Class SimpleOrthoGroupStrategy

java.lang.Object
  com.badlogic.gdx.graphics.g3d.decals.SimpleOrthoGroupStrategy

All Implemented Interfaces:

GroupStrategy

public class SimpleOrthoGroupStrategy
extends Object
implements GroupStrategy

Minimalistic grouping strategy useful for orthogonal scenes where the camera faces the negative z axis. Handles enabling and disabling of blending and uses world-z only front to back sorting for transparent decals.

States (* = any, EV = entry value - same as value before flush):

	expects	exits on
glDepthMask	true	EV | true
GL_DEPTH_TEST	enabled	EV
glDepthFunc	GL_LESS | GL_LEQUAL	EV
GL_BLEND	disabled	EV | disabled
glBlendFunc	*	*
GL_TEXTURE_2D	*	disabled
