public class TLspHypsometricSlopeAngleShader
extends ALspHypsometric3DDirectionShader

A shader that computes the the angle between a given 3D reference direction and the normal. The reference direction should generally have a positive z-component. The angle is expressed in radians. Negative values are clamped to 0, so the values lie in the range [0, pi/2).

This shader is typically useful for computing the slope of the terrain, by using the reference direction (0, 0, 1). The computed values then correspond to the inclination of the terrain, ranging from 0 for horizontal terrain, over larger values for increasingly sloping terrain, to a value of pi/2 (in the limit) for vertical cliffs.

This shader provides similar results to the TLcdHypsometricSlopeAngle.
