Instance Property

normal

The variation in the surface normal vectors in a material, relative to model coordinate space.

Declaration

var normal: MDLMaterialProperty { get }

Discussion

The default normal value is zero (no variation in surface normal vectors). Typically, you assign a texture to this material property to create the appearance of detailed surface contours.
