Morph Volume Approach
The Morph Volume approach involves surrounding the mesh with one or more morph volumes, which are highly deformable six-sided prisms.
A number of methods exist to create the morph volumes, including single and matrix creation as well as the interactive on-screen method. Morph volumes support tangency between adjoining edges and allow for multiple control points along their edges. Handles placed at the corners and along the edges of the morph volumes allow for the morphing of the morph volumes which in turn morphs the mesh inside the morph volumes. The morph volume approach is quick and intuitive and is most useful for making large scale changes to complex meshes.
