Vragments - Relocatability as an Extension to Programmable Rasterization Hardware

We propose an extension to the pixel pipeline of current programmable rasterization hardware to include the possibility to freely locate the rasterization position of fragments and pixels. The corresponding new primitive name is Vragment (variable fragment). We show how this new functionality could lead to new and wider classes of algorithms in computer graphics, especially in image processing, scientific visualization, geometric modeling, and rendering. A GPU-assisted simulator for programs running on the proposed architecture is presented.
