Surface and Volume Morphing

November 17, 2005

Create blends of surfaces, such as car bodies or airplane fuselages, in order to give your design team new visual concepts or to explore the shape differences between two surfaces by using geometric morphometric analysis methods. Create realistic transitions between geometric models by smoothly translating vertex positions based upon motion capture data or manual specification.

Only when you need to align and register two three-dimensional volumes (such as MRI data) does one realize the complexity involved in doing this. Registering two volumes captured from the same specimen is one thing but consider registering volumetric images of two different human brains, a non-trivial task. Methods that morph and deform one volume to fit another are complex and require careful implementation to make sure the registration is done properly.

Consider having an atlas MRI dataset having annotations placed sporadically throughout the data. Volume morphing methods can be used to warp and deform a patient MRI dataset into the space of the atlas so that annotation can be applied quickly and automatically to the patient data.
