Presentation Transcript

  1. CS 470 Computer Graphic Getting Started with OpenGL

  2. Three Parts • OpenGL • glu • glut

  3. opengl • 200 functions • Primitives • Geometric • Discrete (bitmaps) • Attribute functions • Viewing functions

  4. glu • GLU is the OpenGL Utility Library. This is a set of functions to create texture bitmaps from a base image, map coordinates between screen and object space, …

  5. glut • GLUT is the OpenGL Utility Toolkit, a window system independent toolkit for writing OpenGL programs • Generic windows interface • Provides user interaction functionsM

  6. Others • GLX 1.3 is used on Unix OpenGL implementation to manage interaction with the X Window System and to encode OpenGL onto the X protocol stream for remote rendering. • Mesa is a 3-D graphics library with an API which is very similar to that of OpenGL .

  7. You will need… • Opengl • should be there • glu • should be there • glut • Mac – should be there • Linux – should be there if you installed opengl • Windows – may need to download and install

  8. glut • For windows download glut from http://www.xmission.com/~nate/glut.html glut32.dll Windows XP | Server 2003: C:\WINDOWS\system\ Windows 2000: C:\WINNT\system\ glut32.lib C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Lib glut32.h C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\gl

  9. Building programs in opengl

  10. Mac

  11. Linux gcc simplegl2.c -o simplegl2 -lGL -lGLU -lglut \ -L/usr/local/packages/Mesa-6.0.1/lib/ -lm -lX11 \ -L/usr/X11R6/ \ -I/usr/local/packages/Mesa-6.0.1/include/GL/

  12. Windows
