T-61.271 Visualization project description
39. Combining color and texturesi

Autumn 2003

Read the project description carefully. Questions and comments can be sent to

General information

The purpose of the project work is to get hands on experience and deeper understanding on one specific area of the course. At the same time you will be forced to think on some of the more general issues that are confronted every time a visualization method is developed or used.

To complete the project you will probably need information that has not been discussed on the lectures or in the exercises. Most of the time relevant information can be easily found on the web, course books or in some cases references to articles will be given. If you have problems finding information on the subject please contact the lecturer or the assistant for hints and guidance.

The project work will be valid for one year after the original deadline.

General requirements

specific requirements

Healey and Enns have developed a method to code data values in a combination of textures and colors. The goal of this project is to create a tool to visualize large data sets using the ideas presented in their paper

Healey Christopehr, Enns James, 1999, Large Datasets at a Glance: Combining Textures and Colors in Scientific Visualization. IEEE Transactions on Visualization and Computer Graphics, Vol. 5, No. 2, p 145-167.

The tool should have the following features

  1. It should read the data from a file.

  2. It should allow the combination of features to visualization elements to be arbitrary.

In the report you should illustrate the use of the method on one suitable data set of your choice. You should also discuss the strengths and weaknesses of the method.
