- A Simple Shading Example in OpenGL Shading Language
- Mar 10, 2006
- In this example, we apply a brick pattern to an object. The brick pattern is calculated entirely within a fragment shader. This example, like most of the others in this book, consists of three essential components: the source code for the vertex shader, the source code for the fragment shader, and the application code that initializes and uses these shaders. This chapter focuses on the vertex and fragment shaders.

- CUDA for Engineers: 2D Grids and Interactive Graphics
- Dec 21, 2015
- In this chapter from CUDA for Engineers: An Introduction to High-Performance Parallel Computing, you'll learn about the essentials of defining and launching kernels on 2D computational grids. The authors explain sample code, the flashlight app that takes advantage of CUDA/OpenGL interop to implement real-time graphical display and interaction with the results from 2D computational grids. Finally, they show how to use flashlight as a template and perform modifications to make it applicable to a real engineering problem, numerical exploration of dynamic stability.

- Drawing Primitives in OpenGL
- May 12, 2006
- Computer-generated animation in film and television, as well as state-of-the-art video games, features realistic water, fire, and other natural effects. Many people new to computer graphics are astounded to learn that these realistic and complex models are simple triangles and pixels as far as computer graphics hardware is concerned. In this chapter, OpenGL® Distilled covers the OpenGL primitive types and how to control their appearance with several basic rendering features.

- GPGPU: Is a Supercomputer Hiding in Your PC?
- Jul 1, 2005
- If you've played some of the latest, hottest video games, you've exercised your GPU in a traditional graphics sense. But other companies are now using the GPU non-traditionally, for general-purpose computation on a graphics processing unit (GPGPU). Why should you care? Because its lightning-fast, parallel computational capability makes for smooth, rich, vibrant graphics in today's games. And, repurposed, the GPU can help solve more serious problems (medical and financial) in the real world. Chris Seitz explains how.
