Parametric tools for Majolica Domes Modelling

Bayesian Modelling of Prehistoric Corbelled Domes

The field of archaeology provides a rich source of complex, non-standard problems ideally suited to Bayesian inference. In this paper, we discuss the application of Bayesian methodology to prehistoric corbelled tomb data collected from a variety of sites around Europe. We show how the corresponding analyses may be carried out with the aid of reversible jump Markov chain Monte Carlo simulation t...

Tools for Semiphysical Modelling

SUMMARY Semiphysical modelling is often interpreted as an application of system identiication where physical insight into the application is used to come up with suitable non-linear transformations of the raw measurements so as to allow for a good model structure. This modelling procedure is lessàmbitious' than those used for traditional physical modelling in that no complete physical structure...

Parametric and Non-parametric System Modelling

The conditional parametric model is an extension of the well known linear regression model, obtained by replacing the parameters by smooth functions. Estimation in such models may be accomplished by fitting a, possibly larger, linear model locally to some explanatory variable(s). In this report the conditional parametric model is described together with a method of estimation. An S-PLUS / R imp...

Non-parametric Modelling

Sketch-based Interface for 3d Parametric Modelling

In this paper we present an experimental prototype called GEGROSS (GEsture & Geometric ReconstructiOn based Sketch System). This application allows using freehand sketches to create 3D parametric models onto a Tablet-PC. The modelling process consists of two stages. First, the user introduces the geometry of the 2D section using continuous sketches composed by line segments, circles and arcs, a...
