Maybe try one of the links below or a search?We talk a lot about working remotely. Over 70% of our employees work remotely. They work out of homes, coffee shops, and co-working spaces. They play music, garden, and spend time with their families. We dig working remotely so much we wrote a book about it. Meet some of the fantastic people who make working remotely for 37signals such a success.So far in this series we've covered the visual and depth inputs and started to look at skeletonization. In this part we get down to the bare bones of the skeleton. The first part is Getting started with Windows Kinect SDK 1.0 If you don't want to miss it subscribe to the RSS feed, follow us on Google+, Twitter, Linkedin or Facebook or sign up for our weekly newsletter. While there is a very good example of how to draw a complete skeleton in the SDK it isn't explained in detail and, in common with most examples, it does things in clever and correct ways.
This makes it a piece of code to admire but only if you can work out what it is doing and how. In this article the objective is not only to create a full skeleton graphic but to make it perfectly clear how it is done. First a small digression into GDI graphics. In the previous examples we have just used direct manipulation of the bit array to set pixels. This is fine when you only want to work with a few pixels and it has the advantage of not involving any other objects. However once you need to start drawing lines to form a skeleton then things are too difficult to work with via direct manipulation. At this point you have to use what ever graphics facilities the framework you are using provides. The problem is that there is a split between Windows Forms and WPF. For this example we are going to use Windows Forms and the GDI because it is closer to the same facility in C++. The key idea in the way that Windows Forms provides the facilities of the GDI is the Graphics object.
This is a wrapper around the underlying operating system graphics used to draw everything you see on the screen.To make use of it you need to create a Graphics object which provides all of the methods you need to draw on that object. Clearly not all objects can be drawn on and not all objects can be associated with a Graphics object - but a Bitmap can. So if you have converted the bit array into a Bitmap you can obtain a Graphic object to enable you to draw on the Bitmap using: Now you can use the drawing methods provided by Graphics to draw on the Bitmap. will draw an ellipse on the bitmap as specified by the Pen and the Rectangle which contains the ellipse. Now that you have seen how this works you can look up the drawing methods of the Graphics object and use them to draw almost anything on the Bitmap. The only methods that we will use in addition to the DrawEllipse method is: which draws a line in the specified Pen from x1,y1 to x2,y2 and which draws a line from Point1 to Point2.
Notice that all of the co-ordinates are in pixels and so as long as we convert Kinect co-ordinates to pixel co-ordinates in the video Bitmap we can just use them to draw. As explained in the previous article, the Kinect doesn't return a skeleton, just a set of joints that it has detected. It is entirely up to us what to do with this set of joints. One of the problems with the example skeleton viewer is that at first look you might think that something clever was going on that relied on the way that the Kinect returns the data. Let's try and draw a skeleton in a step-by-step way that shows how it all works. The instructions that follow just get you to the point where the SkeletonFrameReady methods is called as described in the previous article. Start a new C# Windows Forms project. Make sure you have loaded a reference to the Kinect DLL and add: To the start of the program. In the Form's constructor we create a Runtime object so that we can use the Kinect: The nui variable is global allowing us to get a the Kinect from anywhere in the program - not good design but simpler for an example.
Next we have to setup the Kinect and this is more or less the same for each program, differing in only the facilities we are going to use. In this case we make use of all of the facilities: Next we open the video stream: The Kinect will now return video images from the video camera and skeleton data. To process this data the simplest thing to do is use the two events associated with data ready in each case:The Space Needle is one of the most recognizable landmarks of Seattle, towering above Seattle Center. It stands out quite clearly on the Seattle skyline, looking like something from the Jetsons cartoon, sort of a Flying Saucer on a stick. It has been depicted in several movies and TV shows, a few video games, and they even made a lego set of it. It was designed by Victor Steinbruek, and built for the 1962 Seattle World's Fair (aka the Century 21 Exposition). It was built by the Pentagram Corporation in less than a year. The last elevator car was installed the day before the fair.
At the height of the fair nearly 20,000 people a day rode to the observation deck. Today, it remains a popular tourist site, and is often crowded. At the time of construction, it was the tallest building West of the Mississippi, a title it stole from the Smith Tower across town. 3 people have committed suicide by jumping off it, all in the 1970s. Several other people have climbed out between the safety wires, but been talked back by the police. Six people have parachuted off of it, a sport known as BASE jumping. The two who did so without permission were arrested for it. On May 19, 2007, the 45 Millionth guest won a trip for two to Paris. In June 1987, the Space Needle moved 312 feet (95 m) to the southwest. Officially, This movement only occurred on maps, as the National Oceanic and Atmospheric Administration (NOAA) had begun a 10-year endeavor to re-map the world by satellite images. Major structures and landmarks such as the Space Needle were the first to be mapped out, and the mistake on old maps was discovered in the process.
Stranger things have happened in gaming. The Space Needle is 605 feet (184m) tall, the rough equivalent of 60 stories, though it only has a few floors. The outdoors observation deck, along with a cafe and historical information, can be found at 520 feet (158m). The observation deck is circular, with a 138 foot (42m) diameter. The circumference, should you need to run a lap around it, is about 443 feet (135m). A short wall and a series of guide wires keep people from climbing to their dooms. Several telescopes mounted on the wall allow you a closer look at various parts of the city, and on clear days the Space Needle offers a commanding view of Seattle, it's suburbs, and Puget Sound. The SkyCity restaurant is at 500 feet - it has a dress code, and slowly rotates so you get a view of the entire city. The Skyline Banquet Facility level is at 100 feet, and can be rented for groups of 20 to 360 people. Several large and powerful elevators can take you up. They travel 10mph, taking 43 seconds to get to observation deck.
On windy days, the elevators are slowed to half speed. On the busiest days, the line to get in to the elevators can be an hour long. A ticket to go up costs around $15. Also known as the Skybeam, this 85 million candlepower lamp was added in 1999. It points straight up, and is lit about 12 nights per year. Was originally supposed to be 75 nights a year, but it causes too much light pollution. The foundation alone weighs almost 6,000 US tons (5,443 metric tonnes). It took 467 cement trucks a whole day to fill the hole. It's held to that base by 72 steel bolts, each of which is 30 feet long. The center of gravity is just 5 feet above the ground. It was built to withstand a 9.5 earthquake, or winds up to 200 mph (320 km/h). Ironically, this makes it one of the safest places to be (downtown, anyway) if the big one hit Seattle. The roof of the Space Needle is inhabitated by a big furry creature with a glowing nose. It hates the sound of whistling, so he makes it rain so that your lips are too wet to whistle.
