Recent years have witnessed significant advances in 3D brush modeling and simulation in digital paint tools. Compared with traditional 2D brushes, a 3D brush can be both more intuitive and more expressive by offering an experience closer to wielding a real, physical brush. To support popular media types such as oil and pastel, most previous 3D brush models(More)
Project Gustav is a digital painting system that enables artists to become immersed in the digital painting experience. It achieves interactivity and realism by leveraging the GPU to implement our novel art media modeling and brush simulation algorithms. Compared with current digital painting packages, there are two main advances over state-of-the-art. The(More)
This paper describes the implementation of an object-oriented programming system in TEX. The system separates formatting procedures from the document markup. It offers design programmers the benefits of object-oriented programming techniques. The inspiration for these macros comes from extensive book-production experience with W&X. This paper is a companion(More)
