Abstract:
|
Rendering detailed animated characters is a
major limiting factor in crowd simulation. In
this paper we present a new representation
for 3D animated characters which supports
output-sensitive rendering. Each character
is encoded through a small collection of textured boxes storing color and depth values. At runtime, each box is animated according to the rigid transformation of its associated bone. A fragment shader is used to recover the original geometry using an adapted version of relief mapping. Unlike competing outputsensitive approaches, our compact representation is able to recover high-frequency surface details and reproduces view-motion parallax. Furthermore, our approach does not require
us to predefine the animation sequences nor
to select a subset of discrete views. Our user study demonstrates that our approach allows for much more simulated agents with negligible visual artifacts. |
