Texturing and Lighting with OpenGL and GLSL

OpenGL GLSL Texturing and Lighting

OpenGL GLSL Texturing and Lighting

In this article I will demonstrate how to apply 2D textures to your 3D models. I will also show how to define lights that are used to illuminate the objects in your scene.
I assume that the reader has a basic knowledge of C++ and how to create and compile C++ programs. If you have never created an OpenGL program, then I suggest that you read my previous article titled [Introduction to OpenGL and GLSL] before continuing with this article.

Introduction to Shader Programming with Cg 3.1

NVIDIA Cg

NVIDIA Cg

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 article does not explain how use OpenGL. If you require an introduction to OpenGL, you can follow my previous article titled Introduction to OpenGL.

Bob with Lamp (GPU Skinning)

This tutorial builds upon the previous article titled [Loading and Animating MD5 Models with OpenGL]. It is highly recommended that you read the previous article before following this one. In this tutorial, I will extend the MD5 model rendering to provide support for GPU skinning. I will also provide an example shader that will perform the vertex skinning in the vertex shader and do per-fragment lighting on the model using a single point light. For a complete discussion on lighting in CgFX, you can refer to my previous article titled [Transformation and Lighting in Cg].
