Done (in C) : 3D Reconstruction Of Human Head from VH MRI data set
|
The original data set consists of 28 slices (spaced 4 mm apart)
-
Connectivity algorithm - the tissue of interest is isolated from surrounding data
-
Marching cube algorithm - identifies polygons that make up the surface
-
Visualization step - construction of 3D transformation matrix for any rotations
-
Z-buffer algorithm - visible surface determination
-
Gourad shading algorithm - intensity values for vertices
|
|
In the 3D virtual tour through reconstructed tissue, we have to consider transparency and opacity factors, light sources, shading, rotation and enlargement, the ability to "fly in" the tissue sample from arbitrary angles; interaction
