more than one object, you must use the  <axis language element. The  <axis and  </axis language elements provide the 3d texture engine with a point of reference.

See also the  <seed language element.
