OpenGL @ Lighthouse 3D - Terrain Tutorial This algorithm is a very simple one, yet its results, although not the best, are pretty good. The technique is not limited to planar height fields, being also applicable to spheres to generate artificial planets. Paul Bourke and Hugo Elias have posted tutorials on the application of this algorithm to spheres. To start with we'll have a planar height field, where all points have zero height. Orbital Piloted Assembly and Experiment Complex, OPSEK Above: Artist rendering of the proposed orbital assembly workshop, the successor to the ISS, as it was envisioned around 2008 by Russian engineers. Instead of being a research lab, the new station was conceived as an assembly point for missions to Mars and lunar expeditions. Russia's next-generation transport ship can be seen approaching on the left. Copyright © 2009 Anatoly Zak A concept of the Russian successor to the ISS Russian-American cooperation on the development of the International Space Station, ISS, created great hopes for the future of the manned space program, but also left a bad taste in the mouth of both sides.

3 New Resources for Science Teachers June 27, 2015 Here are three more resources for science teachers and students. These resources are featured here for the first time. The first one in the list, Mystery Science, is particularly helpful for elementary teachers seeking science lesson plans and activities to use with students in class. The rest are iPad apps students can use to enhance their science learning in different aspects that include: vocabulary, games, quizzes, hands-on activities and many more. 1- Mystery Science Volume Workflows Used as a hint as to whether the volume should compute indirect illumination inside the volume (also known as multiple scattering, because light will scatter more than once inside the volume). If the multi scatter parameter is set to 0, and the integrator respects this hint, PxrVolume will only perform single scattering: points inside the volume will only be lit directly by light sources. If set to 1, points inside the volume will be lit by indirect illumination as well.For very dense volumes with high anisotropy, it is often the case that light will scatter many times inside the volume before reaching the eye, and multiple scattering is the only way to achieve the correct look. It is also often the only way to correctly render certain effects such as volume caustics.

Space Exploration Systems Dawn of a Dream Meet the Dream Chaser® – a winged, lifting-body spacecraft that provides a flexible, credible, affordable solution for ISS crew transportation and a viable path to the future of human space flight operations for NASA, international and commercial space applications. Dream Chaser is the product of a dynamic collaboration among well-known, well-established industry leaders, experts and universities. SNC is currently working with NASA's Commercial Crew Program to develop and configure Dream Chaser for International Space Station servicing. Spicing Up Student Learning With History and STEM Podcasts Podcasts have been around for a long time now, but they have only just begun to surge into mainstream popularity. That’s all thanks to a little podcast called Serial, a true crime program that reopened investigation into the murder of a high school student committed in 1999. With tens of millions of downloads, this podcast is officially the most popular of all time. To those of us who are longtime podcast fans, the potential of the medium to both captivate and set minds whirring is no surprise. And it’s those two things that make podcasts pretty much the perfect medium for learning, whether in the classroom, at-home, or as student commute from sports practice to band practice to home There are so many great podcasts out there, that we found we couldn’t narrow them all down into one article.

Grand Tour: Project Overview Tags : RMS 19, physically plausible shaders, image based lighting, gpsurface, glass, volumes, character, hair, fur, primvars, PTEX, vector displacements In this eight chapter "How To" guest contributor Leif Pedersen will break down a production pipeline in RenderMan Studio and RenderMan Pro Server. We will specifically focus on the advantages of RMS and how it can help us decrease setup time without compromising efficient render times. We will divide the training into two distinct approaches to rendering via RenderMan Studio's RIS and REYES rendering architectures. The training will cover the interactions between RMS and Maya for general rendering workflows, Mudbox and Zbrush for importing texture and displacement maps, as well as Fusion and Nuke for Compositing. With this in mind, previous experience with these applications is helpful.

10 Animals You Probably Didn't Know Existed - Knowledge Salad We’ve all heard about the flying squirrel, vampire bats, and naked mole rat, but I bet you haven’t heard of Markhor, Lamprey, and Gerenuk! Here are ten animals that you probably haven’t heard of! (Too lazy to write a good introduction!) Gitzo GT1542T Safari Tripod 4sec. - Statieven & Monopods - Foto Gitzo GT1542T Safari Tripod 4sec. GT1542T tripod combines the compactness and light weight of the Gitzo Traveler System with the stability and size of a regular Mountaineer Series 1 tripod. It is dedicated to the high-end user seeking for a highly portable support with no compromise. Groud level set - This new feature allows you to remove the centre column to save weight and get the camera closer to the ground.

HOUDINI OTL : normals on curve! Hi everyone ! Yes that’s true , we are talking about Houdini. I have been a long time Maya user , I started back in 2006! Photographing Textiles I love to photograph my own textiles and here is the method I have devised afer years of trial and error. It’s another good excuse to deeply look at textiles. I like low, natural lighting so I always photograph on a bright but cloudy day. This is more for Australian conditions as the light here is very bright and throws strong, deep shadows. I just set up near a window, which sometimes has to have greaseproof paper taped to it to soften the light.
