Overview of this book

OpenGL is the leading cross-language, multi-platform API used by masses of modern games and applications in a vast array of different sectors. Developing graphics with OpenGL lets you harness the increasing power of GPUs and really take your visuals to the next level. OpenGL Development Cookbook is your guide to graphical programming techniques to implement 3D mesh formats and skeletal animation to learn and understand OpenGL. OpenGL Development Cookbook introduces you to the modern OpenGL. Beginning with vertex-based deformations, common mesh formats, and skeletal animation with GPU skinning, and going on to demonstrate different shader stages in the graphics pipeline. OpenGL Development Cookbook focuses on providing you with practical examples on complex topics, such as variance shadow mapping, GPU-based paths, and ray tracing. By the end you will be familiar with the latest advanced GPU-based volume rendering techniques.

While simple demos and applications can get along with basic primitives like cubes and spheres, most real-world applications and games use 3D mesh models which are modelled in 3D modeling software such as 3ds Max and Maya. For games, the models are then exported into the proprietary game format and then the models are loaded into the game.

While there are many formats available, some formats such as Autodesk® 3ds and Wavefront® OBJ are common formats. In this chapter, we will look at recipes for loading these model formats. We will look at how to load the geometry information, stored in the external files, into the vertex buffer object memory of the GPU. In addition, we will also load material and texture information which is required to improve the fidelity of the model so that it appears more realistic. We will also work on loading terrains which are often used to model outdoor environments. Finally, we will implement a basic particle system for simulating fuzzy phenomena such...
