buildMesh()

template<typename VertexType = Vertex>

void oe::scene::loader::Bezier< VertexType >::buildMesh ( const BuildMeshInfo &  params, BezierMeshType &  result  )

inline

Build a mesh Bezier surface (using De Casteljau's algorithm)

Parameters

params	Parameters, see BuildMeshInfo
result	Final mesh that will contains bezier surfaces

For example, lower lod values could be used to generate mesh for collision or simplified render

Returns

the mesh created
