In this paper, the interaction of our novel hyper-redundant haptic display ViSHaRD10 with virtual deformable objects is investigated. ViSHaRD10 has serial kinematic structure and 10 degrees of freedom. The work mainly represents benchmark tests for this novel display. Additionally it aims to create easy-to-use virtual deformable objects. Two different deformable objects were developed. The defo...

We describe a method to obtain the fraction of poorly deformable red blood cells in a blood sample from the intensity pattern in an ektacytometer. In an ektacytometer red blood cells are transformed into ellipsoids by a shear flow between two transparent cylinders. The intensity pattern, due to a laser beam that is sent through the suspension, is projected on a screen. When measuring a healthy ...

E cient and powerful topologically adaptable deformable surfaces can be created by embedding and de ning discrete deformable surface models in terms of an A ne Cell Decomposition (ACD) framework. The ACD framework, combined with a novel and original reparameterization algorithm, creates a simple but elegant mechanism for multiresolution deformable curve, surface, and solid models to \ ow" or \g...

Presented in this paper is the development of a 4096 element continuous membrane deformable mirror under development for the Gemini Planet Imaging instrument designed for extra solar planet detection. This deformable mirror will enable the next generation of adaptive optics (“Extreme” AO) capable of achieving contrasts of up to 10, required to detect these planets that are obscured by the brigh...

This paper introduces the Radial Elements Method – REM for the simulation of deformable objects. The REM was conceived for the real time, dynamic simulation of deformable objects. The method uses a combination of static and dynamic approaches to simulate deformations and dynamics of highly deformable objects. The real time performance of the method and its intrinsic properties of volume conserv...

Deformable models are used in many computer graphic and animation applications, such as virtual environments, video games, medical simulations, and engineering analysis. Techniques for simulating deformable objects often require a mesh of discrete, tetrahedral elements that represent the object being modeled. This paper describes the implementation of a fast and robust method to generate a tetr...

In this paper we describe a test-bed we have developed for simulation of abdominal trauma surgery. The abdominal surgery scene is highly complex and contains many layers of deformable organs. Representing this layered and deformable anatomy with models that can interact, be probed and cut presents a unique challenge. We have met this challenge by applying a variety of technology advances in def...

Deformable models often require some degree of user-interaction to produce an accurate segmentation of the feature object. We propose an automatic deformable surface for segmenting the femur from magnetic resonance volumes of the knee. In order to overcome the limitations of many existing deformable models, probabilistic labelling is used to drive the deformation process, together with a surfac...

Contact involving soft materials often combines dry adhesion, sliding friction, and large deformations. At the local level, these three aspects are rarely captured simultaneously, but included in theoretical models by Mergel et al., (2019). We here develop a corresponding finite element framework that captures 3D finite-strain contact of two deformable bodies. This is suitable to investigate fr...
