An Interactive System for Modeling, Animating and Rendering of Functionally Defined Objects

An Interactive System for Modeling, Animating and Rendering of Functionally Defined Objects This paper describes interactive shape modeling of geometric objects defined by perturbation functions. 3D objects based on the perturbation functions have an advantage of spline representation of surfaces, that is, a high degree of smoothness, and an advantage of arbitrary form for a small number of perturbation functions. Interactive modification of the function-based model with fast visualization allows us to provide both the interactivity and any required level of detail leading to a photo-realistic appearance of the resulting shapes. An interactive system modeling is presented
