ColorRGBA UniAxialCrystalShader::Shade

(

Ray &

ray

)

[inline, virtual]

The main shading function. If a ray hits a surface, this method returns a color of the hitpoint.

Parameters:

ray

The ray that hit the surface.

Returns:

The color of that specific hit.

This shader simulates a ray that hits an uniaxial crystal.

Implements Shader.
