Abstract:
Systems, apparatuses, and methods for implementing a single pass stipple pattern generation process are disclosed. A processor initiates parallel execution of a first and second plurality of wavefronts. A first wavefront of the first plurality of wavefronts converts a first local coordinate into a first global coordinate, wherein the first local coordinate corresponds to a first portion of a primitive. Also, a first wavefront of the second plurality of wavefronts applies a first attribute to the first global coordinate prior to a second wavefront, of the first plurality of wavefronts, converting a second local coordinate of a second portion of the primitive into a second global coordinate. The second plurality of wavefronts generate image data based on applying the first attribute to global coordinates generated by the first plurality of wavefronts, and the image data is conveyed for display on a display device.
