摘要:
An integrated graphics pipeline system is provided for graphics processing. Such system includes a tessellation module that is positioned on a single semiconductor platform for receiving data for tessellation purposes. Tessellation refers to the process of decomposing either a complex surface such as a sphere or surface patch into simpler primitives such as triangles or quadrilaterals, or a triangle into multiple smaller triangles. Also included on the single semiconductor platform is a transform module adapted to transform the tessellated data from a first space to a second space. Coupled to the transform module is a lighting module which is positioned on the single semiconductor platform for performing lighting operations on the data received from the transform module. Also included is a rasterizer coupled to the lighting module and positioned on the single semiconductor platform for rendering the data received from the lighting module.
