Efficient rendering of multiple frame buffers with independent ray-tracing parameters
Abstract:
One embodiment of the present invention sets forth a technique for rendering a plurality of images from a graphics scene in one rendering pass. Each image from the plurality of images may include or preclude certain scene objects and shading effects associated with the scene objects, as specified by a set of rules associated with a corresponding frame buffer that is configured to store the image. During the rendering pass, a ray-tracing application performs at least one complete ray casting operation, which is concluded according to the set of rules. At each stage in the ray casting operation, individual rules for each frame buffer determine whether results from that stage should be saved in the frame buffer. The plurality of images may represent different segments of a final rendered image, and may be combined arbitrarily in a compositing phase to generate the final rendered image.
