Autodesk® MatchMover™ is a camera tracking application that automatically captures 3D camera path and camera parameters from 2D video and film image sequences. After capturing a 3D camera path with MatchMover, you can export the camera data to a number of file formats supported by 3D animation or compositing programs. This allows you to work with the camera data in your favorite animation or compositing application to accurately place 3D objects into a video or film sequence. Providing a straightforward and cost-effective way to mix 2D live-action footage with 3D animation and special effects, MatchMover allows you to take advantage of the 2D world of film and the 3D world of animation.

Blender is a free and open source 3D animation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation. Blender is well suited to individuals and small studios.

xNormal is an application to generate normal / ambient occlusion / displacement maps. It can also project the texture of the highpoly model into the lowpoly mesh ( complete texture transfer, even with different topologies ). It includes too an interactive 3D viewer ( with advanced shaders and realtime soft shadows / glow effect ), some Photoshop filters and importers/exporters for 3dsmax and Maya. It supports high levels of parallelism using multicore/multithreading, distributed/parallel rendering, ray tracing and advanced GPGPU techniques.

The NVIDIA Normal Map filter creates normal maps from grayscale height maps. The filter UI provides a powerful 3D preview and a variety of filtering options. For MIP-mapped normal maps, the NormalMap Filter should be used for preview only, and then the grayscale map exported via the DDS plugin with "Normal Map Settings..." enabled. This will create a normal map with maximal detail and fidelity for all texture levels, without undesirable filter aliasing.

Anim8or is a 3D modeling and character animation program. While it is far from a complete professional level application like 3DStudio MAX or Maya, it has enough capability to be of use to others.

Art of Illusion is a free, open source 3D modelling and rendering studio. Many of its capabilities rival those found in commercial programs. Highlights include subdivision surface based modelling tools, skeleton based animation, and a graphical language for designing procedural textures and materials.

Take the hard work out of modelling plants. PlantStudio Botanical Illustration Software is a tool for creating 3D plant models and 2D illustrations. PlantStudio simulates flowers, vegetables, weeds, grasses, and herbs using a simulation of growth and structure.

The Persistence of Vision Raytracer is a high-quality, Free Software tool for creating stunning three-dimensional graphics.

Wings 3D is an advanced subdivision modeler that is both powerful and easy to use. Wings 3D offers a wide range of modeling tools, a customizable interface, support for lights and materials, and a built-in AutoUV mapping facility.

You can make gray-anaglyph, color-anaglyph, interleave image for LC-shutter glasses, images for SHARP 3D-LC Display.
