pitat450 Once again I immersed myself into the wild waters of rendering engine. In the past I have written a similar tutorial covering some settings in the great YAFARAY raytracer. This time I decided to examine 'CYCLES' which I have grown very fond of lately. It has been around for some time now and it is a great FREE option for an unbiased path-tracer. It was the "Light paths" Rollout in the "Rendering tab" that I was going to examine this time. First some theory. Camera Reflection Transmission Shadow These rays are very closely connected to the type of material surface (or material's shaders). The "Light paths" rollout control the number of bounces for certain types of rays. These values all control the behavior of the light rays in the scene. Bounces Max /Bounces Min(0-1024) These values can be adjusted to limit the number of any kind of ray, be it diffuse, glossy or transmission. Diffuse (0-1024) Diffuse is the basic color of a surface. Glossy (0-1024) Transmission (0-1024) Shadow checkbox
Mars Anomaly Research Home Page Science & Environment - Will we ever... live on the Moon? Four decades after the Apollo missions, the idea of colonising the Moon is still the stuff of science fiction. But astronomer Phil Plait argues that it is not an issue of whether we can live there, but how and why we want to. Will mankind once again walk on the lunar surface? I wouldn’t even hesitate to say “yes”, because the future is long, and who in the early 1950s would have dared to predict that we would even land a craft on the Moon within 20 years? But in this case, the answer probably isn’t as interesting as the question itself – more specifically, when, and why, and how will we do it? I can think of many possible scenarios that could lead to us colonising the Moon: an extended economic boom that allows us to fund ambitious space exploration; a breakthrough in launch costs which makes them drastically cheaper; or the discovery of some vital natural resource on the Moon. A better question is then: “What is a likely way we’ll end up with a human presence on the Moon?” Far from it.
From Geek To Freak: How I Gained 34 Lbs. Of Muscle In 4 Weeks! Vital Stats Name: Timothy Ferriss Age: 29 Weight Before: 146 lbs. Weight After: 177 lbs. (183 three days after last official weighing) Body Fat % Before: 16.72% Body Fat % After: 12.23% Total Muscle Gained: 34 lbs. Supplements Used For This Transformation: Morning: NO-Xplode (2 scoops), Slo-Niacin (or timed-release niacinamide) Each meal: ChromeMate, alpha-lipoic acid (200mg) Pre-workout: BodyQUICK (2 capsules 30 minutes prior) Post-workout: Micellean (micellar casein protein) Prior to bed: policosanol, ChromeMate, alpha-lipoic acid (200mg), Slo-Niacin Why Did I Decide To Do This? I weighed 152 lbs. for four years of high school, and after training in tango in Buenos Aires in 2005, I had withered to 146 pounds. Hence the decision - upon returning the U.S. - to perform an exhaustive analysis of muscular hypertrophy (growth) research and exercise protocols, ignoring what was popular ... to examine the hard science.

Blender 101: The Modifier Encyclopedia There’s too many settings and functions in Blender to remember what each one does. And Google searches often raise more questions than they answer! Introducing the Blender 101 series! The series where we focus on a specific area of blender and show you what each function does. First up… by Anderson Baptisa Ahh the ever growing modifier panel. Which is why I’ve spent the last month, trying out every single modifier and creating examples for each… So let’s tackle each one (starting from left to right). The Modify group Mesh Cache What it does: Applies animations from external files to your objects. Why use it? To transfer a completely rigged character to another 3D application, bake an animation to disk and then play the results (like importing a realflow animation into Blender), or for re-using animations across other meshes like a stadium crowd for example.

