Designing curved folds of a developable surface remains an open problem. No analytical method for the design of curved folds has been reported. Although optimization methods exist, it is difficult to interactively design valid curved folds of a single developable surface using such methods. In the present paper, we propose an interactive system for designing a surface with planar curved folds b...

The authors investigate the effects of cloud–radiation interaction and vertical wind shear on convective ensembles interacting with large-scale dynamics in cloud-resolving model simulations, with the large-scale circulation parameterized using the weak temperature gradient approximation. Numerical experiments with interactive radiation are conducted with imposed surface heat fluxes constant in ...

Interaction sounds when tapping on a surface provide information about the material of the surface and about one’s own motor behaviour. With the current developments in interactive sonification, it is now possible to digitally change this audio-feedback resulting from object interaction. Here we evaluated a model for a sonic interactive surface. This model uses a system capable of delivering su...

Point-based rendering methods have proven to be effective for the display of large point cloud surface models, basically replacing global surface reconstruction with local surface estimations, for example, via splats or implicit functions. Crucial to their performance in terms of rendering quality and speed is the representation of the local surface patches. We present an approach that avoids a...

Subdivision surfaces have become a standard technique for freeform shape modeling. They are intuitive to use and permit designers to flexibly add detail. But with larger control meshes, efficient adaptive rendering techniques are indispensable for interactive visualization and shape modeling. In this paper, we present a realization of tesselation-on-the-fly for Loop subdivision surfaces as part...

We present a prototype large-scale interactive electronic whiteboard wall. Various input, output and vision technologies are used to create a surface that can capture digital ink as well as support pen-based interaction with displayed information on subregions of the wall. A simple automated capture application is demonstrated on our prototype surface and research challenges for developing more...

In this paper, a new technique is presented for interactive rendering of caustics fully processed on GPU. Without any pre-computation required, the algorithm can directly render refractive caustics from complex deformable transparent objects onto an opaque receiver surface. By the technique we accurately trace the path of the photons and calculate the energy carried by the photons emitted from ...
