Project 3 -- Mountain Terrain Generator

Overview

For this assignment, you will implement a program to generate fractal terrain modeling.

Due Date

Project writeup and source: 4/27/2000

Description

This project examines stochastic procedural object modeling, that is, surface subdivision based on fractional Brownian motion.

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

• Manually create an object of consisting of triangles or some other type of polygons which will serve as the fractal mountain base.
• Recursively subdivide the polygons to an appropriate level.
• Use OpenGL, your ray tracer, or any other renderer to shade objects in the scene. You may provide faceted (flat) or smooth shading of explicitly defined polygonal objects.

Suggestions

• You need only write the code for the polygon subdivision. Use whatever renderer you like to get the best final effect.
• Your code need not be robust enough to handle a variety of cases -- you can hard-code the scenes if you like.
• You may want to place a simple body of water or ice around your mountain range.

Submission Requirements

• ``Professional-quality'' brief writeup, including:
  1. Cover page containing: Course Id--Section No.

  2. Assignment description
  3. Program features
  4. Any interesting problems you ran into and how you resolved them

• One or two nice mountain images. Provide an image of the range that shows the polygons you generated (flat-shaded) for each mountain range. Try to produce an additional image with textures to produce a more realistic terrain effect.

• Electronic submission of source code: provide a self-contained, compressed .tar file (preferably gzipped), complete with a Makefile and README specifying compilation requirements.

• In-class demonstration of your program will be required.
