Title:
描画モードに基づいて隠面処理の順番を動的に再構成する方法および装置
Document Type and Number:
Japanese Patent JP4680412
Kind Code:
B2
Abstract:
A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. The system includes a graphics and audio processor including a 3D graphics pipeline and an audio digital signal processor. A reconfigurable graphics pipeline has a hidden surface removal stage that may be placed at different locations within the pipeline depending on pipeline rendering mode. When the pipeline operates in certain rendering modes, the hidden surface removal operation can be performed early in the pipeline-allowing the pipeline to avoid wasting its time imaging obstructed surfaces. For other (e.g., alpha based) rendering modes, the hidden surface removal operation is performed near the end of the pipeline-when the pipeline has developed sufficient additional information required by the particular rendering mode to resolve depth comparisons.
