OpenGL: Information and Resources

OpenGL stands for Open Graphics Library and is an open source library of over 250 function calls that are compatible across multiple platforms and languages. OpenGL can be used to draw complex two dimensional and three dimensional objects for use in simulators and video games. In addition, OpenGL is used in scientific simulations such as climate models as well as CAD and virtual reality applications. OpenGL is a specification at its simplest explanation – meaning it defines a set of functions that can be implemented by various programs, systems, and hardware that must meet certain requirements to use and implement OpenGL API.

OpenGL Tutorials and Resources:

A basic OpenGL tutorial with examples

This site lists examples and tutorials for use when learning the OpenGL API; includes a list of sites for advanced and novice users alike.

How to use the led Shader in OpenGL.

The GLUT enables the construction of a true window independent system.

OpenGL is maintained and supported by the non-profit open source group known as the Khronos Group.

Standards for the OpenGL API and graphics creation using them.

The OpenGL API has two main purposes for which it was created. One is to provide a single and consistent interface to programmers for interfacing with multiple different 3D accelerators. This is an attempt to hide the complexities of interfacing across multiple different platforms and languages. OpenGL also enables cross hardware specification by requiring that hardware support the full specifications of the OpenGL. This way all hardware that supports OpenGL supports all of the OpenGL reducing workarounds and additional time taken to find problems with unsupported parts of OpenGL.

OpenGL has proven to be an invaluable tool for game and simulation developers and continues to be an accepted standard of hardware, software, and APIs everywhere. Graphics processors and cards for consumer products have initiated support for development projects. Companies like NVIDIA and Macintosh have embraced the OpenGL API and combined it with other specifications like DirectX. With each new edition or version, OpenGL is supported by more vendors and used by more applications and hardware companies around the globe. Improvements continue in object models, pixel buffering, shader indexes, as well as the tools and utilities for the OpenGL API.

I am an online writer and soon to be published author. I grew up in Southern California, but I currently live in the Bay Area while I work on my books. I enjoy camping and hiking with my dog Max or just relaxing on the back porch while I write. Stay tuned for my first children’s book to be released about Max.
