چکیده

The modeling of large biomolecular assemblies frequently requires a combination of multi-resolution data from a variety of biophysical sources. Several algorithmic solutions to this docking problem have been proposed which are usually based on the spatial cross correlation. In [1] it was shown that Laplace-filtering techniques can improve the docking performance of these algorithms. This note presents the implementation and first results of the Laplace-filter enhanced fitting into the interactive SenSitus program, which supports the docking by virtual reality (VR) techniques (3D-stereoscopic view and haptic rendering). This implementation has to consider the special needs of the interactive rendering strategy. We employ reduced models using vector quantization to achieve the required force update rate.

Evaluation of Velocity Estimation Methods Based on their Effect on Haptic Device Performance

This paper comparatively evaluates the effect of real-time velocity estimation methods on passivity and fidelity of virtual walls implemented using haptic interfaces. Impedance width, or Z-width is a fundamental measure of performance in haptic devices. Limited accuracy of velocity estimates from position encoder data is an impediment in improving the Zwidth in haptic interfaces. We study the e...

Combined Hapto-visual and Auditory Rendering of Cultural Heritage Objects

In this work, we develop a multi-modal rendering framework comprising of hapto-visual and auditory data. The prime focus is to haptically render point cloud data representing virtual 3-D models of cultural significance and also to handle their affine transformations. Cultural heritage objects could potentially be very large and one may be required to render the object at various scales of detai...
