Abstract

We address the main issues in real-time visualization and interactive manipulation of highly textured surfaces. For applications such as cultural heritage, achieving this will give a vista to scientists, conservationists, historians, and visitors for looking at and studying important frescoed surfaces in virtual reality. Since photo-realism is of utmost importance, it became apparent that many problems related to geometric and radiometric distortions must be solved. As a case study, we present results of modelling and visualisation of 'Cycle of the Month', one of the major masterpieces of international Gothic art which is located in the Aquila tower in Buonconsiglio castle, Trento, Italy.
