Volumetric Data

April 6, 2004

Visible Human

• Creation of complete, anatomically detailed, three-dimensional representations of the normal male and female human bodies.

• CT, MR and cryosection images were acquired

• Male was sectioned at one millimeter intervals

• Female at one-third of a millimeter intervals

What can you do with all that data????

• Browser

• Knee with animated alpha channels

Given a series of images: how do you create a surface model?

• Threshold at some density to produce binary image.

• Select area of interest. Find outer edge of that area.

• Use marching cubes algorithm to produce surface volume.

Homework

• Final Project Proposal due Thursday– Project Guidelines

• OpenGL program – must be interactive, such as a game or a visualization

• Maya Project – model, animate and render a real-world object, include its realistic movements.

• Final Project Phase 1 - some graphic output due 4/15.
