Tobias Schlitt has a new post with a proposal for inclusion into the PEAR libraries - PEAR::Image_3D.

Image_3D enables you to render 3D images using PHP. As I mentioned in my last post on that topic, the usage of PHP to render 3 dimensional images seems a bit ridiculous, but it definitly has a sense: Imagine the rendering of 3D charts from database data (we plan to implement a driver for PEAR::Image_Graph) or rendering of simple 3D images from user data. Of course one should not render those images on the fly, but cache them. Exciting is the fact, that rendering even complex 3D images (about 16.000 polygones) takes an acceptable amount of time. Try it yourself! :)

He also shares a few resources on the subject, including: the proposal, the package itself, as well as an example of it in use...
