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.

Implementing transfer function for volume classification


In this recipe, we will implement classification to the 3D texture slicing presented before. We will generate a lookup table to add specific colors to specific densities. This is accomplished by generating a 1D texture that is looked up in the fragment shader with the current volume density. The returned color is then used as the color of the current fragment. Apart from the setup of the transfer function data, all the other content remains the same as in the 3D texture slicing recipe. Note that the classification method is not limited to 3D texture slicing, it can be applied to any volume rendering algorithm.

Getting ready

The code for this recipe is in the Chapter7/3DTextureSlicingClassification directory.

How to do it…

Let us start this recipe by following these simple steps:

  1. Load the volume data and setup the texture slicing as in the Implementing volume rendering using 3D texture slicing recipe.

  2. Create a 1D texture that will be our...
