Abstract:
1. A draw processing device comprising: a draw data generator that generates draw data for use in draw processing composed of a plurality of rendering passes; and a control section that transfers the generated draw data through bus wiring and controlling the draw processing using the draw data; and a multi-pass buffer that buffers the draw data transferred by the control section through the bus wiring; a multi-pass controller that serially reads the draw data for use in individual rendering passes that comprise the draw processing out from the multi-pass buffer under control of the control section; and a draw processing section that effects the draw processing by executing the individual rendering passes using the draw data read by the multi-pass controller; wherein the draw data is geometry data containing at least coordinate values for apexes of polygons composing an image to be drawn, and texture coordinate values and brightness values for the apexes.
