+Normal is usually the most recently calculated surface normal at the current point on the surface being rendered or sampled, but may be modified by other shaders, e.g. [[Redirect Shader]] whose purpose is to change the normal to cause displacement shaders to displace in different directions.
 When used in the context of displacement, for example in a function network that feeds a displacement shader, Normal depends on where the node is connected with respect to [[Compute Terrain]] and [[Compute Normal]], and may also depend on other displacement shaders. Initially the normal is derived from the undisplaced surface being rendered. On imported objects such as OBJs or TGOs, normals are often provided by the object file and (optionally) interpolated to give a smooth surface for displacement and shading. On terrains these are initially set to the normal at the point on the flat planet from which the terrain was displaced, but may be updated by [[Compute Terrain]] or [[Compute Normal]] nodes to provide a more detailed representation of the surface relief.
