CMP 160 -- Programming Assignment 5

Learn viewing transformations and texture mapping. Note that the assignment below is built upon your earlier programs.

First requirement is to allow user to toggle between orthographic and perspective projections. Select a reasonable combination of view volume and projection plane distance to camera so that switching between the two modes is not too drastic.
Second requirement is to allow the user to change his/her viewpoint within the world. Try to minimize the use of xform sliders as much as you can.
Final requirement is to apply some texture image onto the object. Experiment with different texture images and different mapping strategies. "xv" is a nice program if you need to do simple image editing or converting among different popular image formats.
As in earlier programs, allow the objects and lights to be manipulated.

Use the data files in the class directory: /afs/cats.ucsc.edu/class/cmps160.f99/data. If you are using other data sets, be sure to include them with your submission.
Rotating viewpoints is illustrated by the following java3d online example . Hopefully, this will be viewable on the nt's and suns... If not yet, you can also try "appletviewer". At least the java3d source is viewable and maybe that might help.
Another java3d example, though a bit buggy, illustrates the viewing system .
There's a number of examples in /afs/cats.ucsc.edu/class/cmps160.f99/openglbk that illustrate how to do texture mapping. Obviously, image files can be used in place of generating own textures.
Also take a look at some great examples in /afs/cats.ucsc.edu/users/i/yiff/src/homework/cmps160/tutor. Specifically, look at "texture" and "projection" to get a better understanding of texture mapping and viewpoint manipulation in OpenGL.
A simple texture mapping tutorial at the Univ of Alberta includes how to read in a raw rgb file.
Some useful OpenGL functions (see the man pages): glMatrixMode, glFrustum, gluLookAt, gluPerspective.
Submission must be done using the submit or xsubmit utility from CATS. Run "quickhelp submit" on a CATS machine to find out more info. Create and submit a subdirectory called "prog5". It should contain all the files you have in make your program compile/run. This includes folks using Windows/NT/MAC environments.
