A few high end tutorials for pushing Imagine to the limit. As always, a WIP, so still have more to add

*note - the link has been updated to the new website*

A collection of tutorials from the old days:

Templar
A catalogue of Sketch to 3D techniques

Giraffe
A metanurbs tutorial based on the Imagine fracture and smooth commands

Horse
An applique tutorial that turns a picture into a 3D model quickly and easily

Woman
Several techniques used to create a woman

Head
A slice and merge tutorial.

Leg(bones)
A demonstration object for IFW

A description of the settings in the Amiga versions of the Essence Textures- also available in French. (I thought that the FAWS site was in the Web Links section anyway, but can't seem to find it?)
Also contains various Objects and some tutorials.

A nice site with many brushmap patterns that you can use as wallpapers, carpets, furniture dressing and the likes... all tileable.

Personal website of Neil Blevins Pixar and former Blur Studios employee. in the CG education section there are many interesting articles on modelling, lighting, andrecreating materials such as brushed metal, glass, ceramics. Geared around 3ds Max and Brazil but much of it is applicable to Imagine.

Tips and tricks on how to postprocess your pictures to make them look really good

This nice site has some good art, SciFi based mostly, and quite a few free Bryce objects that can be converted to Imagine use.

I accidentally deleted this link, resubmitting it since it is very good.

Contains tutorial and sample code to create texture DLLs for the Win32 version of Imagine 3D, as well as a tutorial on the use of the shininess attribute on objects.

An add-on site for the PD 3D Astronomy program 'Celestia'.

A good source of brush-maps for real and fictitious planets, nebulae, moons etc.

Also, has a variety of real and sci-fi models in 3DS format- Star Trek, Babylon 5, 2001 etc.
