Abstract
In this paper we consider the problem of fitting a fixed, free form surface to coordinate
data. We describe an algorithm using a separation of variables approach that
allows probe radius compensation to be implemented in an accurate and simple
way. We also show how to generate test data with which to validate surface,fitting
algorithms. By comparison with the surface3itting problem, the data generation is
extremely straightforward and requires o n l r a capability to generate points lying
exactly on a surface along with their corresponding normal vectors. The data generation
also caters for probe radius compensation in a simple way. The main advantage
of the data"generation scheme is that it allows the behaviour of approximate
solution algorithms to be assessed without the need to implement a comprehensive
algorith~
