Intergraph announces RenderGL, first graphics library to enable "Real-Time Reality" on the desktop.
RenderGL, which runs on top of OpenGL, can accelerate the rendering of models with realistic features such as Phong-shading, bump maps, 3D texturing and shadows up to 16 times faster than workstations using OpenGL alone. The ability to display this level of photorealistic-image quality in real time defines "Real-Time Reality(TM)."
Intergraph introduced RenderGL in conjunction with the announcement of its next-generation TDZ Workstations, which incorporate Intergraph's new high-performance RealiZm 3D Graphics subsystem (see separate TDZ June 25 announcement). RenderGL is an integral element of RealiZm 3D Graphics, which also includes the first hardware graphics accelerators to achieve greater than 1 million triangles per second on Windows NT.
"RenderGL is a giant step toward rendering feature-length animated films, such as `Toy Story,' in a day," said Wade Patterson, president of Intergraph Computer Systems. "RenderGL enables creative and technical professionals -- for the first time -- to add more sophisticated photorealistic effects, such as bump maps and shadows, to 3D models and then to render those models at accelerated speeds, producing what we term Real Time Reality."
Enhancing the OpenGL Standard
RenderGL extends OpenGL's capabilities by accelerating the generation of photorealistic 3D images. It is an open library available for use by any OpenGL-based software application. In addition, RenderGL has an associated software developers kit (SDK), which allows software developers to take advantage of RenderGL's performance and realism-enhancing features in their OpenGL-based applications.
"Any vendor can easily enhance existing or design new software to take advantage of RenderGL, and we think many of them will," said Patterson. "Already, three industry-leading graphics software vendors plan to support RenderGL: Softimage, maker of SOFTIMAGE 3D; NewTek, maker of LightWave 3D; and MetaTools, maker of Kai's Power Tools."
"These vendors obviously recognize the impact that RenderGL, and RealiZm 3D Graphics as a whole, will have on the industry," said Jeff Edson, vice president of Intergraph's Digital Media Group. "If you can design your animation in Real-Time Reality -- at accelerated speeds with a photorealistic quality that represents what your final product will be -- you can work a lot faster, and you have a lot more time to be creative. Ultimately, these are the benefits of RenderGL and RealiZm: higher-quality animations produced in a shorter amount of time."
Photorealistic Features for Real-Time Reality
RenderGL works on top of OpenGL to enable very fast rendering
of high-quality, photorealistic features that are not
accelerated by OpenGL. These features include Phong shading.
Phong shading uses a much higher quality, and therefore a much
more demanding shading algorithm than Gouraud shading.
Bump mapping. Bump mapping is used to provide superbly textured
surfaces on 3D models. Bump maps are applied to deflect light
in numerous directions to make the surfaces appear "bumpy,"
thereby providing a more realistic texture.
Procedural 3D textures. Procedural textures, or 3D textures,
are textures that occupy three dimensions and understand the
the geometry of the object to which they are applied. For
example, if a 3D texture of wood is applied to a block, a
cross-sectional view of the block will reveal the grain of the
Shadows. RenderGL provides special extensions for the
acceleration of shadows, enabling RealiZm graphics to display
shadowed objects dramatically faster than standard OpenGL-based
RenderGL, an integral element of Intergraph's RealiZm 3D graphics within the new TDZ-310, TDZ-410 and TDZ-610 workstations, will be shown publicly for the first time at SIGGRAPH `96 in New Orleans and will be available in August.
