#### Convexity-preserving B-spline modification

(Lincoln University. Centre for Computing and Biometrics, 1997-10)

This report discusses the problem of modifying the shape of a cubic B-spline curve while retaining its convexity. This is achieved by moving control points in such a way as to maintain the appropriate shape of the corresponding ...

#### Discrete lines and ant algorithms

(Lincoln University. Applied Computing, Mathematics and Statistics Group, 2001-03)

This is a report on work in progress. The focus is on the design of an
algorithm used to construct discrete lines. It is intended that this is the
first step in applying models of complex adaptive systems to more complex ...

#### Interactive shape preserving interpolation by curvature continuous rational cubic splines

(Lincoln University. Applied Computing, Mathematics and Statistics Group, 1999-01)

A scheme is described for interactively modifying the shape of
convexity preserving planar interpolating curves. An initial curve is
obtained by patching together rational cubic and straight line segments.
This scheme has, ...

#### Constrained visualization using the Shepard Interpolation Family

(Lincoln University. Applied Computing, Mathematics and Statistics Group, 2003-12)

This paper discusses the problem of visualizing data where there are underlying constraints that must be preserved. For example, we may know that the data is inherently positive. We show how the Modified Quadratic Shepard ...

#### Three dimensional world construction with LEGO blocks

(Lincoln University. Applied Computing, Mathematics and Statistics Group, 2004-04)

In this project a three dimensional virtual world is constructed with the use of a LEGO camera and a set of LEGO blocks. The goal is to design a construction method that is simple enough for middle school-aged children to ...

#### Cellular lines: an introduction

(Lincoln University. Applied Computing, Mathematics and Statistics Group, 2003)

This paper provides a definition of a cellular line in a cellular array. It also presents a way of determining whether or not a cell set is a cellular line. Brief statements about existence, uniqueness, and properties of ...
