Introduction
The main goal of this project is the interactive
visualization and manipulation of the Visible Human data set in a multiprojection immersive environment.
Introduction
VolumePro (Volumetric hardware graphic board) Stereo Glasses (Stereoscopic view) Data Glove (Movements of the virtual head) CAVERNA Digital (LSI - USP)
System Modeling
This project was implemented in C and C++ language, using VLI VolumePro and OpenGL GLUT.

Gestures
For movements we used the following gestures:• Gesture 0: Rotate in y axis with an maximum 180° angle;
• Gesture 1: Apply the cut plane;
• Gesture 3: Rotate in x axis with an maximum 180° angle;
• Gesture 7: Rotate the cut plane in x and y axis with an maximum 180° angle;
• Gesture 8: Apply transparency;
• Gesture 9: Activate stereoscopic visualization;
• Gesture 14: Rotate the cut plane in z-axis with a maximum 180° angle.
Manipulation
Future Works
To implement another segmentation technique, to separate some parts of the human body, to generate a volume only from a region of interest.
The user would be able to interact traveling into the human body
