Shading Normal VEX node

Computes the normal at the location specified by the P position.

See also: Shading Area, Shading Derivative

This operator computes the normal at the location specified by the P position. The resulting normal is computed as the cross product of the derivatives of P, and is adjusted so that interpolated normals are relatively correct.

If P, N, or Ng are not connected, the global variables by the same names will be used instead.
