3D on the Web in 2011
Chad Austin discusses the current state of 3D graphics on the web. He outlines technologies like WebGL, Flash 11, Unity3D and Silverlight that enable 3D in browsers. WebGL provides full programmability via OpenGL ES 2.0 but lacks support in some browsers. Flash 11 exposes 3D via ActionScript but has shader limitations. Unity3D uses a plugin for 3D games but not full hardware access. Security is a challenge as 3D exposes vulnerabilities in graphics drivers. Chad predicts WebGL will become dominant long term as browsers support it.
