Rendition's Javascript interface allows a vastly more flexible rendering approach than the traditional linear sequence of frames taken from a 3D package.

Consider a product available in 20 colours, viewable from 10 locations, in 5 configurations. This amounts to 1000 possible images. It's easy to see how that number could rapidly get out of hand, as the number of possible modifications increases. 

Rendition allows you to control aspects of the scene programatically (using Javascript) - literally building the scene out of component geometry, materials and lights.

For example, given an XML specification of the required render image, Rendition can be programmed to fetch the relevent files, assemble the scene, and render the correct output image, though it may be one of a billion possibilities.
