SGI and the OpenGL Architecture Review Board (ARB) today announced the availability of the OpenGL 1.3 specification. OpenGL 1.3 implementations are expected to be available for various platforms later this year. The OpenGL graphics system specification allows developers to incorporate a broad set of rendering, texture mapping, special effects and other powerful visualization functions and provides a graphics pipeline that allows unfettered access to graphics hardware acceleration. In OpenGL 1.3, several additional features and functions have been ratified and brought into the API's core functionality. These core features enhance OpenGL in the following ways:

  • Cube map texturing—for higher quality environment mapping and lighting support

  • Multisampling—for order-independent anti-aliased rendering of points, lines and polygons

  • New texture modes that provide more powerful ways of applying textures to rendered objects:

    1. Texture Add Environment mode

    2. Texture Combine Environment mode

    3. Texture Dot3 Environment mode

    4. Texture Border Filtering mode

  • Compressed texture framework—to allow higher quality textures in less memory regardless of file format
