NP enumerations in c#

Post by leith » Fri Nov 16, 2007 4:01 pm

btw, I've noticed that the enumerations referenced in the documentation are not making their way through COM and through the .net COM interop as far as I can tell... unless you folks can point me to where they import to. I've imported lots of COM libraries through COM interop before, and they usually do show up as enumerations. In the meantime, I've just been looking at the c++ header files you folks provide in the include directory of the SDK, to get the actual integer values. Passing them works fine for now.

Hey Brad,

You'll have to manually #define the values you need for SetOption in your managed code. We don't have any managed #defines you can include currently. If there is anything else that you're not able to get access to, let us know.

I have ported the most used enums and constants to C# from the OptiTrack headers. Haven't made everything into nice names, but a bit of manual work or a clever regex should do the trick. Hope this is useful to you (or someone)!

Code: Select all

    enum NPHWModel
    {
        Oldtrackir = 0x100800a8,
        Smartnav = Oldtrackir + 1,
        Trackir = Smartnav + 1,
        Optitrack = Trackir + 1,
        Unknown = Optitrack + 1
    }

    enum NPHWRevision
    {
        OldtrackirLegacy = 0x200800b8,
        OldtrackirBasic = OldtrackirLegacy + 1,
        OldtrackirEg = OldtrackirBasic + 1,
        OldtrackirAt = OldtrackirEg + 1,
        OldtrackirGx = OldtrackirAt + 1,
        OldtrackirMac = OldtrackirGx + 1,
        SmartnavBasic = OldtrackirMac + 1,
        SmartnavEg = SmartnavBasic + 1,
        SmartnavAt = SmartnavEg + 1,
        SmartnavMacBasic = SmartnavAt + 1,
        SmartnavMacAt = SmartnavMacBasic + 1,
        TrackirBasic = SmartnavMacAt + 1,
        TrackirPro = TrackirBasic + 1,
        OptitrackBasic = TrackirPro + 1,
        OptitrackFlex = OptitrackBasic + 1,
        Unknown = OptitrackFlex + 1
    }

    enum NPLed
    {
        One = 0,
        Two = One + 1,
        Three = Two + 1,
        Four = Three + 1
    }

    enum NPOption // TODO: fix casing on all items
    {
        StatusGreenOnTracking = 0,
        TrackedObjectColor = StatusGreenOnTracking + 1,
        UntrackedObjectsColor = TrackedObjectColor + 1,
        ObjectColorOption = UntrackedObjectsColor + 1,
        DrawScale = ObjectColorOption + 1,
        Threshold = DrawScale + 1,
        ObjectMassWeight = Threshold + 1,
        ObjectRatioWeight = ObjectMassWeight + 1,

Thanks, that's awesome.

I also noticed that you can extract the #defines from the c++ header files and pretty much copy and paste. the syntax for most of them is compatible. Looks like you might have done that for a lot of it already though.

Yeah, C# coding standards are different than C++, so I made a start on decapitalizing the names. I wrapped everything into C# enums, but unfortunately, that means you have to typecast the enum to an int before you pass it to a function from the OptiTrack API...

I have posted some code in this thread recently.

the later code works better than the earlier code.

I tried that too for the NP_OPTION enum, thanks for your wider range of enums!
