Sweep-based Freeform Deformations
We propose a sweep-based approach to the freeform deformation of three-dimensional objects. Instead of using a volume enclosing the whole object, we approximate only its deformable parts using sweep surfaces. The vertices on the object boundary are bound to the sweep surfaces and follow their deformation. Several sweep surfaces can be organized into a hierarchy so that they interact with each o...
متن کاملEigen-deformations for elastic matching based handwritten character recognition
Deformations in handwritten characters have category-dependent tendencies. In this paper, the estimation and the utilization of such tendencies called eigen-deformations are investigated for the better performance of elastic matching based handwritten character recognition. The eigen-deformations are estimated by the principal component analysis of actual deformations automatically collected by...
متن کاملLocalized and extended deformations of elastic shells.
The dried raisin, the crushed soda can, and the collapsed bicycle inner tube exemplify the nonlinear mechanical response of naturally curved elastic surfaces with different intrinsic curvatures to a variety of different external loads. To understand the formation and evolution of these features in a minimal setting, we consider a simple assay: the response of curved surfaces to point indentatio...
متن کاملElastic secondary deformations by vector field integration
We present an approach for elastic secondary deformations of shapes described as triangular meshes. The deformations are steered by the simulation of a low number of simple mass-spring sets. The result of this simulation is used to define time-dependent divergence-free vector fields whose numerical path line integration gives the new location of each vertex. This way the deformation is guarante...
متن کاملUnderstanding Perception of Simulated Elastic Deformations
In this project, my goal was to enhance the understanding of human perception of computationally simulated elastically deforming objects. Control parameters for existing computational models of elastic materials do not map intuitively to visually salient properties of elastic objects and phenomena, which makes their use by non-experts difficult. I conduct a set of two exploratory perceptual stu...
