Notes

This is an example showing how the same mesh may be appended to several nodes, to be rendered multiple times. It also shows how additional vertex attributes are defined in a mesh.primitive - namely, attributes for the vertex normals.

Note: The additional vertex normal attribute in this example is not yet used. This may cause a warning to be printed during the validation. The normal attribute will be used in the AdvancedMaterial section of the tutorial.
