RenderMan isn't a 3D modeling application. Instead, it fleshes out animation to make it more realistic with interactive lighting and shading. Not only is it used for Pixar films, it's also the industry standard for special effects. To use it, you will need to create a 3D model or animation to render. RenderMan currently supports Autodesk's Maya (which has a free trial available for download) and The Foundry's Katana.
“The latest release of RenderMan is a technological reinvention. It’s the result of focused research and development at both Pixar and Disney, and these advancements are now freely available to the visual effects and animation community through Non-Commercial RenderMan.” said Ed Catmull, President of Pixar and Walt Disney Animation Studios. “We look forward to seeing what our users create.”Pixar has also launched a community site, which allows users to share creations and tips. You can download the free RenderMan here, and check out the video above to see RenderMan in action.Rachel Paxton-Gillilan is a freelance writer. You can find her on Twitter @rachpax.