Brand New Look at the Face of Mars Photo What really lies across the surface of Mars? Rovers have scurried about the red planet for years, drilling, scooping and analyzing for signs of life, past or present. But to really understand the Martian landscape, scientists need to look at the entire surface. What they have needed is a global geologic map. The red planet is long overdue for a new one. Now, scientists at the United States Geological Survey have used that data to create an updated map of the entire Martian surface. “We are disproportionately interested in the early part of Martian history,” said David Beaty, the chief scientist for the Mars Exploration Directorate at the Jet Propulsion Laboratory in Pasadena, Calif., who was not involved in the research. The project, funded by NASA, was not simply a compilation of photographs from Martian orbit. Continue reading the main story One important instrument was the laser altimeter, which could fire up to 600 million laser beams at a planet’s surface.
Mars Exploration, Astronauts on Mars & 50 Years of Human Spaceflight | Why Aren't Astronauts Living on Mars Yet? | NASA Space Exploration, Human Spaceflight Humanity has been flying in space for 50 years now, but we are still confined to a single planet — Earth. If it took only eight years to go from no humans in space to the first man on the moon, why haven't humans colonized Mars and other worlds yet? Or at the least the moon? "NASA's plan as of 1969 was to have a human Mars mission by 1981, a permanent moon base in the '80s and a permanent Mars base in 1988," said Robert Zubrin, president and founder of the Mars Society. On 12 April 1961, Russian cosmonaut Yuri Gagarin became the first human to travel into space when he launched into orbit on the Vostok 3KA-3 spacecraft (Vostok 1).Credit: ESA Interplanetary human voyages pose definite scientific and technological challenges. Space exploration versus politics Here the re-entry capsule of the Vostok 3KA-3 (also known as Vostok 1) spacecraft (Vostok 1) is seen with charring and its parachute on the ground after landing south west of Engels, in the Saratov region of southern Russia.Credit: ESA
Automate Your Income to Simplify Your Life Every Tuesday is Finance & Family Day at Zen Habits. The title of this post almost looks like the subject of a spam email when I look at it, and yet I’m completely serious — one of the best ways to simplify your life is to put your income on autopilot. It’s not an easy task at first, but once you’ve got it set up, it’s well worth the effort. Instead of working hard to earn money every day and every month, work hard to set up your income stream, and then do minimal work from then on out to maintain that stream. I’ve talked before about how to put your bills and savings on autopilot — now let’s look at how to do the same thing with your income. But in this article, we’ll talk a little about how automating your income can simplify your life, and then look at ways you can go about doing it. Simplify, simplify, simplify On this site we’ve talked a lot about simplification, from simplifying your to-do list to simplifying your closets and everything in between. Creating a business.

updates to my texture library | Ni:Zu vault Below, some test renders of new textures and ‘shaders’ i just made for my texture library, by shader i just mean a texture nodegroup preset : e.g. top and bottom left use the same group ‘peeling plaster’ with different settings :brick color can be changed with a color picker , the ratio of plaster/bricks with a slider (quite simply controls a threshold node on a greyscale mask , allows to have bigger or smaller patches of visible bricks ), the plaster color and spec can be changed (plugging in another preset node) . It’s really handy to prepare such libraries as nodegroups instead of simply loading in pngs each time : to have fancy parameters like those bricks , or even just grouping col/spec/norm in a nice box , and hide some mapping nodes for box mapping scale and world offset , exposing only the useful params. On the right: some base metals, like the brick/plaster combo these are some key materials that you always need and in after project Mango i had a few things in mind to improve.
Unmasking the Face on Mars New high-resolution images and 3D altimetry from NASA's Mars Global Surveyor spacecraft reveal the Face on Mars for what it really is: a mesa. Listen to this story (requires any MP3 Player) May 24, 2001 -- Twenty five years ago something funny happened around Mars. NASA's Viking 1 spacecraft was circling the planet, snapping photos of possible landing sites for its sister ship Viking 2, when it spotted the shadowy likeness of a human face. An enormous head nearly two miles from end to end seemed to be staring back at the cameras from a region of the Red Planet called Cydonia. There must have been a degree of surprise among mission controllers back at the Jet Propulsion Lab when the face appeared on their monitors. Above: A 1976 Viking 1 photograph of the Face on Mars. A few days later NASA unveiled the image for all to see. It certainly did! The "Face on Mars" has since become a pop icon. But not everyone was satisfied. Mission controllers prepared to look again.

Forget Mars. Here's Where We Should Build Our First Off-World Colonies The collective space vision of all the world’s countries at the moment seems to be Mars, Mars, Mars. The U.S. has two operational rovers on the planet; a NASA probe called MAVEN and an Indian Mars orbiter will both arrive in Mars orbit later this month; and European, Chinese and additional NASA missions are in the works. Meanwhile Mars One is in the process of selecting candidates for the first-ever Martian colony, and NASA’s heavy launch vehicle is being developed specifically to launch human missions into deep space, with Mars as one of the prime potential destinations. But is the Red Planet really the best target for a human colony, or should we look somewhere else? Should we pick a world closer to Earth, namely the moon? To explore this issue, let’s be clear about why we’d want an off-world colony in the first place. Creating a Mars Colony First, let’s take a look at what the mooted Mars settlement schemes are offering. Mars colony illustration. The Problem of Distance Close to Home
