Abstract
Efficiently handling restart indices during tile-based deferred rendering (TBDR) by graphics processing units (GPUs) is disclosed herein. In some aspects, a processor circuit of a GPU determines, during a tile sorting pass, a location of a restart index in a plurality of indices of an index buffer associated with a primitive topology, and determines a skip count indicating a number of indices to skip during a tile rendering pass, based on the primitive topology and the location of the restart index. In some aspects, the processor circuit also determines visibility statuses corresponding to primitives of the primitive topology, and generates visibility data comprising the visibility statuses and the skip count. Subsequently, during the tile rendering pass, the processor circuit bypasses fetching of the restart index, based on the skip count. According to some aspects, the processor circuit may also assemble the primitives based on the visibility data.
