In anatomical illustrations deformation is often used to increase expressivity, to improve spatial comprehension and to enable an
unobstructed view onto otherwise occluded structures. Based on our analysis and classification of deformations frequently found
in anatomical textbooks we introduce a technique for interactively creating such deformations of volumetric data acquired with
medical scanners. Our approach exploits the 3D ChainMail algorithm in combination with a GPU-based ray-casting renderer
in order to perform deformations. Thus complex, interactive deformations become possible without a costly preprocessing or
the necessity to reduce the data set resolution. For cutting operations we provide a template-based interaction technique which
supports precise control of the cutting parameters. For commonly used deformation operations we provide adaptable interaction
templates, whereas arbitrary deformations can be specified by using a point-and-drag interface
