SYSTEM AND METHOD FOR HIGH-SPEED EXECUTION OF GRAPHICS APPLICATION PROGRAM INCLUDING SHADING LANGUAGE INSTRUCTION

摘要

PROBLEM TO BE SOLVED: To perform high-speed execution of graphics application programs, including shading language instructions, that utilize 3D graphics hardware.;SOLUTION: A method involves expressing a graphics computation in a platform-independent procedural shading expression, converting the expression into an intermediate representation such as a tree, and then translating it into a sequence of parametric shading expressions. The method can alternatively process the intermediate tree representation using a cost-based, tree-grammar recognition program such as iburg. The result is a platform-specific and least-cost, in terms of the underlying hardware, sequence of parametric shading expressions that realizes the graphics computation. Platform-independent RenderMan(R) Shading Language programs are translated into fast-executing, platform-specific OpenGL(R) or Direct3D(R) executable code.;COPYRIGHT: (C)2011,JPO&INPIT
