Geometric Transformations and Duality for Virtual Reality and Haptic Systems
نویسنده
چکیده
Virtual reality and haptic systems use geometric transformations with points represented in homogeneous coordinates extensively. In many cases interpolation and barycentric coordinates are used. However, developers do not fully use properties of projective representation to make algorithms stable, robust and faster. This paper describes geometric transformations and principle of duality which enables to solve some problems effectively.

متن کاملCombining physical constraints with geometric constraint-based modeling for virtual assembly
Virtual reality (VR) technology holds promise as a virtual prototyping (VP) toolfor mechanical assembly; however, several developmental challenges still need to beaddressed before virtual prototyping applications can successfully be integrated into theproduct realization process. This paper categorizes and elaborates these challenges and then describes how SHARP (System for Haptic A...
متن کاملStable haptic interaction with virtual environments
A haptic interface is a kinesthetic link between a human operator and a virtual environment. This paper addresses fundamental stability and performance issues associated with haptic interaction. It generalizes and extends the concept of a virtual coupling network, an artificial link between the haptic display and a virtual world, to include both the impedance and admittance models of haptic int...

متن کاملMulti-Finger Haptic Rendering of Deformable Objects
The present paper describes the integration of a multi-finger haptic device with deformable objects in an interactive environment. Repulsive forces are synthesized and rendered independently for each finger of a user wearing a Cybergrasp force-feedback glove. Deformation and contact models are based on mass-spring systems, and the issue of the user independence is dealt with through a geometric...
