Detailed Description

A class used to render instances sorted by MeshGeom first, then per material, where possible.

This allow optimisation because less renderState swapping are needed. WARNING: if you add MeshGeom to 2 different CMeshBlockManager at same times, it won't work, and will certainly crashes (not checked/assert).

NB VBHeap part works, even if no User interface use it. It don't give greate performance Add, but will may be used.

Member Function Documentation

void NL3D::CMeshBlockManager::addInstance (  IMeshGeom *    meshGeom,
CMeshBaseInstance *    inst,
float    polygonCount
) 
 

Add an instance of a MeshGeom to render.

Only CMeshBaseInstance can be added. For now, only CMeshGeom and CMeshMRMGeom are known to work.

bool NL3D::CMeshBlockManager::addVBHeap (  IDriver *    drv,
uint    vertexFormat,
uint    maxVertices
) 
 

Add a Heap for a given vertexFormat.

Any meshGeom added with addInstance() which has this vertex Format may fit in this heap. return false and fail if the heap can't be allocated or if the heap with same vertexFormat still exist.
