The title of my doctorate is "Cloth Modelling and Visualisation". The research involves the design and evaluation of virtual clothing. We regard virtual clothing as computer models to simulate a photo-realistic appearance of real apparel. The aim is to develop technology to seamlessly and automatically implant images of virtual clothing into photographs of real environments.

For the simulation of cloth drape behaviour, so called mass-spring particle systems are harnessed. To mimic the drape behaviour of real fabric physical properties, such as resistance to stretching, shearing and bending, acquired from the Kawabata Evaluation System (KES) are mapped to our computer model. Simulations of light interactions with virtual fabrics are carried out using global illumination methods. A good approximation to the complex light reflectance (BRDF) and transmittance (BTDF) behaviour of real fabric's microstructure is important for realism. In order to measure the accuracy and quality of the simulation image metrics, some of which take the human visual system (HVS) into consideration, are investigated to quantify the difference between photographs of real garments and simulated garments blended into real scenes.
