Select3D_SensitiveTriangle Class Reference

A framework to define selection of triangles in a view. This comes into play in the detection of meshing and triangulation in surfaces. In some cases this class can raise Standard_ConstructionError and Standard_OutOfRange exceptions. For more details see Select3D_SensitivePoly. More...
