It focuses on the mathematical and computational foundations of image generation and processing rather than purely aesthetic issues.
Among them are the SIGGRAPH and Eurographics conferences and the Association for Computing Machinery (ACM) Transactions on Graphics journal.
Because the appearance of an object depends largely on its exterior, boundary representations are most commonly used.
Recently, Eulerian surface descriptions (i.e., where spatial samples are fixed) such as level sets have been developed into a useful representation for deforming surfaces which undergo many topological changes (with fluids being the most notable example).
