Download or read book Visualization of Basic Transformations in Computer Graphics written by Xiao Feng Jin and published by . This book was released on 2003 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transformations play a basic and key role in OpenGL and computer graphics. Basic transformations, which are represented by matrix multiplication, include modelling, viewing, and projection transformations. They involve rotations, translations, scalings, reflecting, orthographic and perspective projection. This report describes the design and implementation of visualization tool for basic transformations. First all, we describe basic transformations in OpenGL, such as viewing, modelling, projection, and viewport transformations. And we describe some ways to implement these transformations. Secondly, we give the detailed description of design and implementation based on the above specification. In the design stage, we consider the following transformations: viewing, modelling, and viewport transformations are called "model view"' and the "projection" transformation. In implementation stage, we implement coding depending on the above design, namely, "model view transformation" visualization and "projection transformation" visualization. Finally, we include user's guide, and some open problem.
