CS 418: Laboratory 8

Modeling and Scientific Visualization

Introduction.

Scientific visualization is a term which refers to the process of converting data into pictures. This lab will demonstrate several of the techniques of visualization. The techniques will be used to view a simulated landscape, complete with rivers and clouds. The examples shown below are the result of calculating:


Procedure:

You will need to download the program

The program caluclates a 2D field of altitudes to make a landscape. It also calculates a 3D scalar field of densities to use as a cloud. These two fields are manipulated (e.g. to derive the slope of the surface), then visualized. New modules which are used include the:

You may want to look at the example programs in /usr/lpp/dx/samples/programs/ for further examples that use these modules.


Assignment:

Run the program a few times to see what it does. Try out various options on the control panel. Modify the program to add the following features:

Some results from 1996 .

You will need to demo all of the assigned functions in one modified net with the appropriate interactors to control the functions you have added. As usual, the style of the program will be graded, as will its function. The cloud animation may be in a separate program.

The Lab 8 grading guide will be filled out by a consultant during section to evaluate your work.
