Abstract: A graphics processing circuit includes an anti-aliasing and stippling circuit operative to provide a primitive texture coordinate set in response to vertex data, the anti-aliasing and stippling circuit performing anti-aliasing operations, in parallel, with at least one appearance attribute determination operation on the vertex data, a rasterizer, coupled to the anti-aliasing and stippling circuit, operative to generate a pixel texture coordinate set in response to the primitive texture coordinate set, and apply an appearance value to a pixel defined by the pixel texture coordinate set, and a texture circuit, coupled to the rasterizer, operative to retrieve the appearance value from a corresponding one of a plurality of textures in a multi-texture map in response to the pixel texture coordinate set, the multi-texture map including data representing point, line and polygon texture data.

Abstract: A graphics processing circuit includes a line end generation circuit operative to generate line aligned end cap data in response to primitive data; and a rasterizer, coupled to the line end generation circuit, operative to generate pixel data representing a line to be rendered, the pixel data including the line aligned end cap data. A graphics processing method includes receiving primitive data for a line to be rendered, the primitive data including start endpoint data and stop endpoint data, determining the height and width of the line in screen space, determining line end cap orientation with respect to the line to be rendered, and determining vertices that define the line to be rendered, wherein the vertices define end caps aligned with the line to be rendered.
