Computer Graphics is a vast discipline within computer science. It is also somewhat involved as it incorporates elements of data structures and algorithms as well as necessitating a good knowledge of mathematics and geometry. Although many students wish to jump straight to making animated movies, this course takes a different approach. In order to be a good computer graphics programmer, one must understand the underlying techniques, and not just call various functions and hope for the best. This course combines theory and practice; class time is split between covering the basics of various techniques along with some of the associated mathematics, and covering the more immediately practical use of OpenGL, the computer graphics API. Students will write several large programs to put theory into practice.

Assignment G6

• Marvin.bmp - output from the Roland PIX-30 3D scanner.
• project3 - sample G3 executable showing various order piecewise splines. Note: to run this after you have downloaded it, you have to make it executable by: chmod +x project3
• g3.in - sample input file for the above.
• windows.cpp - windows/viewports example.
• helloclass.cc - first practice program that draws a couple of polygons
• circle.cc - sample program showing how to draw circles with OpenGL.
• mouse.cc - program showing how to draw points and polylines with the mouse, version 1.
• mouse2.cc - program showing how to draw points and polylines with the mouse, version 2. The difference is that all of the points/vertices are stored, allowing the window to be redrawn whenever necessary.
• menu.cc - teeny program showing the use of a OpenGL pop-up menu.
• text.c - program showing some text output options.
• perspect1.cc - an example in the use of perspective. See the comments within the program that explain the use of glFrustum() and gluLookAt ().
• perspect2.cc - a more involved example in the use of perspective and other features, such as moving the camera position, wire-frame vs. solid objects, depth testing, and fog.
• myanimate.cc - a small example showing the basics of animation using a double-buffer.
• natelight.c - demo program showing the use of OpenGL lighting functions.
• shadingTex.csLab - executable (!) for Ubuntu in the csLab of the Dr Pepper bottles demo, showing the use of lighting and flat vs. smooth shading. Note: You may have to make this file executable after you copy it by: chmod +x shadingTex.csLab
  • dr_pepper_logo5.ppm - one of the texture images for a bottle label.
  • dp_frostyscreen.ppm - another texture image for a second bottle label.
• mytexture.cc - demo program showing the use of OpenGL texture functions.
  • CelebDM.ppm - texture image for above program.
  • glh.h - header file needed for above program.
  • glh.c - implementation code for above header file.
