We introduce a new collision response scheme that handles collisions between deformable objects with triangulated surfaces. Based on internal forces and penetration depth information, the approach computes the contact surface of interpenetrating objects. In particular, we address discontinuity problems that arise in discrete-time simulations with coarse surface representations. The approach is ...

When a vector field in R is discontinuous on a smooth codimension one surface, it may be simultaneously tangent to both sides of the surface at generic isolated points (singularities). For a piecewise-smooth dynamical system governed by the vector field, we show that the local dynamics depends on a single quantity—the jump in direction of the vector field through the singularity. This quantity ...

[1] We present a model for the study of the effect of rheological hysteresis on compaction in sedimentary basins, when surface loading and unloading occurs. When compaction is slow (sedimentation rate is large and/or permeability is small), the hysteresis has little effect on the basal compaction layer, but in the more realistic case where compaction is fast (i.e., sedimentation is slow and/or ...

For convenience, let us rewrite v(x,y) as a function of three parameters v(dc,don, p): the compressed discontinuity dc, the oriented normalized discontinuity don, and the relative coordinates of the screen-space pixel in the projected light space p. For the parameters dc and p, the description given in the Section 3.1 of the paper is sufficient for this supplementary document. However, we need ...

This paper is partly born of an increasing sense of uncertainty about how to do syntax. Time was, we linguists had at our disposal a generally accepted arsenal of analytic devices to deal with a familiar range of constructions and phenomena. However, as the phenomena under study began to proliferate, so did the analyses. The increasingly baroque GB architecture began to collapse under the weigh...

The 41 0-kilometer seismic discontinuity is generally considered to be caused by a phase transformation of the main constituent of the upper mantle, olivine, ot-(Mg,Fe)2SiO4, to P-(Mg,Fe)2SiO4. Recent data show that H20 dissolves in olivine and other nominally anhydrous mantle minerals and that the partitioning of H20 between olivine and P-(Mg,Fe)2Si04 is about 1:10. Such behavior strongly affe...

results of velocity structure modeling in the earth's crust using a comparison approach of receiver function analysis and joint inversion of receiver functions with surface wave dispersion data are presented in this paper. seismograms of the teleseismic events that have been recorded on a broadband seismic station in the central alborz were used for data processing. velocity models that we...

We present three methods for texturing point models from sample textures. The first method, the point parameterization method, uses a fast distortion-bounded parameterization algorithm to flatten the point model’s surface into one or more 2D patches. The sample texture is mapped onto these patches and alpha blending is used to minimize the discontinuity in the gaps between the patches. The seco...
