Abstract:
1. A system for creating a hybrid representation of a three-dimensional object having one or more sharp edges, the system comprising: a user-controlled haptic interface device adapted to provide a user input to a computer and to transmit force to a user according to a user interface location in a virtual environment; and coded instructions that, when operating with said computer and said user input, are configured to: (a) generate a haptic representation of the three-dimensional object in said virtual environment, wherein said haptic representation is a hybrid representation comprising a volumetric portion and a geometric portion distinct from said volumetric portion, wherein said geometric portion defines at least one edge of said hybrid representation, and wherein the user can feel both the volumetric portion and the geometric portion; and (b) determine force transmitted to said user via said haptic interface device according to an interaction by said user with said three-dimensional object in said virtual environment.
