SGI announces OpenGL 1.4
By ron carlson, Insanely Great Mac
July 15th 2002
New features, functionality arrive with latest dot update of the industry standard
Designing the next-generation sports car, creating a must-have game, training future
fighter pilots or producing the next blockbuster movie will become easier with the
latest version of the OpenGL application programming interface (API). SGI and the
OpenGL Architecture Review Board (ARB) have announced the availability of the OpenGL
1.4 specification. Introduced 10 years ago by SGI, OpenGL is the graphics standard
used by all Macs produced in recent years.
"We are proud of the global acceptance OpenGL has earned in its 10-year history, as
evidenced by the broad range of hardware vendors and independent software vendors that
rely on its cross-platform functionality and depth of graphics quality. We are also
pleased that the ARB is delivering on its intention to provide a new specification
every year, and OpenGL 1.4 is the latest proof point," said Shawn Underwood, director
of marketing, SGI.
OpenGL 1.4 new features:
� Depth textures and shadow textures, enabling real-time shadows and related
image-based rendering techniques;
� Vertex programming framework, setting the stage for user-defined geometry, lighting
and shading programs and enabling high-level general-purpose shading languages;
� Automatic texture mipmap generation, providing rapid updates and high-quality
texture filtering for dynamic textures;
� Numerous smaller enhancements -- multiple draw arrays, for higher geometry
throughput; window raster position, for precise 2D and image rendering; user-defined
fog coordinate, for advanced fog effects; user-defined secondary color, point
parameters, texture; level-of-detail bias, texture crossbar, and new frame buffer;
blending modes and stenciling functions for more flexible shading; and rendering
effects.
With more than 60 hardware developer licensees, OpenGL has the broadest industry
support of any openly licensed graphics API. OpenGL 1.4 implementations are expected
to be available for various platforms later this year.
