Feature-Guided Dynamic Texture Synthesis on Continuous Flows [article]

Rahul Narain, Vivek Kwatra, Huai-Ping Lee, Theodore Kim, Mark Carlson, Ming C. Lin
2007 Symposium on Rendering  
We present a technique for synthesizing spatially and temporally varying textures on continuous flows using image or video input, guided by the physical characteristics of the fluid stream itself.  ...  We also show how our methodology can be extended beyond realistic appearance synthesis to more general scenarios, such as temperature-guided synthesis of complex surface phenomena in a liquid during boiling  ...  These characteristics are derived from the surface properties and velocity fields of continuous flows, obtained from either a simulated liquid animation or pre-recorded video footage.  ...

Cutting a Drop of Water Pinned by Wire Loops Using a Superhydrophobic Surface and Knife

Ryan Yanashima, Antonio A. García, James Aldridge, Noah Weiss, Mark A. Hayes, James H. Andrews, Aristides Docoslis
2012 PLoS ONE  
The driving force for droplet formation arises from the lower surface free energy for two separate drops, and it is modeled as a 2-D system.  ...  An estimate of the free energy change serves to guide when droplets will form based on the variation of drop volume, loop spacing and knife depth.  ...  Still sequences from videos were collected to document the distortion of the upper surface by the superhydrophobic knife in order to compare the profile to an appropriately simple2-D thermodynamic model  ...

2003 Physical Review Letters  
An optical convergent-beam guided-wave technique is used to explore in detail the dynamic flow effects in a twisted nematic cell.  ...  For high fields this twist compression takes the cell far beyond the Mauguin limit and it no longer effectively guides the polarization of the light through the cell.  ...  The authors acknowledge the Engineering and Physical Sciences Research Council of the U.K. for funding this research.  ...
