Graphics primitives generated by a decomposition of the graphics object to be displayed, are rasterized by interpolating a two-dimensional subset of the threedimensional texture. For each, primitive a texture image is constructed in response to the interpolation having a size covering the, primitive.

Why it's free to use
- Filed May 1, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 1, 2020.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
