Abstract
A method, system, and computer-readable storage medium are disclosed for rendering artwork using a graphics processing unit (GPU). The GPU may comprise a depth buffer and a stencil buffer. Artwork input comprising one or more dirty regions and one or more clip paths may be received at the GPU. A culling operation may be performed on the artwork input. The culling operation may comprise configuring the depth buffer to reject pixels located outside a union of the one or more dirty regions. A clipping operation may be performed on the artwork input. The clipping operation may comprise configuring the stencil buffer to reject pixels located outside an intersection of the one or more clip paths.
