class csLightPatch

A light patch

Public Methods
csDynLight* GetLight(): Get the light that this light patch belongs too
csLightPatch* GetNextLight(): Get the next light patch as seen from the standpoint of the light
csLightPatch* GetNextPoly(): Get next light patch as seen from the standpoint of the polygon
csPolygon3D* GetPolygon(): Get the polygon that this light patch belongs too
void Initialize(int n): Make room for the specified number of vertices and initialize to start a new light patch
void RemovePatch(): Remove this light patch (unlink from all lists)

Private Fields
csDynLight* light: Light that this light patch originates from.
int max_vertices: Maximum number of vertices.
int num_vertices: Current number of vertices.
csPolygon3D* polygon: Polygon that this light patch is for.
csFrustrumList shadows: List of shadow frustrums.
csVector3* vertices: Vertices.

Private Methods
csLightPatch(): Create an empty light patch (infinite frustrum)
~csLightPatch(): Unlink this light patch from the polygon and the light and then destroy

Documentation

A light patch. This is a 3D polygon which fits on a world level 3D polygon and defines where the light hits the polygon. There is a list of light patches in every polygon (all dynamic lights hitting a polygon will give rise to a seperate light patch) and there is a list of light patches in every dynamic light (representing all polygons that are hit by that particular light).
