Images

Theses images were rendered on a Silicon Graphics workstation by a small software I designed during my Bachelor of Science to demonstrate how to render in real-time procedural textures using only OpenGL primitives. This software enables you to change interactively all the parameters of the texture and shows the resulting texture applied on a 3D model. It is fluid on a Onyx II workstation: from a few dozen frames per second for a simple 3D model (the cube) to a few frames per second for a complex 3D model (the rabbit designed with 70000 triangles).

This software is a simple interactive layer; it relies on the small GLP Library - also designed during my Bachelor of Science - to do the actual rendering.

Data files

All 3D models are in the simple text .m format: first comes a vertices lists followed by a triangle list. Here are the .m models used in the above images:

• The very simple cube.
• The rabbit (gzip-compressed) features has 34835 vertices and 69473 triangles and is provided courtesey of Marc Levoy, Stanford University.

The texture parameters are stored by the software in a very simple human-readable text format. Theses parameters reflects the paramteres defined by the GLP Library used for the rendering. Here are the textures used in the above images:

• Agate.
• Marbre.
• Wood.
• Pyjamas.
