Generate Normal Data for All Meshes in a 3D File
Generate Normal Data for All Meshes in a 3DS File
The GenerateNormal method exposed by the PolygonModifier class can be used to generate normal data for all meshes in a 3DS file. If VertexElementSmoothingGroup element was defined in the mesh, the generated normal data will get smoothed by the VertexElementSmoothingGroup.
This code example loads a 3DS file, visit all nodes and create normal data for all meshes.
