PENCIL INK RENDER USING HIGH PRIORITY QUEUES

摘要

Examples described herein generally relate to rendering digital pencil ink on a display of a computer device. The computer device may render a frame via a graphics queue of a graphics processing unit (GPU). The computer device may fetch updated digital pencil ink input from an input buffer at a designated time before scanning at least a portion of the frame including the digital pencil ink. The computer device may determine a set of input stamps based on the updated digital pencil ink input, each input stamp being associated with stamp properties. A compute shader thread for each block within a portion of the frame may determine whether each of the input stamps intersects the block. At least one compute shader thread for each pixel of a respective block may determine a cumulative effect of each of the input stamps intersecting the respective block on the pixel based on the stamp properties.
