Project 1

Objectives:

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

3D rotations,
user interaction,
hidden surfaces,
object selection.

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.

Due dates:

Project writeup and source: 02/09/99

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 writeup.

Description:

Write a program to implement a wireframe polygonal object viewer:

Use a windowing system (Xlib, glut, or gtk-gl) to open a graphics window.
Either through a GUI window or through keyboard/mouse facilities provided by glut, set up callbacks for toggling/setting various user-controlled options as well user-controlled object manipulation.
Whatever windows toolkit you use, you must provide a graphical mechanism for selecting/loading polygonal objects. If you're using:
- glut, use a pop-up menu,
- gtk-gl, use a file browser.
The program should read simple 3D objects (use polygonal object definitions found in .pol files).
Implement interactive control for the user providing object and camera transformations.
Implement hidden surface removal.
Implement object selection.
