C++ (Cpp) lineIndicesFromQuadVertexArray Examples

Example #1

//--------------------------------------------------------------------------------------------------
/// Generates simplified mesh as line drawing
/// Must call generateSurface first 
//--------------------------------------------------------------------------------------------------
