摘要
A device for rendering to multiple viewpoints of a stereoscopic display is provided. The device includes vertex shaders which receive vertices corresponding to primitives and process viewpoint dependent information. The device also includes a primitive replication unit which replicates primitives according to a number of viewpoints supported by the stereoscopic display. The primitive replication unit adds unique view tags to each of the primitives which identify the viewpoint that the respective primitive is destined for. Each replicated primitive is processed by a rasterizer and converted into pixels. The rasterizer adds a view tag to the rasterized pixels so that the pixels identify a respective primitive and identify a respective pixel buffer that the pixel is destined for. The pixels can then be processed by a pixel processing unit and written to a pixel buffer corresponding to a respective viewpoint. The pixels are subsequently output to the stereoscopic display.
