(a): MRI of a human head -the 3D image has been classified
and a proper opacity function is automatically generated to distinguish
the brain cortex in this volume rendered image.
(b): the brain is segmented from the MRI, and a tetrahedral mesh is
generated of the brain cortex and interior (including brain ventricle).
(c): quadrilateral wireframe rendering showing the mesh interior of
a simplified version of the brain mesh.
Note the mesh adaptivity near the inner ventricles.
(d): surface quadrilateral mesh (16874 quads) of the simplified version
of the brain cortex being displayed.

the fast informative visulaization of volumetric imaging data
applying multi-transfer function. (e) shows outer surface of brain.
(f) shows inside of brain. (g) shows both surface and inside.
(h) shows a smooth surface from a surface triangulation by
implicit triangular surface patches
