Interactive Computer Graphics with WebGL, Global Edition
Autor Dave Shreiner, Edward Angelen Limba Engleză Paperback – 12 oct 2014
Computer animation and graphics are now prevalent in everyday life from the computer screen, to the movie screen, to the smart phone screen. The growing excitement about WebGL applications and their ability to integrate HTML5, inspired the authors to exclusively use WebGL in the Seventh Edition of Interactive Computer Graphics with WebGL. Thisis the only introduction to computer graphics text for undergraduates that fully integrates WebGL and emphasizes application-based programming. The top-down, programming-oriented approach allows for coverage of engaging 3D material early in the course so students immediately begin to create their own 3D graphics.
Teaching and Learning Experience
This program will provide a better teaching and learning experience-for you and your students. It will help:
- Engage Students Immediately with 3D Material: A top-down, programming-oriented approach allows for coverage of engaging 3D material early in the course so students immediately begin to create their own graphics.
- Introduce Computer Graphics Programming with WebGL and JavaScript: WebGL is not only fully shader-based-each application must provide at least a vertex shader and a fragment shader-but also a version that works within the latest web browsers.
