Package gaiasky.util.gdx.g3d.decals

Class CameraGroupStrategy

  • All Implemented Interfaces:
    com.badlogic.gdx.graphics.g3d.decals.GroupStrategy, com.badlogic.gdx.utils.Disposable
    public class CameraGroupStrategy
extends java.lang.Object
implements com.badlogic.gdx.graphics.g3d.decals.GroupStrategy, com.badlogic.gdx.utils.Disposable

    Minimalistic grouping strategy that splits decals into opaque and transparent ones enabling and disabling blending as needed. Opaque decals are rendered first (decal color is ignored in opacity check).
    Use this strategy only if the vast majority of your decals are opaque and the few transparent ones are unlikely to overlap.

    Can produce invisible artifacts when transparent decals overlap each other.

    Needs to be explicitly disposed as it might allocate a ShaderProgram when GLSL 2.0 is used.

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

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