A First Look
There’s no denying that the Pre-alpha SDK is exactly what it says on the box, a pre-alpha, that said there’s a surprising amount of useful functionality which can be gleaned from looking deeper into the C# samples that are present and taking lessons learnerd from previous SDKs.
First off, the kit includes a Unity3D sample (there is just the one in the current package) is the Nine Cubes sample within the frameworks folder of the samples directory structure.
This gives us a good starting point to look into how to take advantage of the camera & SDK, although a few red-herrings are present which may be hangover from development versions, it gave us enough of an idea to further explore and adapt some of the separate C# samples bringing that functionality into our initial Unity3D project. (CS: We use Unity3D almost exclusively here at Soma Games so having this bridge to RalSense was a practical pre-requiste for us to consider adoption of RealSense)
For this exercise we were primarily concerned with being able to track & record finger joint positioning within Unity3D. The available methods and documentation suggest there is an planned ability to load, save, and recognize gestures from a pre-defined library but after a little digging and running questions up to the dev team it appears that feature has been ‘delayed’ 🙁 So with our hopes dashed at not finding the C# gesture viewer sample we wanted to see how, or even if, we would be able to access the joints to explore developing our own approach to logging finger & hand poses.
