Synopsis:
Volume graphics is concerned with graphics scenes, where models are defined using volume representations instead of, or in addition to, traditional surface representations. Volume visualization is also concerned with volume data representations that are used to store measured physical attributes of real-world objects and phenomena, or to represent computer-generated models and their attributes in volumetric forms. Whilst the two subjects have rather different objectives, they share the same underlying mathematical concepts, and a large collection of algorithms and techniques. Meanwhile, they also face a common challenge of displaying true-3D graphical models on 2D computer screens and paper media.
Professor Min Chen is the main organizer of the first International Workshop on Volume Graphics at Swansea in 1999, and the author of the entry on “Volume Graphics and Volume Visualization” in Wiley Encyclopedia of Computer Science and Engineering, and that on “Volume Graphics” in Encyclopedia of Microcomputers. In this seminar, he will introduce the theoretical foundations and applications of these two closely-related subjects, and will cover the main techniques for modelling, manipulating and rendering volumetric representations with the following syllabus:
- Introduction: Objectives, historical development, and applications (e.g., medical imaging and scientific computing).
- Volumetric Data Types: Concept of scalar fields, regular and irregular data types, multi-fields, and functional volumetric models.
- Volume and Surface: Concepts of iso-surfaces. Surface extraction. Ambiguity problems and solutions. Acceleration techniques. Voxelization and distance fields.
- Direct Volume Rendering: Volume rendering integral. Transfer functions. Ray-casting algorithms. Forward projection algorithms. Acceleration techniques.
- Advanced Topics: Constructive volume geometry (CVG). Discrete ray tracing. Volume deformation and animation.
