Organic Modelling with Generalised Cylinders (12/20pt project) JM1

Generalised cylinders are a geometric modelling method, originally developed for use in computer vision. For this project we wish to apply them to the modelling of organic structures for computer graphics. The basic principle for creating a generalised cylinder is to define a series of cross-sectional profiles, possibly of varying shape and size, and distribute them over some continuous curve, known as the carrier curve. The cross-sections are connected to form a continuous surface. Sounds easy, but there are a number of important issues that need to be addressed to ensure that the geometry defined by the cylinder is legal (i.e. can be rendered). Constructing compound surfaces is very useful for modelling organic structures such as branches, leaves, tentacles, veins, shells, etc., as this image (below) illustrates. The image is procedurally generated using generalised cylinders.

The challenge for this project will be to create a software system to assist in the automated construction of such models using generalised cylinders. The system will also have to deal with managing geometric complexity and geometric output in a variety of formats (e.g. real-time, offline rendering). The software for the project should be written in C++ and OpenGL. You should have successfully completed CSE3313 Computer Graphics (or equivalent) in order to work on this project.

Interactive Adaptive Learning Systems (12/20pt project) JM2

This project will investigate the use of adaptive learning systems for a real-time interactive application. Collections of virtual creatures are required to develop a symbiotic relationship with a human audience – responding to movement and gesture. Students should be prepared to investigate a number of adaptive learning techniques including classifier systems and evolutionary ANN (Artificial Neural Network) approaches, with the goal of creating a novel system that evolves and adapts to its real and virtual environments. The key emphasis for this system must be flexibility and real-time behaviour as the dynamic environment is actually changing in real-time.

The Illusion of Beauty (20pt project) JM3

What is beauty and what makes a thing beautiful? Is beauty a property of things and can it be measured? This was famously answered by the mathematician Birkhoff who in 1933 proposed an 'aesthetic measure', equal to the ratio of order to complexity. Birkhoff was able to measure the aesthetics of simple shapes and vases. However, the measure was not successful in general. Many principles of what makes a good picture are well known, i.e. in composition we talk of balance, entrance and exit, symmetry, etc. as properties of what is considered a good composition. For this project the challenge is to try and encode or infer rules about visual composition to see if we can devise a better aesthetic measure of an image. This could have all sorts of applications, for example, automated selection of camera positions in 3D virtual environments, use as "fitness functions" to be used in evolutionary programs and so on — read this paper as a good starting point. Would we think a computer that can make beautiful images as being creative?
