MeshGeometry.Normals Property
Gets the collection of Point elements that represent the surface normals of the MeshGeometry.
Thread safety: This property is thread-safe but the returned object is not.
Syntax
public PointCollection Normals { get; }Property Value
Remarks
If this collection is not empty, it should contain mesh surface normals; one for each vertex in the Vertices array. These normals will be used for calculating the light of the surface, if lighting is enabled in the Material instance used to render the mesh. If lighting is not enabled, the normals will not be used.
If the collection is empty and lighting is enabled, surface normals will be calculated automatically when the mesh is rendered. But if the normals are known beforehand, it is more efficient and may give better rendering if the normals are specified explicitly.
