Children television productions have been using puppets for a long time. Since the early days of computer animation, computer puppet simulation has been researched intensively. Complex motion capture equipment allows nowadays the real time mapping of movement for virtual puppets (performance animation). However, the costs of capturing equipment are too high and the difference in the workflow ma...

PURPOSE To present outcomes of transurethral removal (TUR) of intravesical or intraurethral mesh after midurethral slings. MATERIALS AND METHODS This was a retrospective chart review of 23 consecutive women: 20 with intravesical mesh and 3 with intraurethral mesh. RESULTS To remove the mesh, transurethral resection with an electrode loop (TUR-E) was used in 16 women and transurethral resect...

We present a method to create virtual character models of real users from noisy depth data. We use a combination of four depth sensors to capture a point cloud model of the person. Direct meshing of this data often creates meshes with topology that is unsuitable for proper character animation. We develop our mesh model by fitting a single template mesh to the point cloud in a two-stage process....

With the increased use of crowd simulation in animation, specification of crowd motion can be very time consuming, requiring a lot of user input. To alleviate this cost, we wish to allow a user to interactively manipulate the many degrees of freedom in a crowd, whilst accounting for the limitation of low-dimensional signals from standard input devices. In this thesis we present two approaches f...

In this paper, nonlinear implicit finite element analyses are used to explore parametric excitation of a bridge stay cable resulting from cyclic motion of the deck. “Parametric excitation” is excitation of a cable mode with deck motion at near twice the frequency of the excited mode. Third-mode parametric frequency response curves are consistently predicted when the finite element mesh is suffi...

To acquire transient response of a drive train, we consider more detailed mathematical model including variable gear mesh. The mesh is represented by the Fourier series. In analysis, gear’s angular velocity considered as constant. It makes sense when steady-state. However, only part which vary according to displacement. should be not series but also modified system establish model, use curve fi...

This paper deals with the implementation of an efficient Arbitrary Lagrangian Eulerian (ALE) formulation for the three dimensional finite element modeling of mode I self-similar dynamic fracture process. Contrary to the remeshing technique, the presented algorithm can continuously advance the crack with the one mesh topology. The uncoupled approach is employed to treat the equations. So, each t...

We study the coupled surface and grain boundary motion in biand tricrystals in three space dimensions, building on previous work by the authors on the simplified two dimensional case. The motion of the interfaces, which in this paper are presented by two-dimensional hypersurfaces, is described by two types of normal velocities: motion by mean curvature and motion by surface diffusion. Three hyp...

Segmenting garments from humanoid meshes or point clouds is a challenging problem with applications in the textile industry and in model based motion capturing. In this work we present a physically based template-matching technique for the automatic extraction of garment dimensions from 3D meshes or point clouds of dressed humans. The successfull identification of garment dimensions also allows...
