Electronic CG Textbook based on Java and HTML Jiaoying Shi State Key Lab of CAD&CG, Zhejiang University, Hanzhou, P.R.China

Computer Graphics Education b b Traditional CG education blackboards, slides, and even videos  computer supported education b Limitation of existing methods (1) suffers from the lack of interaction opportunities (1) suffers from the lack of interaction opportunities (2) limiting any kind of explorative learning to a minimum (2) limiting any kind of explorative learning to a minimum (3) Do not support remote education (3) Do not support remote education

Our Aim and Method b b Web-Based Education: Users can access through HTML Java b b High-level Interaction: (1) Select the content to be learned (2) Interact with CG algorithms written in Java b b Multimedia presentation: Figure/Graphics/image/animation/video

Available Techniques b b World Wide Web/HTML: framework to generate common interfaces for the integration of all elements of CG courses( lectures, examples, exercises, and consolidating literature references) b b Java: (1) supports platform independence (2) allow students to collaborate with each other and their tutors and to complete and explore the exercises at home b b High-performance 3D graphics on PCs most of the students have their own system and, because it has the potential to do 3D graphics

Aim for Content Organization b b teaching the fundamentals of CG and their programming, without restricting us to the use of existing graphics systems, b b giving an insight into the research methods and experimentation that actually occurs in the development of new graphics techniques. b b providing a flexible i.e. easily extensible and modifiable teaching environment, thus not being exclusively tailored to the area of computer graphics education but adaptable to other areas ( geometric modeling, ViSC).

CG Course Content b b Basic CG concepts and principles b b Computer graphics hardware b b raster algorithms with aliasing and anti-aliasing b b 3D-transformations b b visibility-determination algorithms, b b modeling techniques b b simple animation b b texture mapping, global illumination techniques (ray-tracing, radiosity) b b volume visualization.

Experimental Results b b Two Versions for such CG course Chinese English b b Implement most part of the topics listed above b b CD-ROM publishing for the CG course b b Put it on the China Graphics Engineering Web site ( (available after Sept. 1, 2000)

Conclusion and future Work b b Introduce our work for Web-based CG education b b Java and HTML based electronic textbook will be widely used. b b A lot of We-based courses are being developed in China supported by the Dept.of Education of our government b b We will develop similar course on: Visualization Geometric Modelling Animation Virtual Reality
