This paper describes a method for building interpolating or approximating implicit surfaces from polygonal data. The user can choose to generate a surface that exactly interpolates the polygons, or a surface that approximates the input by smoothing away features smaller than some user-specified size. The implicit functions are represented using a moving(More)
This paper describes a real-time technique for generating realistic and compelling sounds that correspond to the motions of rigid objects. By numerically precomputing the shape and frequencies of an object's deformation modes, audio can be synthesized interactively directly from the force data generated by a standard rigid-body simulation. Using(More)
Modal analysis provides a powerful tool for efficiently simulating the behavior of deformable objects. This paper shows how manipulation, collision, and other constraints may be implemented easily within a modal framework. Results are presented for several example simulations. These results demonstrate that for many applications the errors introduced by(More)
—Tag services have recently become one of the most popular Internet services on the World Wide Web. Due to the fact that a web page can be associated with multiple tags, previous research on tag recommendation mainly focuses on improving its accuracy or efficiency through multi-label learning algorithms. However, as a web page can also be split into(More)
Errors indicate the need to adjust attention for improved future performance. Detecting errors is thus a fundamental step to adjust and control attention. These functions have been associated with the dorsal anterior cingulate cortex (dACC), predicting that dACC cells should track the specific processing states giving rise to errors in order to identify(More)
This technical sketch describes how a standard analysis technique known as modal decomposition can be used for real-time modeling of viscoelastic deformation. While most prior work on interactive deformation has relied on geometrically simple models and advantageously selected material parameters to achieve interactive speeds, the approach described here(More)
From pouring sauces to sudsy sink water to violent sewer rapids, realistic animation of fluids presented interesting challenges in Rata-touille. The various fluid effects were simulated either using a physically-based solver or directly with generic particle systems. Although the simulated particles move as a whole like a fluid, the number of particles was(More)
