Function Documentation

void combineCallback (  double    coords[3], double *    vertex_data[4], float    weight[4], double **    dataOut )

Callback used to interpolate the average RGB values for newly created vertices. combineCallback( ) returns new vertex coordinates and color data if the GLU_TESS_COMBINE is invoked. The new vertex is created by referencing the contents of vertex_data. coords is the location of the new vertex. weight[4] is used to interpolate the average RGB value for newly created vertices.

void vertexCallback (  void *    vertex )

References the coordinate and color data. vertexCallback( ). This function creates a pointer to the vertex's data (the vertex_data pointer) that is passed to it and references the coordinate and color data.
