Abstract
There is provided a method and apparatus for supporting an image rendering using ray tracing. For at least some elements (e.g. pixels), ray tracing results for previously evaluated elements are used to predict ray tracing results for the current element. These previously evaluated elements can be elements which are proximate to the current element. Feasibility testing and prediction can be performed to determine whether a prediction can be made, and the ray hit test and the opaqueness testing can determine whether the prediction is valid. If testing fails, a full ray tracing operation can be performed for the current element. The operations can be implemented using multithreading. Ray tracing patterning and resolution of elements used for prediction purposes can be adjusted based on prior performance.
