This application uses both the X Windows and OpenGL libraries to quickly and accurately render 3D images In addition, CATweb Navigator V2.0 and above has been enhanced to effectively exploit the capabilities of XVFB and DSO. 8.5 OpenGL Enhancements The following section describes the enhancements to OpenGL. 8.5.1 OpenGL 64-bit Indirect Rendering (4.3.1) In AIX 4.3.1, OpenGL has added 64-bit support for indirect rendering. To use this function, a new level of the xlc++ compiler is required. See /usr/lpp/OpenGL/README for more information. 8.5.2 OpenGL Performance Enhancements (4.3.2) IBM OpenGL Versions 1.1 and 1.2 are enhanced to improve performance in several areas. Users of uniprocessor systems will note faster drawing of primitives under most conditions. All users should see improvements in: • Throughput and cache utilization • Latency when lighting is enabled • Overall performance on any primitives using the new MultiDrawArray extension 8.5.3 OpenGL Version 1.2 and ZAPdb (4.3.2) OpenGL Version 1.2, released on March 16, 1998, is the second revision since the original Version 1.0. OpenGL within AIX Version 4.3.2 is enhanced to support OpenGL Version 1.2. Several additions were made to the graphics library (GL), especially to the texture mapping capabilities and the pixel processing pipeline. Following are brief descriptions of each addition: • Three-Dimensional-Texturing Three/dimensional textures can be defined and used. In-memory formats for the three-dimensional images, and pixel storage modes to support them, are also defined. One important application of three-dimensional texture is rendering volumes of image data. • BGRA Pixel Formats BGRA extends the list of host-memory color formats. Specifically, it provides a component order matching file and framebuffer formats common on Windows platforms. • Packet Pixel Formats Packed pixels in host memory are represented entirely by one unsigned byte, one unsigned short, or one unsigned integer. The fields with the packed pixels are not proper machine types, but the pixel as a whole is. Thus the pixel storage modes and their unpacking counterparts all work correctly with packed pixels. • Normal Rescaling Normals may be rescaled by a constant factor derived from the modelview matrix. Rescaling can operate faster than renormalization in many cases, while resulting in the same unit normals. 228 AIX Version 4.3 Differences Guide
• Separate Specular Color Lighting calculations are modified to produce a primary color consisting of emissive, ambient, and diffuse terms of the usual GL lighting equation, and a secondary color consisting of specular terms. Only the primary color is modified by the texture environment; the secondary color is added to the result of texturing to produce a single post-texturing color. This allows highlights whose color is based on the light source creating them, rather than the surface properties. • Texture Coordinate Edge Clamping GL normally clamps such that the texture coordinates are limited to exactly the range [0,1]. When a texture coordinate is clamped using this algorithm, the texture sampling filter straddles the edge of the texture image, taking half its sample values from within the texture image, and the other half from the texture border. It is sometimes desirable to clamp the texture without requiring a border, and without using the constant border color. A new texture clamping algorithm, CLAMP_TO_EDGE, clamps texture coordinates at all mipmap levels such that the texture filter never samples a border texel. The color returned when clamping is derived only from the edge of the texture image. • Texture Level of Detail Control Two constraints related to the texture level of detail parameter λ (lambda) are added. One constraint clamps λ (lambda) to a specified floating point range. The other limits the selection of mipmap image arrays to a subset of the arrays that would otherwise be considered. Together, these constraints allow a large texture to be loaded and used initially at low resolution and to have its resolution raised gradually as more resolution is desired or available. Image array specification is necessarily integral rather than continuous. By providing separate, continuous clamping of the λ (lambda) parameter, it is possible to avoid popping artifacts when higher resolution images are provided. • Vertex Array Draw Element Range A new form of DrawElements that provides explicit information on the range of vertices referred to by the index set is added. Implementations can take advantage of this additional information to process vertex data without having to scan the index data to determine which vertices are referenced. Because OpenGL 1.2 is a superset of OpenGL 1.1, all programs written for OpenGL 1.1 run on OpenGL 1.2 without modification, recompiling, or relinking. OpenGL 1.2 support is available in AIX 4.3.2 only on the GXT3000P PCI Graphics Accelerator. Users of other graphics adapters are limited to functions contained in OpenGL 1.1 and OpenGL 1.1 extensions. The optional Imaging Extension subset is not supported by the IBM OpenGL 1.2 implementation (at this time). The ZAPdb interactive OpenGL debugger is enhanced to support all new features provided in OpenGL Version 1.2. Graphical Environment Enhancements 229
