Illuminate the light. The ray will be changed into a ray pointing to the light source, hence we call it shadow ray.
| ray | Here a new ray (shadow ray) will be stored | |
| intensity | The intensity of the ray (i.e. color) will be given back here | |
| index | Specify index value of the light ray. The value should be in the range [0; GetNumberOfRays). |
Implemented in PointLight, and QuadAreaLight.
| unsigned int Light::GetNumberOfRays | ( | ) | const [inline, virtual] |
Return number of rays required to accomplish the shading produced by this light. (i.e. Point light = 1 ray) area light = n rays)
Reimplemented in QuadAreaLight.
