WebGL

WebGL is a cross-platform, royalty-free web standard for a low-level 3D graphics API based on OpenGL ES 2.0. WebGL is exposed through the HTML5 Canvas element as Document Object Model interfaces. Allowing developers familiar with OpenGL ES 2.0 to easily understand and recognize WebGL as a Shader-based API using GLSL, with constructs that are semantically similar to those of the underlying OpenGL ES 2.0 API. The WebGL API stays very close to the OpenGL ES 2.0 specification, with some concessions made for what developers expect out of memory-managed languages such as JavaScript.

WebGL is released as a free and open-source web standard.
