There's plenty of 2D graphics libraries out there, some 3D ones as well, but that hasn't stopped Jakob Westhoff from creating his own driver for the Image_3d package to allow for live 3D image browser rendering.
Quite some time ago my friend Kore Nordmann had a talk at our local PHP Usergroup about 3D rendering techniques which was quite inspiring. Shortly after that talk I decided to write a simple 3D renderer. But, hey there are so many of them already out there, that I decided to do something more unusual.
I just started over and began to write a ECMA Script based live 3D renderer for browsers which understand the new "canvas" tag. After some simple tests I realized that it would be quite cool to implement this as a driver for Kore's Image_3D package, which is entirely written in PHP.
Be sure to check out his post to see what this new driver makes possible. There's an image complete with controls to rotate, zoom, turn of its axis and export to both the SVG and PNG formats. Definitely work checking out!
