Although, this is comparable to that in these areas (in figure 2 Strict 1D averaging on the midline ML in which only black texels are selected to contribute) yields more accurate averaging, but requires 2D calculations (i.e., area overlap calculations) in 1D scanline calculations, resulting in a Computationally Intensive Techniques

Embodiment Construction

[0029] Detailed Description of Preferred Embodiments

[0030] image 3A forward map pipeline as described in the first embodiment of the present invention is shown. The forward mapping pipeline includes texture space rasterizer TS, texture memory TM, texture space resampler TSR, pixel shader PS, first pass and second pass blur unit 1PB, 2PB, first pass and second pass screen Spatial resamplers SSR1, SSR2 and pixel fragment (fragment) synthesizer PFC.

[0031] First, the basic operation of the forward rendering pipeline is described. Rasterization is performed in texture space, and the texture space rasterizer TS traverses primitives projected on texture maps by selecting texture coordinates as variables in the rasterization process. The texture space rasterizer TS can traverse the texture map on the texture grid. Splats texels bounded by rasterized primitives or polygons onto screen-space pixels.

[0032] Thus, the pixel shader PS and the texture space resampler TSR (wher...

Abstract

A computer graphics processor with a forward mapped renderer is provided. The renderer includes a texture space rasterizer (TS) that rasterizes primitives in texture space, a color generation unit that determines the color of the output of the texture space rasterizer (TS) and provides color samples along with coordinates PS), a two-pass screen space resampler (SSR1, SSR2) for resampling the color samples determined by the color generation unit (PS), and at least one pass correlation with said screen space resampler (SSR1, SSR2) There is at least one connected one-dimensional fuzzy filtering unit (1PB, 2PB), which performs one-dimensional fuzzy filtering before performing the at least one pass.

Description

technical field [0001] The invention relates to a computer graphics processor and a method of rendering images. Background of the invention [0002] In the field of computer graphics and video processing, there is an ongoing effort to improve system rendering capabilities to obtain more realistic images with less computation. [0003] Traditionally, texture mapping to 3D surface projections is achieved by back-mapping from pixel regions to surface textures. In Computer Graphics (SIGGRAPH'80 Proceedings) 1980, Vol. 14(3), pp. 279-285, "3-d transformations of images in scanline order" by Edwin Catmull and Alvy Ray Smith Three-dimensional transformation of images)", an alternative method is shown. Transforms a textured surface as a 2D image until it conforms to the projection of an arbitrarily placed polygon in 3D space. This 2D transform or map can be decomposed into a series of two orthogonal 1D transforms, called horizontal and vertical scan line sequences. In other word...
