An Approach to Blend Surfaces
نویسنده
چکیده
In this paper, we present an application of a space mapping technique for surface reconstruction (more precisely: reconstruction of missing parts of a real geometric object represented by volume data). Using a space mapping technique, the surface of a given model, in particular tooth shape is fitted by a shape transformation to extrapolate the remaining surface of a patient's tooth with occurring damage such as a “drill hole.” The genetic algorithm minimizes the error of the approximation by optimizing a set of control points that determine the coefficients for spline functions, which in turn define a space transformation. The fitness function to be minimized consists of two components. First one is the error between the blended surface of an object and the surface of the object to be blended in some predefined points. The second is a component that is responsible for the bending energy being minimized.

Blends of canal surfaces from polyhedral medial transform representations
We present a new method for constructing [Formula: see text] blending surfaces between an arbitrary number of canal surfaces. The topological relation of the canal surfaces is specified via a convex polyhedron and the design technique is based on a generalization of the medial surface transform. The resulting blend surface consists of trimmed envelopes of one- and two-parameter families of sphe...

Procedural Shape Synthesis on Subdivision Surfaces
We present methods for synthesizing 3D shape features on subdivision surfaces using multiscale procedural techniques. Multiscale synthesis is a powerful approach for creating surfaces with different levels of detail. Our methods can also blend multiple example multiresolution surfaces, including procedurally-defined surfaces as well as captured models.
متن کاملTernary blending operations
We discuss new analytical formulations for localized and controllable blending operations in the functionbased solid modeling. The blending set operations are defined using R-functions and displacement functions with the localized area of influence. The shape and location of the blend are controlled by an additional bounding solid thus turning the operation into a ternary one. We also describe ...
متن کاملImplicit Extrusion Fields
This paper presents an implicit function fields based approach for the extrusion of 2-dimensional profiles. According to the fields used, the extrusion follows an implicit object shape or performs the transition between combined primitives. The 1-dimensional polynomial spline properties allow the point-by-point control of the profile. Used on the transition of combined primitives, free form fun...
متن کاملCombining implicit surfaces with soft blending in a CSG tree
In this paper, we show an extension of the model proposed by Sabourdy, combining various implicit surfaces with soft blending capacities in a CSG tree. This extension allows integration of plane surfaces, skeletons and many other types of implicit surfaces. It particularly develops the blending possibilities offered by this approach. The model is then able to generate a wide variety of shapes o...
