ABSTRACT:
A computer modeling and visualization system employs both 3D visual modeling and force feedback through a haptic device consistent with the visual display of the computer model. Force, or haptic, interaction is employed for exploring computer models. Point contact force equations were created for quickly computing forces directly from a model data which are provided to the haptic device, causing it to apply that force to an operator. The force equations employed are consistent with isosurface and volume rendering, providing a strong correspondence between visual and haptic rendering. The method not only offers the ability to see and feel the volumetric model but allows interactive modification and display of the model.
