Geometric Modeling, Spring 2001
Homework 4 (Due: April 19, 2001)

In this homework, we will begin to use the Java 3D API towards our goal of constructing a modeler. The 3D API is a very powerful system, but we will begin by just learning about how to use the system to display, with basic GUI to change views.
The first step is to understand a certain dataset called Digital Elevation Model (DEM) from US Geological Survey. We have downloaded the DEM 7.5 Minute data for Jersey City. Your goal is to write a Java program to read this data and to display them using Java 3D.
You will need to know about SDTS (Spatial Data Transfer Standard). The file sdts_tutorial.txt (use sdts_tutor.txt if you want shorter lines) is a quick introduction. For more information go to gisdatadepot.com.

You can go to the source USGS Geographic Data Download to get similar data.
