摘要： A computer graphics processor having a renderer for rendering N views of 3D scenes is provided. Said renderer comprising a rasterizer SSR for transversing a surface grid over a surface of primitives of said 3D scenes for all N views. Furthermore, said renderer comprises a shader means PPS for determining a color of the output of the rasteriser SS and forwarding a shaded color sample along with its screen coordinates, and N screen space resamplers SSR each for resampling the shaded color sample determined by said shader means PPS according to one of the N views. This is much more efficient, because the surface traversal, texture fetching and shading computations are only performed once for the N different views. The resulting shaded colors are reused for all views. Additionally, the ability to traverse any grid over the surface of the primitive provides more rendering freedom.
摘要翻译：提供了具有用于渲染3D场景的N个视图的渲染器的计算机图形处理器。所述渲染器包括用于在所有N个视图的所述3D场景的图元的表面上横切表面网格的光栅化器SSR。此外，所述渲染器包括着色器装置PPS，用于确定光栅化器SS的输出的颜色并且随着其屏幕坐标转发阴影颜色样本，以及N个屏幕空间重新采样器SSR，每个用于重新采样由所述着色器装置确定的阴影颜色样本 PPS根据N个意见之一。这是更有效率，因为表面遍历，纹理提取和阴影计算只对N个不同的视图执行一次。所得到的阴影颜色被重用于所有视图。此外，遍历原始表面上的任何网格的能力提供了更多的渲染自由度。
