====== Augmented Sculpture Project ======

In this project we investigate an approach to computer-based sculpting concerned with the creation and modification of digital models based on physical abstract sculptures. We present some original methods and tools based on the [[frep:main|Function Representation]] of geometric models. We use a specialised computer language [[:main|HyperFun]], which facilitates the modelling of complex objects. As well as presenting computer-generated animated models of pre-existing sculptures, we also show how interesting novel shapes can be generated using the HyperFun system. Here, we outline an early stage of the project development concerned with creating a sculpture-based augmented reality which allows for the interactive participation of the observer.
