Patent number: 9483861Abstract: This disclosure describes techniques for using bounding regions to perform tile-based rendering with a graphics processing unit (GPU) that supports an on-chip, tessellation-enabled graphics rendering pipeline. Instead of generating binning data based on rasterized versions of the actual primitives to be rendered, the techniques of this disclosure may generate binning data based on a bounding region that encompasses one or more of the primitives to be rendered. Moreover, the binning data may be generated based on data that is generated by at least one tessellation processing stage of an on-chip, tessellation-enabled graphics rendering pipeline that is implemented by the GPU. The techniques of this disclosure may, in some examples, be used to improve the performance of an on-chip, tessellation-enabled GPU when performing tile-based rendering without sacrificing the quality of the resulting rendered image.Type: GrantFiled: March 15, 2013Date of Patent: November 1, 2016Assignee: QUALCOMM IncorporatedInventors: Christopher Paul Frascati, Avinash Seetharamaiah, Andrew Evan Gruber
