Detailed Description

Class used to build the coarse meshes.

The build method take an array of CMeshGeom an a bitmap. This class will compute a single texture used to map every coarse mesh passed in the array.

Each mesh geom should be a coarse mesh.

The uv texture coodinates of those coarse meshes will be adjusted to fit in a single texture.

Member Function Documentation

bool NL3D::CCoarseMeshBuild::build (  const std::vector< CCoarseMeshDesc > &    coarseMeshes,
NLMISC::CBitmap &    bitmap,
CStats &    stats,
float    mulArea
) 
 

The build method.

This method will build a single texture and adjuste the UV texture coordinates of each mesh geom.

Parameters:
coarseMeshes  is a vector of coarse mesh to compute.
bitmap  will receive the final bitmap.
start  will receive various statistics about the build process.
mulArea  is the mul factor used to increase to theorical global texture size.
