setting mask rectangles

<t>Is there any magic to adding blocking rectangles via the OT SDK? I'm doing something very simple. Taking the center of the objects in the current frame, and then calling the Camera.AddBlockingRectangle method, subtracting and adding 10 to the center values to make a 20x20 rectangle centered on th...

bug? Get Option Video Type

potential bug in the OT SDK:

calling GetOption with NP_OPTION_VIDEO_TYPE, seems to return 0(PC) even if it has been set to 2(Cam). The cam is verified to be working in mode 2 by looking at the drawn frames.

Re: New ARENA software 1.3.035 beta available

<t>residual is up to about 1.5 - 2 cm. But its worth noting that my cameras are close around my volume. Closer than you'd have them if the lenses were longer. Which is the intent. More compact volume. Not larger volume.<br/> <br/> The calib values are more around .2. Some are sub .1.<br/> <br/> The ...

Re: New ARENA software 1.3.035 beta available

<t>impressions:<br/> <br/> in camera masking is unclear. Can't tell if its working or not. Does it replace the existing masking or is there a specific way to turn it on?<br/> <br/> I now have all 8 cameras using 60 degree fov lenses. The calibration is running quite smoothly and the calib does seem ...

Re: Clarification on skeleton support

<t>sorry to barge in. related question out of curiosity:<br/> <br/> Does poser retarget BVH data on import or does it require that BVH data already be in the correct proportions for a character?<br/> <br/> Also, when you describe the movement as "jittery" do you mean noisy all over? Or is it more li...

Re: GetObjectData

okay, this one is officially driving me nuts. I've tried allocating a byte array and passing it through that ref a number of ways and none of them appear to be working. my latest: public static int DoFrameDump(INPCameraFrame camFrame) { int ret = 0; unsafe { byte* secbuff = stackalloc byte[4096]; re...

Re: Manual Labeling of Data - Arena

<t>Birch, this has actually been a big concern of mine for some time as well. Trajectorization strips out point cloud data that's unlabeled. But that data could very easily be cleaned up externally if it would just survive the trajectorization and make its way out of the system via the c3d file expo...

Re: Sincronization

<t>its not automatic but it could work for a limited setup:<br/> <br/> marker up a rigid body and at the head of the take, drop it onto the force place. You'll see the impact in both arena and on the force plate data, and that will allow you to sync a take when you merge the data after the fact.<br/...
