Creating Ambient Occlusion with transparency texture– Tutorial In my previous post Dissecting the mib_amb_occlusion node. I talked about using transparency in Ambient occlusion, but I didn’t really cover the subject of using texture with alpha and having that casing AO on the nearby object. In this simple scene we have a texture file with alpha assigned to a separate geometry. If we would to render, we get this result. A regular AO pass would look something like so This in theory is accurate, since ambient occlusion doesn’t recognize alpha in texture files.

ESRI Geo-tagged Tweets It seems the ever evolving Geo Viewer from ESRI (recall the Flex viewer that ESRI has been building on all week) now incorporates the ability to search and display Geo Tagged Tweets. Using the app, select the Tools icon (cube), then select the Twitter Option. This reveals a Twitter results box in the lower right region. Then select the "Draw Search Area" option (purple circle) and click on an area on the map dragging the mouse to create a radial search region. Resulting tweets that are geo tagged within the area will be displayed. One has to wonder that if communications permitted, individuals that require assistance could be sending geo located Twitter Tweets quickly and easily via their mobile, enabling relatively accurate location of those needing help.
Intro to Emergent Urbanism Mathieu Helie has been writing at a blog he calls Emergent Urbanism. His most recent post is the first part of a series that will be published as an entire article entitled “The Principles of Emergent Urbanism” at International Journal of Architectural Research. This first part of the series, and hopefully the entire published article gives a great introduction to the concept Helie names “Emergent Urbanism.” In my opinion as a Market Urbanist, Mathieu’s most remarkable contributions to urbanism revolve around the concepts of “emergence” as it relates to urban patterns, particularly with regards to Hayek’s ideas about “emergent order” or “spontaneous order”. As Mathieu writes: How is it possible for what is obviously a human artifact to arise as if by an act of nature?
Day length & GPS coords The 8.9-magnitude quake in Japan will not only leave an everlasting impression on the country, but globally as a result of the quake’s effect on the rotation of the Earth and GPS coordinates. Incredibly, the earthquake in Japan was so powerful it sped up the rotation of the Earth resulting in the shrinking of a 24-hour day by 1.8 milliseconds. The estimate comes from Richard Gross who is based at NASA‘s Jet Propulsion Laboratory in Pasadena, California. Gross’ estimate could change as additional data about the quake is gathered. He had recently stated that the day shrank by 1.6 milliseconds, but has since updated the original estimate based on new information. How could an earthquake speed up the Earth’s rotation? 100 Creative Packages for 2010 Details April 18, 2010 by Tom McCracken
Poster of the Great Tohoku Earthquake (northeast Honshu, Japan) of March 11, 2011 - Magnitude 9.0 Tectonic Summary The magnitude 9.0 Tohoku earthquake on March 11, 2011, which occurred near the northeast coast of Honshu, Japan, resulted from thrust faulting on or near the subduction zone plate boundary between the Pacific and North America plates. At the latitude of this earthquake, the Pacific plate moves approximately westwards with respect to the North America plate at a rate of 83 mm/yr, and begins its westward descent beneath Japan at the Japan Trench. Helping Haiti respond to the earthquak (Cross-posted from Official Google Blog) These recent satellite images of Port-au-Prince, Haiti before and after Tuesday's earthquake dramatically show the devastation caused by magnitude 7.0 trembler. Here are before-and-after screenshots of the National Palace and an area of Port-au-Prince: Click to see full-size
Emergent Urbanism, or ‘bottom-up planning’ I was asked to write an article around ‘bottom-up planning’ by Architectural Review Australia a while ago. It was published in the last issue, and I’m re-posting here. ‘Bottom-up’ is hardly the most elegant phrase, but I suspect you know what I mean. UNOSAT supports crowd sourcing community Geneva 14 March 2011. The aftermath of the catastrophic quake and tsunami in Japan has mobilised unprecedented participation from social networks and crowd sourcing communities around the world. Satellite imagery released for free by major commercial satellite companies earlier this week revealed to the world the extent of the impact of the tsunami waves that hit the east coast of Japan on Friday 11 March.
3D printing 'Factory of the Future' opens in NYC 3D printing is changing the way creatives can make their designs and ideas a reality, and it's taken another big leap forward, with 3D printing marketplace and community Shapeways cutting the ribbon on its new 'Factory of the Future'. Based in New York and billed to be the world's largest 3D printing factory, it will house 30 to 50 high definition, industrial-sized 3D printers, each capable of producing more than 100 products a day and three to five million products a year. Shapeways' director of industrial engineering Kegan Fisher comments on its website: "We are building a factory that gives everyone the ability to create, where the only barrier to entry is imagination." We are building a factory where the only barrier to entry is imagination The 3D printing facility will have more than 50 engineers, craftsmen, 3D printing specialists, and industrial designers to ensure everything runs smoothly.
Japan earthquake: Interactive map tracks the foreshocks and aftershocks of the 9.0 magnitude quake that struck March 11, 2011 The magnitude 9.0 earthquake that rocked Japan on March 11 at 2:46 p.m. struck after a series of smaller quakes earlier in the week. Aftershocks — as many as 12 to 15 an hour — now total in the hundreds, including more than 30 of magnitude 6 or greater. Play the timeline map below to see quakes magnitude 5 and greater before and after the strongest temblor to strike Japan in 140 years.
