Tao, a 3D dynamic document description language

Tao Presentations uses a dialect of the XL programming language to describe interactive multimedia 3D documents. This approach makes it easy to create 3D contents that can be used to present information, to visualize scientific data or to explore stereoscopic or auto-stereoscopic effects rapidly. The demands of an interactive, real-time environment have created a number of interesting challenges for us to solve, ranging from language expressiveness and document semantics to graphics performance and rendering quality.
