sgLightMap Class Reference #include <sgLightMap.h> Inheritance diagram for sgLightMap: [legend] Detailed Description The base class for generating mission level or real-time light maps for any sceneObject. All actual work is performed in the descendent class' sgLightMap::sgCalculateLighting method. Public Member Functions   sgLightMap (U32 width, U32 height)   ~sgLightMap () virtual void  sgCalculateLighting (LightInfo *light)=0   Object specific light mapping calculations are done here. Data Fields Point3D  sgWorldPosition   The world space position that the texture space coord (0, 0) represents. Point3D  sgLightMapSVector   Defines the world space directional change corresponding to a change of (+1, 0) in the light map texture space. Point3D  sgLightMapTVector   Defines the world space directional change corresponding to a change of (0, +1) in the light map texture space. Protected Types typedef BVPT< sgStaticMeshInfo >  sgStaticMeshBVPT Protected Member Functions void  sgGetIntersectingObjects (const Box3F &surfacebox, const SceneObject *skipobject) Protected Attributes U32  sgWidth U32  sgHeight sgColorMap *  sgTexels   The light map color buffer.

Implemented in sgPlanarLightMap, and sgTerrainLightMap. void sgLightMap::sgGetIntersectingObjects ( const Box3F &  surfacebox, const SceneObject *  skipobject   ) [protected] Field Documentation U32 sgLightMap::sgWidth [protected] U32 sgLightMap::sgHeight [protected] sgColorMap* sgLightMap::sgTexels [protected] The light map color buffer. Point3D sgLightMap::sgWorldPosition The world space position that the texture space coord (0, 0) represents. Point3D sgLightMap::sgLightMapSVector Defines the world space directional change corresponding to a change of (+1, 0) in the light map texture space. Similar to the tangent vector in dot3 bump mapping. Point3D sgLightMap::sgLightMapTVector Defines the world space directional change corresponding to a change of (0, +1) in the light map texture space. Similar to the binormal vector in dot3 bump mapping. Vector<SceneObject *> sgLightMap::sgIntersectingSceneObjects [protected] sgStaticMeshBVPT sgLightMap::sgIntersectingStaticMeshObjects [protected]
