FreeForm Deformation for Implicit Surfaces: A SketchBased Method to Control Deformation in a Skeletal Implicit Surface Modeler,Used
Delivery time: 8-12 business days (International)
Implicit surfaces offer many advantages for sketch based modeling systems, such as blending, CSG, and a procedural object hierarchy. Freeform deformation (FFD) is also extremely useful in this context, however existing FFD approaches do not support implicit surface representations, and FFD lattice manipulation is timeconsuming compared to sketch based techniques. In this thesis, an FFD technique suitable for implicit surface representations is described. To enhance realtime feedback, the problem is split into an approximate formulation used during interactive deformation, and a more robust variational technique which preserves desirable scalar field properties. As an interface to manipulate the deformation, a sketchbased volumetric peeling interface is introduced. The user's task is to draw a curve on the surface, and pull or push the surface to the desirable position via the curve. Subsequently, the deformation is automatically defined. This technique has been implemented in a prototype implicit FFD system called Taco. Results created in Taco show that a desirable deformation can be easily achieved while preserving implicit properties.

increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
