Member Function Documentation

◆ pickVertexIBO_opt()

GLuint ACG::DrawMeshBase::pickVertexIBO_opt ( )
inline

get an index buffer mapping from openmesh vertices to drawmesh vbo vertices

Returns
index buffer object (UNSIGNED_INT), might be 0 if the openmesh object is a point cloud

Definition at line 121 of file DrawMesh.hh.

Member Data Documentation

◆ vertices_

std::vector<char> ACG::DrawMeshBase::vertices_
protected

final vertex buffer used for rendering raw byte array, use write__() functions for access
