Hi,

Possibly these could be very basic or silly questions.

I tried to execute "Rigid Body Toolkit Samples" online.(http://media.naturalpoint.com/software/ ... Sample.zip)

But it didn't work properly. So I tried "Point Cloud Non-COM C++ Sample" online, and it worked. (http://media.naturalpoint.com/software/ ... Sample.zip)

And I have no problems in using "Rigid Body Tool" provided originally.


Belows are the problems I have experienced. (I'm using Visual Studio 2005 Express Edition in Windows Vista.)

1. In the debug mode, RB_LoadDefinition() always fails. But it works when I just execute the .exe outside the Visual Studio. In case of the "Point Cloud Non-COM C++ Sample", it also didn't work properly in the debug mode and worked in the execution of the .exe.

2. RB_LoadProfile() doesn't seem to work properly or there are some bugs in treating error message because it says "success" even when I use a invalid filename.

3. RB_StartCameras() says "success", but I'm not sure because the next function RB_GetLatestFrame() fails. According to the error message, it says "invalid license". So I checked RB_CameraCount(), and the camera count was 0. (But there was no license problem and camera starting problem in case of the "Point Cloud Non-COM C++ Sample".)


#3 is the biggest problem.
I compiled both "Rigid Body Toolkit Samples" and "Point Cloud Non-COM C++ Sample" in the "samples" subfolder. But one works and the other doesn't work properly. Do I need to check something I might have missed?


Thank you,

As to #3, I have exactly the same problem. I e-mailed back and forth with the NaturalPoint people; they sent me a new license file that I just tested, but it didn't help. Now I'm waiting for them to wake up on the other side of the big pond and reply

I hadn't looked at the output of RB_CameraCount() yet, but I just did and get 0 just as you do.

I checked with CreateFile() that the files I load with RB_LoadProfile() and RB_LoadDefinition() exist; they do.

Edit: I can reproduce #2 as well. Just throw a nonexisting file name at RB_LoadProfile() and it still returns success.

Hey guys, thanks for the additional info. I know we've been working on this prior to today without success. Lets see if we can get this resolved today. I will follow-up with you guys via email. Hopefully with some fixes.

Okay.
Let me know and get the changes if somethings are fixed.

Thanks,

For other people that might be having the same issue, this problem was resolved by installing the latest OptiTrack SDK and latest Tracking Toolkit.
