MTK: A Direct 3D Manipulation Toolkit

: Advances in computer technology have made interactive 3D graphics systems a common tool for a variety of areas. Notwithstanding, most of such systems relies on popular 2D devices. To relieve system developers from the burden of implementing mapping techniques between 2D devices and 3D application data, some generic libraries have been proposed. However, those libraries still present limitations, either being complex to program or being limited in its interactive flexibility. As an alternative, we present a general purpose toolkit called MTK, which provides only basic interaction tasks. We also show that these tasks may be used to build sophisticated direct 3D manipulation techniques.
