The Function Representation (or FRep) defines a geometric object by a single real continuous function of point coordinates as
It combines many different models like
Main features of FRep:
The main goal of this project is to develop a rich system of geometric operations and relations. Our approach is based on the R-functions - continuous definitions of set-theoretic operations.
FRep can also be used to model point-wise object's properties such as material, density, color. This is supported by the constructive hypervolume model.
We apply theoretic results in different areas:
Frequently asked question: Why not just "implicit" surfaces?
This FRep Home Page represents the results of joint work by an international group of researchers (see the authors of publications).
