RenderTexture is a generic rendering target. To render things into it,

simply construct a render target, call begin on it, call visit on any cocos
|
|
scenes or objects to render them, and call end. For convienience, render texture
|
|
adds a sprite as it's display child with the results, so you can simply add
|
|
the render texture to your scene and treat it like any other CocosNode.
|
|
There are also functions for saving the render texture to disk in PNG or JPG format.
