192: Show3DNormals(Handle, Enable);


This intrinsic causes the normals to be displayed as short line segments at each vertex of a mesh. This is useful for debugging purposes.




Handle. This argument is an integer handle created by the Add3DObject intrinsic that specifies the mesh that should display normals. The handle must be for a mesh.


Enable. This argument is an integer Boolean that enables or disables the display of normals.
