3D Volume Metamorphosis Algorithms
In 3D morphing, creating the morphs is independent of the viewing and lighting
parameters. In 2D morphing, a new morph must be recomputed every time we
wish to alter our viewpoint or the illumination of the 3D model.
2D techniques, lacking information on the model's spatial configuration,
are unable to correctly handle changes in illumination and visibility.
Methods for 3-D Morphing
According to the use of control datasets, approaches to volume morphing
can be classified into three categories, namely:
Field ( feature-based) Morphing
3D Feature-based Morphing
Regular grids provide a cumbersome interface in 2D; in 3D they would likely
As in the 2D morphing system, the animator identifies two corresponding
features in source volume and destination volume, by defining a pair
Transformation between 2 elements
Some cool demos are created by studens of Stanford University. See
