Shape Improvement of Surfaces

چکیده
An automatic and local fairing algorithm for bicubic Bspline surfaces is proposed. A local fairness criterion selects the knot, where the spline surface has to be faired. A fairing step is than applied, which locally modi es the control net by a constrained least-squares approximation. It consists of increasing locally the smoothness of the surface from C to C. Some extensions of this method are also presented, which show how to build further methods by the same basic fairing principle.

متن کاملA Novel Multimode Mobile Robot with Adaptable Wheel Geometry for Maneuverability Improvement
In this paper, an innovative mobile platform is presented which is equipped by three new wheels. The core of the new idea is to establish a new design of rigid circular structure which can be implemented as a wheel by variable radius. The structure of wheel includes a circular pattern of a simple two-link mechanism assembled to obtain a wheel shape. Each wheel has two degrees of freedom. The fi...
متن کاملMechanism of Improvement of Formability in Pulsating Hydroforming of T-shape Tubes
In this paper, the mechanism of improvement of formability in pulsating hydroforming of T-shape tubes is investigated by the finite element simulation and experiment. It is shown that local thinning was prevented by oscillating the internal pressure, because the protrusion is formed gradually by the prevention of sharp bulging. In the hydroforming, for the pulsating pressure, several steps occu...

This study presents an optimization problem for shape design of a 2-D radiant enclosure with transparent medium and gray-diffuse surfaces. The aim of the design problem is to find the optimum geometry of a radiant enclosure from the knowledge of temperature and heat flux over some parts of boundary surface, namely the design surface. The solution of radiative heat transfer is based on the net r...
متن کاملModelling Objects Having Quadric Surfaces Incorporating Geometric Constraints
This paper deals with the constrained shape reconstruction of objects having quadric patches. The incorporation of geometric constraints in object reconstruction was used rst by Porrill 10]. His approach combined the Kalman lter equations with linearized constraint equations. This technique was improved by De Geeter et al 5] to reduce the eeects of linearization error. The nature and the specii...
متن کاملSurface reconstruction of detect contours for medical image registration purpose
Although, most of the abnormal structures of human brain do not alter the shape of outer envelope of brain (surface), some abnormalities can deform the surface extensively. However, this may be a major problem in a surface-based registration technique, since two nearly identical surfaces are required for surface fitting process. A type of verification known as the circularity check for th...
