Class Terrain

java.lang.Object

com.codename1.gpu.shaders.Terrain

public final class Terrain
extends Object

Ground. Layers are chosen per pixel from height and slope, so any mesh (a heightfield, a Primitives.grid displaced by VERTEX_OFFSET, a level built from boxes) is painted without UVs or splat textures. Use with Material.Type.PBR or Material.Type.LAMBERT.

Field Summary

Fields

Modifier and Type	Field	Description
static final String	GRASS	VEC3 colour of flat ground.
static final String	LEVELS	VEC4: sand top height, snow line height, the slope (normal y) below which rock shows, and the blend width.
static final String	ROCK	VEC3 colour of steep ground.
static final String	SAND	VEC3 colour below LEVELS.x: beach, mud.
static final String	SCALE	FLOAT repeats of the detail noise per world unit.
static final String	SNOW	VEC3 colour above LEVELS.y.
static final String	WATERLINE	FLOAT world height of the waterline, under which ground darkens as if wet.

Method Summary

Modifier and Type	Method	Description
static ShaderMaterial	layered()	Sand, grass, rock and snow by height and slope, with noise breaking up every boundary and wet ground along the waterline.
static ShaderMaterial	rock()	Bare stone on every face, its strata and grain mapped by Shading.boxUv so cliffs and boulders need no UVs.
