Detailed Description
The static and all dynamic lightmaps for one polygon.
Member Function Documentation
|
|
Allocate the lightmap. 'w' and 'h' are the size of the bounding box in lightmap space. r,g,b is the ambient light color used to initialize the lightmap. |
|
|
Cache the lightmaps in the precalculation area. 'id' is a global id that is used to identify objects. |
|
|
Convert the lightmaps to the correct mixing mode. This function does nothing unless the mixing mode is nocolor.
This function also calculates the mean color of the lightmap. |
|
|
Delete a ShadowMap. NOTE!!! This function only works if the ShadowMap was the LAST CREATED for this LightMap!!! It is ment for dynamic lights that do not reach the polygon but this can only be seen after trying. |
|
|
Read from the cache. Return true if succesful. 'id' is a global id that is used to identify objects. |
|
|
Set the size of one lightmap cell (default = 16). Do not directly assign to the lightcell_size variable, as lightmap_shift also has to be updated. |
