Source Ray
The Source Ray is a point which emits rays along specified direction cosines. This is useful for debugging, for example, the direction cosines may be used to recreate a ray that causes geometry errors.
The parameters are:
| Parameter # | Definition |
| 1-5 | See " Parameters common to all source objects " . |
| 6-8 | Cosines: The local X, Y, and Z direction cosines of the ray. These are automatically normalized. |
| 9 | Random Seed: If not zero, the random number generator is reseeded with the specified value. This allows identical rays to be generated which subsequently have random but reproducible properties, such as when bulk or surface scattering is on. |
