Texturing and Lighting with OpenGL and GLSL
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.
OpenGL Interoperability with CUDA
In this article I will discuss how you can use OpenGL textures and buffers in a CUDA kernel. I will demonstrate a simple post-process effect that can be applied to off-screen textures and then rendered to the screen using a full-screen quad. I will assume the reader has some basic knowledge of C/C++ programming, OpenGL, and CUDA. If you lack OpenGL knowledge, you can refer to my previous article titled Introduction to OpenGL or if you have never done anything with CUDA, you can follow my previous article titled Introduction to CUDA.
GPU Skinning of MD5 Models in OpenGL and Cg
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].
