Abstract. Properly designed and structured ground-based geodetic networks materialize the reference systems to support sub-mm global change meas-urements over space, time and evolving technolo-gies....
Highly stylised animation (2008)
Di Fiore, F, Van Reeth, F, Patterson, J, Willis, P
In this paper we argue for our NPAR system as an effective 2D alternative to most of NPR research which is focused on frame coherent stylised rendering of 3D models. Our approach gives a highly...

A survey of partial differential equations in geometric design (2008)
Castro, G. G., Ugail, H., Willis, P., Palmer, I.
Computer-aided geometric design is an area where the improvement of surface generation techniques is an everlasting demand, since faster and more accurate geometric models are required. Traditional...
First Assessment Of Dynamic (2007)
Determination On Yunck, T. P. Yunck, W. I. Bertiger, S. C. Wu, Y. Bar-sever, E. J. Christensen, ...
. The reduced dynamic tracking technique has been applied for the first time as part of the GPS experiment on This technique employs local geometric position corrections to reduce orbit errors by the...

Projective alpha colour (2006)
Alpha colours were introduced for image compositing, using a pixel coverage model. Algebraically they resemble homogeneous coordinates, widely used in projective geometry calculations. We show why...

Virtual physics for virtual reality (2004)
We consider the problem of giving virtual reality objects physical behaviour We wish to do this in a way which allows users to construct new objects from simpler ones and have the correct composite...
Image interpolation by pixel-level data-dependent triangulation (2004)
We present a novel image interpolation algorithm. The algorithm can be used in arbitrary resolution enhancement, arbitrary rotation and other applications of still images in continuous space....
Willis, P., Dortmans, P., Curtis, N., Tri, N.
Concept proliferation is common to most western military organisations in the 21st Century. The aim, purpose and relationships of these concepts can be confusing. Army’s Concept Framework is...
A layered dynamic emotion representation for the creation of complex facial expressions (2003)
Tanguy, E., Willis, P., Bryson, J.
This paper describes the Dynamic Emotional Representation (DER): a series of modules for representing and combining the many different types and time-courses of internal state which underly complex,...
Demosaicing of colour images using pixel level data-dependent triangulation (2003)
Single-chip digital cameras use an array of broad-spectrum Charge-Coupled Devices (CCD) overlayed with a colour filter array. The filter layer consists of transparent patches of red, green and blue,...
