Kinect 3D camera used to create realtime water simulation (by BizarBin)

In this amazing video you see a sandbox equipped with a Kinect 3D camera and a projector used to create a real-time colored topographic map with contour lines onto the sand surface. The sandbox lets virtual water flow over the surface using a GPU-based simulation of the Saint-Venant set of shallow water equations.

The UC Davis W.M. Keck Center for Active Visualization in the Earth Sciences built this for an NSF-funded project on informal science education. These AR sandboxes will be set up as hands-on exhibits in science museums, such as the UC Davis Tahoe Environmental Research Center (TERC) or Lawrence Hall of Science.

Project home page: http://idav.ucdavis.edu/~okreylos/ResDev/SARndbox

The sandbox is based on the original idea shown in this video: http://www.youtube.com/watch?v=8p7YVqyudiE

The water flow simulation is based on the work of Kurganov and Petrova, “a second-order well-balanced positivity preserving central-upwind scheme for the Saint-Venant system.” (via POPSCI)

The image above shows the eastern part of Grand Canyon National Park in northern Arizona, near 36 degrees north latitude and 112.1 degrees west longitude. It is a composite of two pieces: a synthetic natural color image captured on July 14, 2011, draped over a three-dimensional model of the area. The images and stereoscopic data behind the model were acquired by the Advanced Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra spacecraft. The perspective is from east to west, looking down the channel of the Colorado River. North is to the right. In this view, the canyon spans 9 miles (14.5 kilometers) at its widest point and 5,600 feet (1,707 meters) from rim to river bed. The North Rim and Walhalla Plateau stand out on the right side, while Grand Canyon Village rests on the high plateau at upper left. (vía NASA Earth Observatory)

planetsci: I’m going to try something new on the Planetary Science Tumblelog today: 3D Thursday! Space Missions take lots of pictures and they often take them close together. By overlapping two close images, we can make an anaglyph. Since Space is full of 3D stuff, we have lots to cover. Today PlanetSci will bring you two anaglyphs from Mars with NASA’s HiRISE Imager. So get out your red-cyan glasses! This beautiful image shows Yardangs, which are created on Earth as wind carves sandstone into tall mounds. Even if you don’t have 3D specs, you should still check this picture out in 2D! (Image Credit: NASA/JPL/University of Arizona)

Autodesk Labs: Project Photofly 2.0 Louise Leakey Suidae (by Autodesk)

Project Photofly can be used to create 3D models from 2D digital photographs - such as this fossil of an ancient warrior pig. Colleagues from across the globe can then take measurements from the model without having to physically handle the fossil.

Amazing free, easy to use software.

Exploring the El Mayor-Cucapah Fault Rupture Using LiDAR Viewer (by spelunkerucd)

3D recording of a geology PhD student interacting with a high-resolution 3D topography model showing the surface rupture of the April 2010 El Mayor-Cucapah earthquake in Baja California. The application is LiDAR Viewer on a low-cost 3D TV immersive virtual reality environment, and the session was recorded with two Kinect 3D cameras.

This is seriously awesome.

In Flying Monsters 3D, Sir David Attenborough the world’s leading naturalist, sets out to uncover the truth about the enigmatic pterosaurs, whose wingspans of up to 40 feet were equal to that of a modern day jet plane. The central question and one of the greatest mysteries in palaeontology is: how and why did pterosaurs fly? How did creatures the size of giraffes defy gravity and soar through prehistoric skies?

This image shows the Mississippi flood plain in 3D, the low-lying areas forming a broad area on the Louisiana and Mississippi sides of the river. Dark areas are low-lying whereas light blue colors indicate areas of high elevation. The data for this visualization comes from the Shuttle Radar Topography Mission carried out by the space shuttle Endeavour during an 11-day mission in February 2000.

Mt. Ruapehu, New Zealand (by NASA Goddard Photo and Video) All around the world, people live in places where the threat of natural disaster is high. On the North Island of New Zealand, the Mount Ruapehu volcano is just such a threat. A towering, active stratovolcano (the classic cone-shaped volcano), snow-capped Ruapehu Volcano is pictured in this enhanced-color image. The image is made from topography data collected by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on February 11, 2000, and imagery collected by the Landsat satellite on October 23, 2002. Credit: NASA/GSFC/Landsat/SRTM.
