Metamorphosis

Animation:

Metamorphosis (shape transformation, morphing) between two functionally represented objects can be described by the interpolation between their defining functions. Such interpolation procedure defines a homotopy map in n+1-dimensional space. This makes possible metamorphosis between a blobby object and a constructive solid (frames shown above).

A picture shown above illustrates metamorphosis between four “key objects” normally modeled in different representational styles, but unified by F-rep here:

  • CSG solid
  • Swept spiral
  • Volumetric teapot
  • Blobby object
