We present an approach utilising hybrid models, combining together both polygonal and Function Representation models. We perform model evaluation and rendering entirely on the GPU using NVidia CUDA SDK. Our approach allows us to produce animations involving dramatic changes of the shape (e.g. metamorphosis, mimicked viscoelastic behaviour, character modifications etc) and interactively create complex shapes with changing topology in short times.
