Project 2

Objectives:

To learn fractal terrain modeling, direct illumination and shading models.

Motivation:

This project examines (1) stochastic procedural object modeling (surface subdivision based and fractional Brownian motion), (2) simple direct illumination and shading models.

Due dates:

Project writeup and source: 03/09/99

Description:

Write a program to implement a ``fractal mountain'' modeler:

• Provide a Graphical User Interface (GUI) to a simple object modeler, within which a user can read in polygonal objects (e.g., .pol files).
• Manually create a triangle or quadrilateral which will serve as the fractal mountain base.
• Recursively subdivide the polygon to a user-specified level, or a level dependent on distance to the viewpoint.
• Using your own ligthing (illumination) calculation, use OpenGL to shade objects in the scene. Provide both facetted (flat) and smooth shading of explicitly defined polygonal objects, but use only flat shading to color the mountain.

Notes, suggestions, and additional requirements:

• Use the winged-edge data structure to facilitate polygonal subdivision (the winged-edge data structure provides pointers to faces shared by the edge).
