Cocos3D - Take various screenshots in the background

Using Cocos3D, is it possible to take screenshot of the 3D model in the background without the user knowing it?For pre-processing purpose and other usage, I want to take screenshots of the 3D model at various angles. Following the Render-To-Texture capability, I noticed when my scene is not visible, the drawSceneContentWithVisitor: method only execute once rather than at every rendering cycle. For obvious reason, the CC3GLFramebuffer* won't get updated with new data, hence, I'm only able to take the initial screenshot.Thanks....Read more

But, it is crashing when i move my part code into separate thread. Here is my sample code: -(void) loadFirstScene{CC3PODResourceNode* podRezNode = [CC3PODResourceNode nodeWithName: @"FirstModel"];podRezNode.resource = [IntroducingPODResource resourc...Read more
