Fast computation of seamless video loops.
This tool quickly computes a 5-second looping video from a non-looping input video.
Demo (v1.0 2015-10-25; v1.1 2015-11-12) |
|
Automated video looping with progressive dynamism.
Tool to extract a 5-second looping video from a non-looping input video.
Also a viewer application to enable both interactive control over the level of dynamism of the output video,
as well as manual editing of which regions are animated or static.
Demo (v1.0 2013-11-21; v2.0 2014-03-28) |

Cliplets: Juxtaposing still and dynamic imagery.
This tool creates cinemagraphs and more general spatiotemporal compositions
from ordinary handheld video.
project-page demo |
|
Random-access vector graphics.
Antialiased vector graphics rendered on arbitrary surfaces or under arbitrary deformations.
We create a coarse lattice in which each cell contains a variable-length encoding of the
graphics primitives that overlap it.
These cell-specialized encodings are interpreted at runtime within a pixel shader.
Demo (v1.0 2008-06-13; v1.1 2014-09-02 bug fixes) |
|
Rendering of terrains using geometry clipmaps.
Terrain rendering using a set of nested regular grids.
The terrain is either incrementally decompressed from a compact in-memory representation or
synthesized on the fly as a user navigates within an infinite landscape.
