The purpose of the ACM Transactions on Graphics (TOG) is to further the development of computer graphics by encouraging high-quality research in the field and disseminating that research rapidly and widely. The term "computer graphics" is interpreted broadly to include topics in rendering, modeling, animation, and imaging. Example topics include geometric modeling, graphics hardware, rendering technologies, computer-aided design, color, perception, computational geometry, computational photography, human factors, image synthesis, interaction techniques (both 2D and 3D), lighting models, physical simulation, fabrication, and real-time techniques, among others.
