void set_base(face *f,light_map_pic *lmp,vector& pos=vector(0,0,0))
| Parameter | Type | Description |
|---|---|---|
| f | face * | face using the light_map |
| lmp | light_map_pic * | light_map_pic for this light_map |
| pos | vector& | position for the light_map in world co-ordinates |
None
This function precompute internal data required when mapping points from the light_map space into world space and vice-versa.
