TECHNIQUES FOR DEFERRED DECOUPLED SHADING

摘要

Various embodiments are generally directed to techniques for reducing the processing demands of shading primitives in rendering a 2D screen image from a 3D model. A device includes a fine rasterizing component to employ multiple screen image samples per screen image pixel to perform fine rasterization to identify a set of visible primitives, a coarse rasterizing component to employ a single shading image sample per shading image pixel to perform coarse rasterization from the same perspective as the fine rasterization to identify at least one primitive along a path of a shading image pixel, and a shading component to shade a primitive identified by a screen image sample of a first screen image pixel as visible within the shading image pixel and identified as along the path of the shading image sample associated with the shading image pixel to derive a color value. Other embodiments are described and claimed.

1. A device to render two-dimensional (2D) imagery from three-dimensional (3D) model data comprising:
a fine rasterizing component to employ multiple screen image samples per screen image pixel of a screen image to perform fine rasterization of a 3D model to identify a set of visible primitives of the 3D model that are visible from a perspective of the screen image; a coarse rasterizing component to employ a single shading image sample per shading image pixel of a shading image that corresponds to the screen image to perform coarse rasterization of the 3D model from the perspective of the screen image to identify at least one primitive along a path of a shading image pixel; and a shading component to shade a primitive identified by a screen image sample of a first screen image pixel as visible within the shading image pixel and identified as along the path of the shading image sample associated with the shading image pixel to derive a first color value.
