Hi,

I was planning on buying a TrackIR device, however upon searching for information on how difficult it is to use on my own programs, I found out that the SDK is not available at all except for commercial game development! Is this really the case or have I misunderstood something? It would seem pretty dumb to spend so much money on a device that I cannot truly use myself.

Hello:

We do offer an SDK for you to develop your own applications using the TrackIR hardware. You can download it here:

http://media.naturalpoint.com/software/ ... eta.03.exe

The TrackIR Enhanced Interface, which is what games use to communicate with our software is not freely available, you must sign an agreement to get it, and be developing a title.

Let us know if the OptiTrack SDK is what you had in mind, if not, I am sure we can find something to fit your needs.

What is the difference between the "TrackIR Enhanced Interface" and the optitrack SDK? Ie. is there something the enhanced interface can do that the optitrack SDK cannot? The SDK website says the TIR SDK "Provides scaling", what exactly does this mean?

Here is a short comparison of the two.

The TrackIR Enhanced SDK
- Provides access to 6DOF (X,Y,Z, Roll, Pitch, Yaw)
- Requires TrackIR software to be running
- Interfaces with a single camera
- API is available through a loadable DLL with C++ wrapper provided
- TrackIR software handles tracking, smoothing and adjustable scaling
- Requires a license agreement to be signed and faxed to us
(If you wish to use this SDK, please let us know and we will send a
copy of the agreement)

The OptiTrack SDK
- Provides access to 6DOF (X,Y,Z, Roll, Pitch, Yaw)
- Provides access to raw tracked marker locations
- Interfaces with multiple cameras
- API provides tracking, smoothing and 6DOF functions
(no scaling is provided though, would need to be written by user)
- API is available via a COM interface
- Does not require additional software to be run
- Downloadable free of charge from our website for review and use :
