copied!<p>I spent some time reading the docs and playing with it. As a test I made a Conway's Game of Life using their canvas object:</p> <p><a href="http://o3d-life.googlecode.com/svn/trunk/life_colors.html" rel="nofollow noreferrer">life</a></p> <p>This is actually running completely in javascript and performs surprisingly well; much faster than an equivalent test I did in Unity3D. Moving it into a pixel-shader would be the next step in performance, then it would really fly.</p> <p>This is a serious project on the cutting edge of graphics technology. They have made really good decisions about the architecture and how it integrates with the browser. </p> <p>But, it is a low level graphics api - at a similar level to DirectX or OpenGL, and it uses a modern 'programmable pipeline' instead of a traditional/legacy 'fixed-function-pipeline'. In layman's terms, this means that it wont run on older computers, but it can fully utilize newer graphics hardware in terms of both performance and features. It also means that developers need to understand modern graphics programming techniques like shaders, render graphs, etc.</p> <p>It supports web-formats for images (like jpg and png) but also supports game-industry style DDS textures that are far more optimized for loading into video card RAM. It can load xml-based COLLADA assets, but also has a binary-like JSON interface for optimized loading of processed assets.</p> <p>For O3D to really take off, it is going to need higher-level javascript APIs built on top of it. Ideally something like a game engine that includes physics and audio, has a consistent lighting model and optimized asset format.</p>
