In this work, we develop a real-time geometry capture approach to digital face replacement for a dynamic performance. Digital face replacement has major applications in visual effects for motion pictures as well as interactive applications such as video games and simulation and training environments. Our approach looks into extending the 3D face scanning technology developed at the ICT Graphics...

Mineral replacement in rocks consists of growth of guest mineral and dissolution of host. The two reactions are coupled by the grain–grain stress generated by growth of the guest grain in a rigid or very viscous rock in which it has initially no available room. This stress self-adjusts to make the volumetric rates of guest growth and host dissolution equal to each other, which accounts for the ...

The Oligocene–Miocene deposits of the Asmari Formation are located in SW of the Zagros Mountains of Iran. The lower part of the Asmari Formation consists of an evaporite bed that is termed Basal Anhydrite. Seven sections from four different anticlines were selected and sampled for petrographic and mineralogical analyses .The petrographical examinations were carried out using an optical polarize...

Introduction: In planetary environments with stable H2O in the target (Earth, Mars), large impacts will generate extensive hydrothermal systems associated with the ejecta blankets [i.e. 1,2 and references within]. Although the Moon’s crust is considered to be dry by most standards (with the possible exception of the polar deposits), there are textures preserved in the lunar sample collection th...

The geochemistry and textural associations of chondritic phosphate minerals can provide insights into the geological histories parental asteroids, but processes governing their formation deformation remain poorly constrained. Here, we present a quantitative assessment phosphorus-bearing mineral textures in three variously-shocked lithologies (light, dark, melt) Chelyabinsk (LL5) ordinary chondr...
