Procedural texture particles

We introduce procedural texture particles, a new texture model at mid-way between procedural textures and example-based texture synthesis. As for example-based texture synthesis, we use an input example to produce similar looking textures. But instead of creating texture images (pixel arrays), our textures are defined in the form of procedural distributions of interchangeable visual elements called particles. As for classical example-based synthesis, our method guarantees a certain visual resemblance with the example, but obtained textures are compact and defined on the entire infinite 2D plane.
