Fitting of Iso-Surfaces Using Superquadrics and Free-Form Deformations
Recovery of 3-D data with simple parametric models has been the subject of many studies over the last ten years. Many have used the notion of superquadrics introduced for graphics in Bar81]. Diierent improvements were introduced to make the model a better representation of the data BG87, FLW89, SB90, TM91]. This paper describes a two-steps method to t a parametric deformable surface to 3-D poin...
متن کاملMinimum Zone Evaluation of the Form Errors of Quadric Surfaces
Quadric surfaces commonly exist in natural objects and artificial components. It is widely needed to evaluate the form quality of a measured data set, but the mostly used least squares method will lead to over-estimation and its results are not consistent with the definitions in ISO standards. In this paper a shape recognition approach is presented to determine the surface type and shape parame...
متن کاملSkinning Characters using Surface Oriented Free-Form Deformations
Skinning geometry effectively continues to be one of the more challenging and time consuming aspects of character setup. While anatomic and physically based approaches to skinning have been investigated, many skinned objects have no physical equivalents. Geometric approaches, which are more general and provide finer control, are thus predominantly used in the animation industry. Free-form defor...
متن کاملCost Analysis of Acceptance Sampling Models Using Dynamic Programming and Bayesian Inference Considering Inspection Errors
Acceptance Sampling models have been widely applied in companies for the inspection and testing the raw material as well as the final products. A number of lots of the items are produced in a day in the industries so it may be impossible to inspect/test each item in a lot. The acceptance sampling models only provide the guarantee for the producer and consumer that the items in the lots are acco...
متن کاملExtended annular capillary surfaces
The height of the surface of a fluid in an annular tube is explored using a shooting method to solve a boundary value problem where the radii and the contact angles are given. The contact angles on the inner and outer tube surface need not be the same. These surfaces are then extended so that they are no longer graphs. The extended surfaces are shown to solve a boundary value problem over an an...
