Volumetric textures, introduced by Kajiya and Kay in 1989,
aims at modeling complex geometries by creating a
`volumetric skin' in the neighborhood of a surface.
This skin is composed of a repeated and deformed pattern,
as it is for a classical texture.
We have transformed this expensive method designed to model fur
into a general, user-friendly and efficient tool, that is able to
model, animate and render complex repetitive geometries
such as foliage, grass, forest, fur, etc...
Our representation is volumetric, multiscale, and encodes
a reflectance function in each voxel.
This allows us to use only the information that is necessary to obtain an
image. This one is thus computed quickly and without aliasing,
using a single ray per pixel.
We show also how to convert existing representations into volumes,
how to map volumetric textures,
and how to integrate the rendering into the standart ray-tracing algorithm.
