O3D Section

O3D is a Javascript API designed by Google Labs to support high-end 3D hardware capabilities already present in most computers and bring them to your personnal web browser.
Please, install the O3D plug-in by visiting Google Labs before clicking the links below.

Tests are run on Firefox 3.5.1, Internet Explorer 8 and Chrome 2.0.172.37

PatAPI

The PatAPI is a little addition to the O3D API. You can find the sources here.
It's currently featuring :

System Helpers

_ Small hierarchy helpers to deal with O3D render nodes & transform nodes
_ A simple camera manipulation helper to move around the scenes using standard MAYA (i.e. targeted) or UnrealEd (i.e. first person) motion
_ A post-process chain helper that alleviates the setup of post-process passes
_ A "scene override" that helps render an entire scene into a specific buffer using a single override material (e.g. Depth pass, shadow mapping)
_ An Effects Manager that allows you to use the #include directive in your shaders and also manages the concept of "shader interfaces"
_ A Material Translator helper that substitutes override effects to existing materials based on regular expression matches and also translates shader parameters to ensure compatibility and correct initialization
_ A "minipack" helper to handle subsets of O3D objects within the actual O3D pack (helps to unload a single scene without hindering the more general objects)

Rendering

_ An implementation of the Reinhard tone mapping operator to support HDR scenes
_ An implementation of the Preetham skylight model for nice environmental scenery
_ An example of aerial perspective
_ An example of streamed terrain

... And lots of other stuff to come !
