DESCRIPTION

In the past, serious computer graphics programmers generally had to use "industrial strength" workstation hardware and software. Now, advanced graphics capabilities have become available in the PC arena. Whether you're a programmer, 3D enthusiast, C++ coder, games developer or animation specialist, POWER-3D will help you with fast, practical 3D implementations in the Windows environments.

What's inside:

• Coverage of three-dimensional mathematics with code examples in C++
• Full source code and documentation of many C++ objects for 3D graphics:
  Intersection calculations
  N-dimensional splines
  Vertex object that encapsulates the world of 3D
  Viewing volume clipping
  Texturing
  Lighting
  Tessellating
  Implicit surfaces
  Constructive Boolean geometry
  and much much more!
  
• COpenGLView object that lets you use OpenGL right now!
• A CD with a treasure trove of 3D graphics source code and program demos from all over the world.

WHAT THE EXPERTS SAY ABOUT THIS BOOK...

"The best book on 3D graphics programming on the PC and Windows I've ever read."
-Brian Hook, author of Building a 3D Game Engine in C++

"... the writing style makes learning the subject matter easy ... and his coverage of graphics techniques for Windows 95 and NT will assist every reader."
-Peter Kovach, President, I.C.A.T.

"... the book will interest any programmer looking to get into 3D. I liked it very much and will recommend it to my colleagues."
-Frank Bruno, Number Nine Visual Technology
