Direct Manipulation of feature models using Handles
نویسندگان
چکیده
In feature based systems support for direct manipulation is not commonly available. This is partly due to the strong reliance of feature modelling systems on constraints and on the lack of speed of current constraint solv ers. In this paper an approach to the optimization of the geometric constraint solving for the specific situation of direct manipulation is described. Also a solution for a direct manipulation interface was designed that brings to feature modelling the advantages of direct manipulation while taking into account the main feature model ling paradigm concepts. Details are provided on how it was implemented successfully in the SPIFF feature mod elling system.

Advanced direct manipulation of feature models
In current commercial feature modelling systems, support for direct manipulation of features is not commonly available. As a result, re-designing is time-consuming due to the inefficient feedback, the insight given is rather poor, and user interaction often lacks intuitiveness. This is partly due to the lack of speed of current constraint solvers, but also to deficient interactive facilities. I...
متن کاملDirect GPU-based Volume Deformation
Fast and realistic soft-tissue deformation is an important feature for medical simulation environments. In this work we present a direct deformation approach for volumetric datasets which is completely performed on the GPU. It takes on the one hand advantage of a GPU's computing power; on the other hand deformation is easily combined with hardware-supported rendering. Our deformation technique ...
متن کاملSensitivity Analysis of Coulomb and HK Friction Models in 2D AFM-Based Nano-Manipulation: Sobol Method
Nanotechnology involves the ability to see and control individual atoms and molecules which are about 100 nanometer or smaller. One of the major tools used in this field is atomic force microscopy which uses a wealth of techniques to measure the topography and investigates the surface forces in nanoscale. Friction force is the representation of the surface interaction between two surfaces an...
متن کاملModeling and Simulation of Spherical and Cylindrical Contact Theories for Using in the Biological Nanoparticles Manipulation
The low Young's modulus of biological particles results in their large deformation against the AFM probe forces; therefore, it is necessary to study the contact mechanics of bioparticles in order to predict their mechanical behaviors. This paper specifically deals with the contact mechanics of DNA nanoparticles with spherical and cylindrical shapes during manipulation. In previous studies, ...
متن کاملFeature-preserving Direct Blue Noise Sampling for Surface Meshes
We present a new direct Poisson disk sampling for surface meshes. Our objective is to sample triangular meshes, while satisfying good blue noise properties, but also preserving features. Our method combines a feature detection technique based on vertex curvature, and geodesic-based dart throwing. Our method is fast, automatic, and experimental results prove that our method is well-suited to CAD...
