The Utah 3D Animation Repository |
Introduction
In the last few years, ray tracing has become a viable option for interactive applications; however, this usually includes only interactive walkthroughs of static scenes, or simple rigid-body animation. Since more and more people are now interested in investigating efficient techniques for ray tracing dynamically animated scenes, we have decided to set up a repository for animations, similar to the Stanford 3D scanning repository for large scanned meshes.Currently, this page lists only animation sequences that have been prepared at the University of Utah, in both SCI Institute and school of computing. All models are given in obj format (which we perceive as the most simple of the more common geometry formats), with a separate obj file for each keyframe.
If you have interesting models to contribute to this site, let us know (email). If you want to use these animations for reseach projects or other noncommercial purposes, you are free to use them (though some acknowledgement would be nice).
Enjoy,
Ingo
AEK-24-cell
|
Description An animation of a "stereographic projection of a rotating tesseract (a type of 4-d convex polytop)". The code to generate this animation was written and donated by Andew Kensler (SCI Institute, University of Utah), and is included below. |
Ben
|
Description A model from "poser", running. |
UNC Exploding Dragon
|
Description The "UNC Exploding Dragon", an animation showing a pretty hard bunny falling onto a pretty brittle dragon and shattering it to pieces ... The model is part of the UNC dynamic model benchmark (http://gamma.cs.unc.edu/DynamicB/), and was first used in the following paper "Ray Tracing Dynamic Scenes using Selective Restructuring", Sung-eui Yoon, Sean Curtis, and Dinesh Manocha. Eurographics Symposium on Rendering 2007. |
Fairy Forest
|
Description
A fairy and a dragonfly, dancing through a
forest. The background is a pre-lighted environment texture, the fairy
and dragonfly are both animated meshes.

Marbles
|
Description
A hard-body simulation of some marbles falling into an (invisible) container.

AEK-Tesseract
|
Description An animation of a "stereographic projection of a rotating tesseract (a type of 4-d convex polytop)". The code to generate this animation was written and donated by Andew Kensler (SCI Institute, University of Utah), and is included below. |
Toasters
|
Description
A set of fidgeting wind-up toys (called "toasters") runnig around,
bumping into each other, and jumping over each other. |
Wood Doll
|
Description A simple wood-doll model. Only rigid-body animation, and only few triangles, but looks nice. |
