5.3Using OpenGL

This section describes the PowerStorm OpenGL display driver, which is designed to optimize OpenGL performance on Compaq Professional Workstations. This section includes the following topics:

∙Using OpenGL Applications, for users running applications developed with OpenGL

∙Developing OpenGL Applications, for users developing OpenGL applications

For a more comprehensive discussion of the OpenGL interface, refer to the Microsoft Windows NT OpenGL documentation included in the Microsoft Windows NT version 4.0 Software Developer’s Kit (SDK).

5.3.1 Using OpenGL Applications

In addition to a generic OpenGL display driver, Windows NT OpenGL includes a mechanism by which OpenGL rendering can be performed by vendor-supplied display drivers. Compaq provides such an OpenGL display driver in the PowerStorm 300/350 Software product. This driver takes advantage of hardware features that improve rendering performance and quality, and is used with the PowerStorm 300 AGP or 300/350 PCI graphics controller.

When an application requests a pixel format, Windows NT OpenGL will satisfy the request with the pixel format that best fits the description. This pixel format can be one of the following:

∙A hardware pixel format, supported by the PowerStorm 300/350 OpenGL driver

∙A software pixel format, supported by the generic Windows NT OpenGL driver

5.3.2Developing OpenGL Applications on Intel Platforms

This section provides information for developing OpenGL applications that optimize the performance of PowerStorm 300 AGP graphics controllers on Intel platforms. If you have a PowerStorm 300/350 PCI graphics controller on a Windows NT Alpha platform, see Section 5.3.3 instead.

300 specifications

The Compaq 300, introduced in the early 1990s, marked a pivotal moment in personal computing, combining cutting-edge technology with user-centric design. This desktop system was targeted at both business professionals and home users, reflecting the growing demand for powerful yet affordable computing solutions.

One of the main features of the Compaq 300 was its robust Intel processor. It originally shipped with various configurations of Intel's 80486 microprocessor, which provided a significant performance boost over its predecessors. The 486 architecture enabled users to run more complex applications, enhancing productivity and making it suitable for tasks ranging from word processing to graphics editing.

In terms of memory, the Compaq 300 supported up to 16MB of RAM, which was substantial for its time, allowing seamless multitasking of programs. The system typically included a 120MB IDE hard drive, which facilitated ample storage for documents and software, a critical aspect for users who needed to manage large volumes of data.

The Compaq 300 featured an integrated graphics card based on the popular VGA standard, enabling clear display quality for applications and gaming. Notably, its 14-inch CRT monitor that accompanied the system offered crisp visuals and an optimal viewing experience for users.

Another characteristic of the Compaq 300 was its expandability. The desktop came equipped with several expansion slots, allowing users to easily add components such as sound cards, network cards, or additional storage drives. This feature provided users with the flexibility to upgrade their systems as technology evolved, ensuring longevity in a rapidly changing landscape.

The Compaq 300 also showcased advanced connectivity options for its time. It included multiple serial and parallel ports, providing versatile connectivity with peripherals like printers, scanners, and modems. This adaptability was crucial, especially as businesses began to integrate more technology into their operations.

Durability and reliability were hallmarks of Compaq's design philosophy, and the Compaq 300 was no exception. Its solid construction and dependable components appealed to users who required a trustworthy system for daily tasks.
