OpenGL Data Visualization Cookbook

Chapter 4. Rendering 2D Images and Videos with Texture Mapping

In this chapter, we will cover the following topics:

• Getting started with modern OpenGL (3.2 or higher)
• Setting up the GLEW, GLM, SOIL, and OpenCV libraries in Windows
• Setting up the GLEW, GLM, SOIL, and OpenCV libraries in Mac OS X/Linux
• Creating your first vertex and fragment shader using GLSL
• Rendering 2D images with texture mapping
• Real-time video rendering with filters

Introduction

In this chapter, we will introduce OpenGL techniques to visualize another important class of datasets: those involving images or videos. Such datasets are commonly encountered in many fields, including medical imaging applications. To enable the rendering of images, we will discuss fundamental OpenGL concepts ...
