In this article I will demonstrate how to implement a basic lighting model using the Cg shader language.

In this article I will introduce the reader to shader programming using the Cg shader programming language. I will use OpenGL graphics API to communicate with the Cg shaders. This …

In this article, I will discuss how to use vertex buffer objects. This article discusses the ARB_vertex_buffer_object extension in detail.

In this article I will talk about OpenGL extensions. Every extension is defined by an extension specification. I will explain how to read the extension specification so that you will …

This article show how you can use the fixed-function pipeline in OpenGL to render lit objects with texturing.

In this article, I will examine multiple methods for rendering primitives in OpenGL. The first method I will look at is using immediate-mode rendering to render simple primitives in 3D. …

In this article I will provide a brief introduction to OpenCL. OpenCL is a open standard for general purpose parallel programming across CPUs, GPUs, and other programmable parallel devices.

In this article I will discuss how you can use OpenGL textures and buffers in a CUDA kernel.

This article demonstrates how to implement projected shadow maps in OpenGL using the Cg shader language.

In this article, I will discuss a technique called normal mapping. Normal mapping is a shader technique that encodes pre-computed surface normals in a texture that can be used to add extra detail to a surface without the requirement of adding extra geometry.
