Tobias's CG Image Gallery Page

This page is intended as a showcase for some of the by-products of my work in visualization and computer graphics over the years.

Please feel free to check out some of my volume visualization images as well.

Do you need a high resolution texture map of the earth? This is a scaled down version of a 4320x2160x24 bit image. I created it from a geographical elevation map.
Here I used the above texture map for a visualization of a travelling salesman tour around 666 cities all over the world. The TSP data depicted here was provided by Prof. Martin Groetschel of the Technical University of Berlin (he is also vice president of ZIB, where I worked).
I used the Wavefront Advanced Visualizer package for rendering.
This image is a screen dump from a monitor that was complementing an Augmented Reality (AR) presentation at the ACM '97 conference: The unshapely cone guy on the platform represents a construction worker building a spaceframe structure. His position and head orientation are tracked. What you can't see here is the AR part: graphical, textual, and speech directions for the next construction step issued to the worker over a semi-transparent headworn display.
This image is a screen dump from another Augmented Reality application: The Mobile Journalist Terminal.
Labels and Multimedia information are overlaid onto the real world via a semi-transparent headworn display. The labels annotate real objects - in this case campus buildings - and can represent links to multimedia presentations (audio, image, video, text) - in this case about the riots on Columbia Campus back in '68. This image was produced from a test run of the program for which we used a hemisphere, texture mapped with an omnicam image, as the campus background. Blair MacIntyre wrote the code for the underlying AR environment and most of the demo application code.

More to come. Stay tuned...
