An implicit-based haptic rendering technique

A a Novel Haptic Rendering Technique Using a Hybrid Surface Representation Addresses Conventional Limitations in Haptic Displays. a Haptic-rendering Technique Based on Hybrid Surface Representation 66

explore, paint, and manipulate virtual 3D models in a natural way using a haptic display device. A haptic rendering algorithm must generate a force field to simulate the presence of these virtual objects and their surface properties (such as friction and texture), or to guide the user along a specific trajectory. We can roughly classify haptic rendering algorithms according to the surface repre...

An Implicit-Based Haptic Rendering Technique

Constraint-Based 3-DOF Haptic Rendering of Arbitrary Point Cloud Data

We present a constraint-based haptic rendering algorithm for arbitrary point cloud data. With the recent proliferation of low-cost range sensors, 3D point cloud data is readily available at high update rates. Challenges in haptic rendering of this data arise due to noise and poorly defined surface composition. We propose that point cloud data can be rendered as an implicit surface, which can be...

Haptic Rendering for Internal Content of an Implicit Object

The haptic rendering algorithms for object with implicit surface representation are proposed. The basic rendering algorithm for a regular two-dimensional manifold is used to represent a solid volumetric object. For applications where information about the internal content of an object is concerned, the haptic rendering algorithm for internal content of an implicit object is developed. The propo...

A new Approach to Solve Constraint Forces of Virtual Fixtures in Haptic rendering

We present in this paper an iterative algorithm to solve constraint forces for haptic interactive simulation. The haptic forces are induced by interaction with guidance virtual fixtures having forbidden regions. In general, a haptic rendering based on an explicit formulation of the constraint forces (with virtual springs) can lead to severe numerical stability problems in case of hard constrain...
