HP Workstation zx6000 HP OpenGL Implementation Guide for HP-UX 11.X (IPF versi - Page 5

1 overview of OpenGL OpenGL is a hardware-independent application programming interface (API) that provides an interface to graphics operations. HP's implementation of OpenGL converts API commands to graphical images via hardware and/or software functionality. The information in this manual is valid only for OpenGL on IPF. For information on OpenGL on PA-RISC, refer to the PA-RISC version of the OpenGL Implementation Guide. introduction The OpenGL interface consists of a set of commands that allow applications to define and manipulate three-dimensional objects. The commands include: ■ geometric primitive definitions ■ viewing operations ■ lighting specifications ■ primitive attributes ■ pipeline control ■ rasterization control OpenGL has been implemented on a large number of vendor platforms where the graphics hardware supports a wide range of capabilities (for example, frame buffer only devices, fully accelerated devices, devices without a frame buffer, and so on). For more information on OpenGL, refer to these documents, published by Addison-Wesley and shipped with HP's implementation of OpenGL: ■ OpenGL Programming Guide Instruction on programming in OpenGL, offered in a tutorial format. ■ OpenGL Reference Manual A reference that contains details on all standard OpenGL functions, as well as utility (GLU) functions and X Window (GLX) functions. ■ OpenGL Programming for the X Window System Instruction on interfacing OpenGL with the X Window system. the OpenGL product This section provides information about HP's implementation of the OpenGL product, as well as information about the standard OpenGL product.
