Class TLspHypsometricCreaseShader

java.lang.Object

com.luciad.tea.lightspeed.hypsometry.ALspHypsometricShader

com.luciad.tea.lightspeed.hypsometry.TLspHypsometricCreaseShader

public class TLspHypsometricCreaseShader
extends ALspHypsometricShader

A shader that computes ridges and valleys. The computed hypsometric value is a measure for how strongly the terrain deviates from a locally fitted plane. When computing ridges and valleys, it can range from -pi/2 for sharp valleys to pi/2 for sharp ridges. When only computing either ridges or valleys, it can range from 0 for no ridges resp. valleys, to pi/2 for sharp ridges resp. valleys.

This shader provides similar results to the TLcdHypsometricCrease value provider.

Since:

2012.0
