Gpu Accelerated Path Rendering Presentation Gtc 2012

Gpu Accelerated Path Rendering Fastforward Ppt Session level: beginner ash depend on a resolution independent 2d rendering paradigm that gpus have not traditionally accelerated. this tutorial explains a new op ortunity to greatly accelerate vector graphics, path rendering, and immersive web standards using the gpu. by attending, you. This document provides an overview of gpu accelerated path rendering using the nv path rendering api. it introduces path rendering as a resolution independent 2d graphics technique where rendering order determines occlusion and transparency. Advances in graphics hardware have largely ignored accelerating resolution independent 2d graphics rendered from paths. we introduce a two step “stencil, then cover” (stc) programming interface. Final demo shows rendering the entire front page from the new york times fullscreen at 80 fps without clipping or culling. zooming in didn't appear to affect the framerate, but adding a non affine transform brought it down to about 70 fps. This tutorial explains a new opportunity to greatly accelerate vector graphics, pathrendering, and immersive web standards using the gpu< strong>. by attending, you will learn how to write openglapplications that accelerate the full range of path rendering functionality. It shows how gpu accelerated path rendering with nv path rendering compares to other path rendering systems in both performance and quality. you can compare nv path rendering to cairo, skia, qt, direct2d (requires vista and windows 7), and the openvg reference implementation.
