Programming Kinect

According to the National Instruments example it shows that the kinect uses an index array to get the hand gestures but when connecting the kinect extra class it does not give that option to use the hand for the gestures.

Here is the code for the Cluster VI. This needs no modification to work.

The example code is purely example code, and has two fairly simple examples to look at. The code can be placed into the autonomous loop, and then deployed.

Please give reference to Team 3130, the E.R.R.O.R.'s.

As a side note, you should check out the internal workings of my VI. Now imagine having an index array everywhere that you need a vertex broken out. An unbundle by name works extremely well for this purpose.

You are correct. The Get Kinect Extra VI actually grabs extra data relating to actually tracking. What you use to get the Vertex is the Get Kinect Vertices, and then normally, you use an Index Array to get the actual vertex info. I use my VI, which converts that array into a named cluster, which can then be unbundled.

I'm happy to see that you wrote a converter to a cluster, but there are a few things worth mentioning.

You can grow the index array and it will extract the next element without an enum cluster wired up. That syntax shortcut comes in handy pretty often.

I attached an alternate implementation that keeps the original cluster order (which matches the Microsoft header file), and uses some casting to simplify the diagram. I also attached a typedef for the cluster. Because ctls are not a supported upload type, they are in a zipped folder.

The only reason that I had the enums wired up was because I was not sure as to what the order of the array was going to be, and I wanted them to be in a specific order in the cluster.
If you do not know the order of the array, it is always safer to wire in all of the enums to ensure that the output is the correct value from the array.

But thanks for the code anyways!

Hey Greg, thanks for the converter VI, could be useful but noticed one thing. The array to cluster function was left at the default of 9 elements. It would have to be set to 20 if you want the whole control to be casted.
