Here is a summary of the components needed to run the entire simulator
PHANToM: PHANToM is a force feedback device that allows the user to feel the surface in Microscape and to manipulate the image/surface.
Microscape : Microscape is a graphics program that visually displays the scanned image. From Microscape the image can be looked at and felt (using the PHANToM device) from different angles. Both the commands to alter or retrieve current scanned data and the returned requested values are sent through VRPN encoded messages from Microscape and to Microscape. For proper display of the surface in Microscape a setup file should be included.
VRPN (Virtual-Reality Peripheral Network) : The Virtual-Reality Peripheral Network (VRPN) is a set of classes within a library and a set of servers that are designed to implement a network-transparent interface between application programs and the set of physical devices used in a virtual-reality (VR) system. The idea is to have a PC or other host at each VR station that controls the peripherals (tracker, button device, sound, etc). VRPN provides connections between the application and all of the devices using the appropriate class-of-service for each type of device sharing this link. The application remains unaware of the network topology.
