Chapter 3. Interactive 3D Data Visualization

In this chapter, we will cover the following topics:

Setting up a virtual camera for 3D rendering
Creating a 3D plot with perspective rendering
Creating an interactive environment with GLFW
Rendering a volumetric dataset – MCML simulation

Introduction

OpenGL is a very attractive platform for creating dynamic, highly interactive tools for visualizing data in 3D. In this chapter, we will build upon the fundamental concepts discussed in the previous chapter and extend our demos to incorporate more sophisticated OpenGL features for 3D rendering. To enable 3D visualization, we will first introduce the basic steps of setting up a virtual camera in OpenGL. In addition, to create more interactive demos, we will introduce the use of GLFW callback functions for handling user inputs. Using these concepts, we will illustrate how to create an interactive 3D plot with perspective rendering using OpenGL. Finally, we will demonstrate how to render...

Raymond Chun Hing Lo

Raymond Chun Hing Lo

Raymond C. H. Lo is currently the CTO and co-founder of Meta, a company in Silicon Valley that is creating the world's first augmented reality eyeglasses with 3D gesture input and 3D stereoscopic display. This next-generation wearable computing technology, which is the result of his PhD research, has been featured extensively in news media, including CNN, MIT News, CNET, and Forbes magazine. During his PhD, Raymond worked with Professor Steve Mann, who is widely recognized as the father of wearable computing. Together, they published and presented papers at leading conferences, including the SIGGRAPH and IEEE conferences, on real-time high-dynamic-range (HDR) imaging, augmented reality, and digital eyeglasses, which involve high-performance computation using CUDA and visualization using OpenGL.

Muhammad Mobeen Movania received his PhD degree in Advanced Computer Graphics and Visualization from Nanyang Technological University (NTU), Singapore. He completed his Bachelor of Science Honors (BCS(H)) in Computer Sciences from Iqra University, Karachi. Before joining NTU, he was a junior graphics programmer at Data Communication and Control (DCC) Pvt. Ltd. Karachi, Pakistan. He was working on DirectX and OpenGL API for producing real-time interactive tactical simulators and dynamic integrated training simulators. His research interests include volumetric rendering, GPU technologies, real-time shadows, digital geometry processing, and hierarchical geometric data structures. He is also the author of an OpenCloth project which implements various cloth simulation algorithms in OpenGL. His blog lists a lot of useful graphics tips and tricks. When not involved with computer graphics, he composes music and is an avid squash player. He is currently working at a research institute in Singapore.
