%K computer model, pinscreen simulation.
%X This paper presentes a computer model that simulates the traditional physical pinscreen image synthesis process. The basic goal is to enhance the artists ability to express themselves. Prinscreen is a very particular and difficult device that enables a chiaroscuro approach to image synthesis. In this paper we describe with some detail the traditional pinscreen technique, the way is operated, results and relates difficulties. A first basic computer model to simulate the pinscreen is presented. New important extensions to the basic model are also proposed. Advantages and possibilities of the method when compared with the traditional method and the problems that arise from this technique will also be explained.
