| RayLight * AllocRayLight | ( | BaseDocument * | doc , |
| BaseObject * | op | ||
| ) |
Allocates a ray light for op . Destroy the allocated ray light with FreeRayLight() .
| [in] | doc | The document containing the object op . The caller owns the pointed document. |
| [in] | op | The object to allocate the ray light for. The caller owns the pointed object. |
| void FreeRayLight | ( | RayLight *& | lgt | ) |
Destructs ray lights allocated with AllocRayLight() .
| [in,out] | lgt | The ray light to destruct. If the pointer is nullptr nothing happens. The pointer is assigned nullptr afterwards. |

| const Vector64 & | p , | ||
| const Vector64 & | n | ||
| ) |
Calculates the illumination for a ray light.
| [in] | rl | The ray light to use for the calculation. The caller owns the pointed ray light. |
| [out] | color | Assigned the calculated color. |
| [out] | light_vector | Assigned the calculated light color. |
| [in] | p | The point for the illumination. |
| [in] | n | The normal for the illumination. |
