Supporting Interactive Haptic Shaping of 3D Geologic Surfaces with Deformation Property Painting

چکیده
Meshes made from 3D points are used to represent many important geoscience concepts such as the surface of the Earth (topography), rock strata (horizons) and faults. When creating complex computer models, a geoscientist may need to directly affect the shape of such a surface to bring in in line with other data. We present a method that allows a geoscientist to precisely interact with these surfaces by painting the surface with colors that represent its local “malleability” (deformation property values) and to interactively deform this surface into the desired shape. The deformation property values dictate to what degree the surface is allowed to change locally. For this, we have extended a real-time deformation algorithm (ChainMail) to operate on inhomogeneous meshes with per-vertex deformation property. Both, painting and deforming are part of a larger system for haptic-visual mesh manipulation, in which we explore combinations of bimanual, touch-enhanced virtual tools for interactions with 3D geoscience data.

Using Deformation Map Painting for Bimanual, Haptic Sculpting of 3D Digital Models
We explore a novel interaction technique using forcefeedback devices for creative manipulation of 3D models that combines interactive mesh deformation with painting a deformation property map. Painting a deformation map permits the artist to easily assign different values of “malleability” to specific areas of the model in order to locally manipulate the deformation behavior during interactive ...

This paper presents a unique modeling paradigm for hapticsbased editing on point set surfaces. In essence, the proposed technique leads to a novel methodology that collectively takes advantage of the potential of implicit surfaces, the strength of physics-based modeling techniques, the simplicity of point sampled surfaces, and the realm of haptic feedback. In particular, the point set surface i...
متن کاملInteractive Haptic Rendering of Deformable Surfaces Based on the Medial Axis Transform
We present a new method for interactive deformation and haptic rendering of viscoelastic surfaces. Objects are defined by a discretized Medial Axis Transform (MAT), which consists of an ordered set of circles (in 2D) or spheres (in 3D) whose centers are connected by a skeleton. The skeleton and physical properties of the object, including the radii of the spheres centered on the skeleton and ma...

We present an intuitive 3D interface for interactively editing and painting a polygonal mesh using a force feedback device. An artist or a designer can use the system to create and refine a three-dimensional multiresolution polygonal mesh. Its appearance can be further enhanced by directly painting onto its surface. The system allows users to naturally create complex forms and patterns not only...
متن کاملExpressive cutting, deforming, and painting of three-dimensional digital shapes through asymmetric bimanual haptic manipulation
Practitioners of the geosciences, design, and engineering disciplines communicate complex ideas about shape by manipulating three-dimensional digital objects to match their conceptual model. However, the two-dimensional control interfaces, common in software applications, create a disconnect to three-dimensional manipulations. This research examines cutting, deforming, and painting manipulation...
