Camera control in Point Cloud
Hi. It is possible to control the minimum size of the items detected by the cameras in PointCloud using the API of the OptiTrack. Can I use a code like this in order to control the size of the items, for example? CoInitialize(NULL); CComPtr<INPPointCloud> pointCloud; CComPtr<INPCameraCollection> spC...

Point Cloud Calibration Tool hangs
<t>Hello,<br/> <br/> I run the Point Cloud Calibration Tool many times and it sometimes hangs in the Wand and Result. It happens when suddenly appear many marks on the capturing volume.

GetOption NP_OPTION_FRAME_RATE
Hi. I have several OptiTrack cameras model C:120. I need to obtain the Frame Rate that currently has the camera. In order to obtain this value, I use the function GetOption with the parameter NP_OPTION_FRAME_RATE. The result of the function GetOption is NP_E_DEVICE_NOT_SUPPORTED instead of S_OK. CCo...

Re: Grayscale image capture
Hi.
I have change the option NP_OPTION_FRAME_RATE using a value of 50 (50%) and the sample works fine.
Thanks a lot.
Yes, I was wrong. The option is NP_OPTION_FRAME_DECIMATION.Regarding NP_OPTION_NUMERIC_DISPLAY_ON, do you mean NP_OPTION_FRAME_DECIMATION?
I have change the option NP_OPTION_FRAME_RATE using a value of 50 (50%) and the sample works fine.
Thanks a lot.

Hi. I have the following problem: I had modified the pointcloud example adding the following lines of code: LONG lNumCamerasDetected; result = pointCloud->get_CameraCount(&lNumCamerasDetected); after the call: pointCloud.CoCreateInstance(_uuidof(NPPointCloud)); Also I have put the call to the fu...

CoInitializeEx Multithreaded
Hi. I am developing a DLL to handle Optitrack camera model flex c:120. Due to the use of other libraries, I am forced to initialize the COM objects using CoInitializeEx(NULL, COINIT_MULTITHREADED); instead of CoInitialize(NULL); This causes a memory exception when calling the GetFrameImage function ...
