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
