A professional 3D-modeling plus raytracing and animation system. Features include a multi-window graphical user interface, 3D modeling and objects, materials assignments, preview functions, animation, particle systems, and raytracing.

An ambitious project to create a feature rich, extensible 3D modeling environment. Currently emphasizes povray export for scene rendering, but support for other formats are planned. Program will eventually include a native ray tracer as well.

A 3D rendering application to generate photo-realistic models and 3D images, based on the LightWorks rendering engine. Seven levels of rendering: flat, Gouraud, Phong, preview z-buffer, full z-buffer, preview ray-trace, and full ray-trace.

SensAble's modeling system allows designers to model on the computer with their sense of touch. The system provides a physical, analog interface to create a valuable, digital asset.

A modeling application to design wireframe, polygonal, and hybrid objects with special attributes, test, and save 3D models for real-time rendering.

GUL - Geometry Utility Library for construction, evaluation, manipulation and visualization of geometric objects, especially for parametric and implicit defined surfaces.

An Opensource 3D modeling application based on Cybersculpt a 3D modeling application for the Atari ST range of computers. Creates models using translational and rotational sweeps of polylines.

Tutorials for Rhino3d covering general setup, the RIB-file, parameterization and texture maps, applying shaders to objects, smoother NURBS, texture control, and a gallery. Also BMRT benchmark and a few shaders.

Open source 3D-patch modeler and animation tool designed to model and animate "organic" shapes such as humans, animals, and aliens. It is written in Java, and outputs to POV-Ray and RenderMAN format.

Free 3D designing and modeling program for Windows. Can extrude/sweep new objects, and use parametric NURBS curves. Old version includes full Visual Basic plus Assembly source code. Product specifications, screenshots, tutorials, and downloads.
