Class VolumeRenderer

java.lang.Object

gaiasky.render.system.AbstractRenderSystem

gaiasky.scene.system.render.VolumeRenderer

All Implemented Interfaces:

com.badlogic.gdx.utils.Disposable, IObserver, IRenderSystem, Comparable<IRenderSystem>

public class VolumeRenderer
extends AbstractRenderSystem
implements IObserver

Renders models with arbitrary shaders, kept in a map. The shaders themselves are defined in the Volume component. Optionally, the shader may receive one or more 3D texture (density, color, etc.). In this case, the shader must be a full-on volume rendering shader.
