International Classification:

G06T 1/60
G06F 3/06

Abstract:

The described techniques provide for bin-based rendering where the scene geometry in a frame is subdivided into bins or tiles, and bins are resolved concurrently with the rendering of a next bin. For example, a graphics processing unit (GPU) may process an entire image and sort transactions (e.g., rasterized primitives, such as triangles) into bins. For the rendering of each transaction, a device may identify a memory address of a memory block (e.g., a unit or portion of internal GPU memory (GMEM)) the transaction will be written (i.e., rendered) to. The device may thus prepare the memory block for rendering (e.g., by performing a resolve operation, a clear operation, or an unresolve operation on the memory block), such that the memory block is prepared prior to rendering of the particular transaction. As such, transactions of a bin may be resolved concurrently with rendering of transactions of a next bin.

Abstract:

A graphics processing unit (GPU) may include a triangle setup engine (TSE) configured to determine coordinates of a triangle, rotate coordinates of the triangle based on an angle. To rotate the coordinates, the TSE generates coordinates of the triangle in a rotated domain, and determines coordinates of a bounding box in the rotated domain based on the coordinates of the triangle in the rotated domain. The TSE determines a first plurality of parallel scanlines in the rotated domain, and a second plurality of parallel scanlines in the rotated domain. The first and second pluralities of scanlines are perpendicular. The TSE determines whether the bounding box coordinates are located within two adjacent scanlines. If the bounding box coordinates are located within the two adjacent scanlines, the TSE removes the triangle from the scene.
