In this article, I will introduce the reader to CUDA 5.0. I will briefly talk about the architecture of the Kepler GPU (Graphics Processing Unit) and I will show you how you can take advantage of the many CUDA (Compute Unified Device Architecture) cores in the GPU to create massively parallel programs.
In this article I will demonstrate how to implement a basic lighting model using the Cg shader language. If you are unfamiliar with using Cg in your own applications, then please refer to my previous article titled Introduction to Shader Programming with Cg 3.1.
This article is an updated version of the previous article titled Transformation and Lighting in Cg. In this article, I will not use any deprecated features of OpenGL. I will only use the core OpenGL 3.1 API.
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.
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. Another method of rending primitives in OpenGL uses vertex arrays. And finally I will also examine the use of display lists to generate a set of render calls that can be executed at another point in time. The reader is expected to have a basic understanding of programming techniques in C++. If you want to know how you can get started with OpenGL, you can refer to my previous article titled [Introduction to OpenGL].
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. I assume that the reader is familiar with the C/C++ programming languages. I will use Microsoft Visual Studio 2008 to show how you can setup a project that is compiled with the OpenCL API.
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.
In this article, I will give a brief introduction to using NVIDIA’s CUDA programming API to perform General Purpose Graphics Processing Unit Programming (or just GPGPU Programming). I will also show how to setup a project in Visual Studio that uses the CUDA runtime API to create a simple CUDA program.
This article will step you through the process of getting started with XNA. I will show how to setup a new project using XNA Game Studio. This article is the basis for the following articles regarding XNA development.
In this article, I will show how to implement projective shadow mapping in OpenGL using Cg shaders.
The basis of this post comes from the article titled [Transformation and Lighting in Cg]. I will assume the reader has a basic understanding of OpenGL and already knows how to setup an application that uses OpenGL. If you require a refresher on setting up an application using OpenGL, you can refer to my previous article titled [Introduction to OpenGL for Game Programmers].
I will take advantage of a few OpenGL extensions such as GL_ARB_framebuffer_object to create a offscreen framebuffer to render to and and GL_ARB_texture_border_clamp for clamping to the border color of the projective textures.
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. Before reading this article, you should have a basic understanding of OpenGL and you should know how to setup a Cg shader. For a review on OpenGL, you can refer to my previous article titled [Introduction to OpenGL for Game Programmers] and to learn how to incorporate Cg shaders in your own applications, you can refer to my article titled [Introduction to Cg Runtime with OpenGL].
