I want to attach the controller to a device that is normally no more than 3" from the palm-side of the hand. But, I notice from my own experiments that when I present a "flat" hand at this distance, the fingers appear "slightly curled" and only "straighten out" when I increase this distance to about 8" or 12". I can live with this situation, but I was just wondering if this minimal "good tracking" distance was set by an adjustable field of view setting in the SDK.
I also have some questions about the IR-transparent glass window. Could it be removed in an environment with no light in the "visible" range?
Another more pressing question I have is:
Could the device track accurately if there were 1 or 2 thin, IR-transparent layers of high-optical-purity glass or plexi-glass between the controller and the hand - with or without the built-in controller's own IR-transparent glass window?
My final question is:
Is there some legacy, Unity C# code to record controller data (to make a 3D hand movie with Leap Motion) that will run with Unity 2020 (or newer) ?
I know these are 3 separate questions, but I'm not sure how to generate enough interest or response on forums to get an answer in my own life-time :o)
