Dynamic Canvas for Non-Photorealistic Walkthroughs
Abstract
The static background paper or canvas texture usually used for non-photorealistic animation greatly impedes the sensation of motion and results in a disturbing shower door effect. We present a method to animate the background canvas for non-photorealistic rendering animations and walkthroughs, which greatly improves the sensation of motion and 3D immersion. The complex motion eld induced by the 3D displacement is matched using purely 2D transformations. The motion eld of forward translations is approximated using a 2D zoom in the texture, and camera rotation is approximated using 2D translation and rotation. A rolling-ball metaphor is introduced to match the instantaneous 3D motion with a 2D transformation. An innite zoom in the texture is made possible by using a paper model based on multifrequency solid turbulence. Our results indicate a dramatic improvement over a static background.
