Dynamic Canvas for Non-Photorealistic Walkthroughs
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 field induced by the 3D displacement is matched using purely 2D transformations. The motion field 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 infinite 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.
