Exact and efficient computation of moments of free-form surface and trivariate based geometry
نویسندگان
چکیده
Two schemes for computing moments of free-form objects are developed and analyzed. In the ®rst scheme, we assume that the boundary of the analyzed object is represented using parametric surfaces. In the second scheme, we represent the boundary of the object as a constant set of a trivariate function. These schemes rely on a pre-computation step which allows fast re-evaluation of the moments when the analyzed object is modi®ed. Both schemes take advantage of a representation that is based on the B-spline blending functions. q 2002 Elsevier Science Ltd. All rights reserved.

Computing Moments of Piecewise Polynomial Surfaces
Combining the advantages of a low-degree polynomial surface representation with Gauss' divergence theorem allows efficient and exact calculation of the moments of objects enclosed by a free-form surface. Volume, center of mass and the inertia tensor can be computed in seconds even for complex objects with 105 patches while changes due to local modification of the surface geometry can be compute...
متن کاملExact analytical approach for free longitudinal vibration of nanorods based on nonlocal elasticity theory from wave standpoint
In this paper, free longitudinal vibration of nanorods is investigated from the wave viewpoint. The Eringen’s nonlocal elasticity theory is used for nanorods modelling. Wave propagation in a medium has a similar formulation as vibrations and thus, it can be used to describe the vibration behavior. Boundaries reflect the propagating waves after incident. Firstly, the governing quation of nanoro...
متن کاملA Note on Solving Prandtl's Integro-Differential Equation
A simple method for solving Prandtl's integro-differential equation is proposed based on a new reproducing kernel space. Using a transformation and modifying the traditional reproducing kernel method, the singular term is removed and the analytical representation of the exact solution is obtained in the form of series in the new reproducing kernel space. Compared with known investigations, its ...
متن کاملTrivariate B-spline Approximation of Spherical Solid Objects
Recently, novel application areas in digital geometry processing, such as simulation, dynamics, and medical surgery simulations, have necessitated the representation of not only the surface data but also the interior volume data of a given 3D object. In this paper, we present an efficient framework for the shape approximations of spherical solid objects based on trivariate B-splines. To do this...
