Method And Apparatus For Efficient Generation Of Texture Coordinate Displacements For Implementing Emboss-Style Bump Mapping In A Graphics Rendering System

US Patent:
6980218, Dec 27, 2005
Filed:
Nov 28, 2000
Appl. No.:
09/726218
Inventors:
Eric Demers - Redwood City CA, US
Mark M. Leather - Saratoga CA, US
Mark G. Segal - Santa Cruz CA, US
Assignee:
Nintendo Co., Ltd. - Kyoto
International Classification:
G09G005/00
US Classification:
345584, 345582
Abstract:
A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. The system includes a graphics and audio processor including a 3D graphics pipeline and an audio digital signal processor. Emboss style effects are created using fully pipelined hardware including two distinct dot-product computation units that perform a scaled model view matrix multiply without requiring the Normal input vector and which also compute dot-products between the Binormal and Tangent vectors and a light direction vector in parallel. The resulting texture coordinate displacements are provided to texture mapping hardware that performs a texture mapping operation providing texture combining in one pass. The disclosed pipelined arrangement efficiently provides interesting embossed style image effects such as raised and lowered patterns on surfaces.
