Abstract: In graphics applications, objects including rotating objects having geometric detail or surface relief are rendered in render targets where pixels are assigned color and depth values by color and depth buffers. A pixel shader performs ray intersection calculations on a primitive approximating the object in the render target to generate three-dimensional world space positions for the pixels. Samples for each pixel are taken around a primitive's axis of rotation, and for each sample, the object in the render target is queried to gather color and depth data for the pixel. The query results are composited and a blurred object is provided in a scene at a desired location and at a depth according to depth data retrieved from the depth buffer.
