Detailed Description

This class defines a more configurable marble texture. Technically, this is still a cloud texture.

This material supports the following properties:

material1a (Required) First component of first marble material material1b (Required) Second component of first marble material material2a (Required) First component of second marble material material2b (Required) Second component of second marble material break_point (Required) Noise value where material breaks from first marble material into second noise_scale (Required) How much to scale noise by. Larger values give grainier marbles.

Here is the call graph for this function:

double MarbleMaterial::get_refraction_index ( const Point3D & intersesction_point ) const [virtual]

Get the refraction index at the point. This may produce some bizarre images if the refraction indexes vary among the materials. It will certainly be incorrect for a noise material as varying refraction within the object will not be honored. Only the location on the surface will be considered.
