Objectives:

To learn fundamental 3D graphics techniques (supported by OpenGL):

3D rotations,
user interaction,
hidden surfaces.

Motivation:

This project (1) examines the underlying calculations required to render simple 3D scenes, (2) reviews the basic data structures typically employed in graphical systems, and (3) covers interactive features of OpenGL and a GUI toolkit.

Due dates:

Project source: 02/24/00

Teams:

Although this is not advised until the final project, you may organize yourselves into pairs to complete this assignment.

If you form a pair, you must specify the ``division of labor'' (e.g., who did what) in your assignment TEAM file.

Description:

Write a program to implement a wireframe polygonal object viewer:

Use a high-level windowing toolkit (e.g., gtk with gtk-glarea) to open a graphics window (Xlib and glut ARE NOT high-level GUIs and should be avoided---if you choose either of these, you will have to implement your own buttons, file browsers, etc. otherwise points will be deducted).
Set up buttons and callbacks for toggling/setting various user-controlled options as well user-controlled object manipulation.
Implement user-adjustable face and normal display.
Whatever windows toolkit you use, you must provide a graphical mechanism for selecting/loading polygonal objects, i.e., a file browser to select object files from a directory.
The program should read simple 3D objects (use Alias|Wavefront polygonal object files--these will be provided).
Implement interactive control for the user providing object and camera transformations.
Implement hidden surface removal.

Notes, suggestions, warnings, and additional requirements:

Minimize the use of keyboard inputs.
Points will be deducted for: "klunky" interface, incorrect hidden face removal, lack of GUI buttons.

What to hand in:

``Professional-quality'' brief writeup (one writeup per team), placed in a TEAM plain text file including:

In a USAGE file, inlclude:

Program features
User guide

Electronic submission of source code: provide a self-contained, gzipped .tar of your project 1 directory, complete with a Makefile and README specifying compilation requirements. Your code MUST compile and run on an SGI O2.

Demonstartion of program on an SGI O2 workstation will be required.
