Abstract:
In a real time graphics rendering pipeline, a method for measuring fidelity of a transformed image layer that approximates motion of 3D object geometry, comprising:factoring a scene into scene elements, where the scene elements include a 3D object or set of 3D objects in the scene;independently rendering the scene elements to separate image layers;computing a 2D transform that approximates motion of a scene element from an initial frame to a current frame in an animation sequence;computing sampling distortion of the 2D transform;using the sampling distortion to determine whether to re-render the scene element for the current frame;approximating motion of the scene element by using the sprite transform to transform an initial rendering of the scene element at the initial frame to a new position in the current frame;compositing the image layers, including at least one transformed layer, into an output image in output device coordinates to construct each frame in the animation sequence.
