Interface OffscreenCullable

All Superinterfaces:

Cullable

All Known Implementing Classes:

public interface OffscreenCullable
extends Cullable

A cullable that represents and offscreen rendered piece of scene graph that will be used later by a parent object.

An offscreen cullable has two parts - the scene graph that it contains, and the buffer that it should be rendered to. The buffer could be a pbuffer or frame buffer object (FBO). The implementation is not specified at this level.

Method Summary

LayerCullable	getCullableLayer(int layerIndex) Get the cullable layer child that for the given layer index.
OffscreenBufferRenderable	getOffscreenRenderable() Fetch the renderable that this offscreen cullable will draw to.
boolean	isRepaintRequired() Get the current state of the repainting enabled flag.
int	numCullableChildren() Returns the number of valid cullable children to process.

Method Detail

isRepaintRequired

boolean isRepaintRequired()

Get the current state of the repainting enabled flag.

Returns:

true when the texture requires re-drawing

getCullableLayer

LayerCullable getCullableLayer(int layerIndex)

Get the cullable layer child that for the given layer index.

Returns:

The layer cullable at the given index or null

numCullableChildren

int numCullableChildren()

Returns the number of valid cullable children to process. If there are no valid cullable children, return 0.

Returns:

A number greater than or equal to zero or -1

getOffscreenRenderable

OffscreenBufferRenderable getOffscreenRenderable()

Fetch the renderable that this offscreen cullable will draw to.

Returns:

The renderable instance that we deposit pixels to
