Re: "Unable to stream frame" (any protocol)

<t>I guess my initial post was not clear enough...<br/> <br/> The VRPN client version can not be the problem, because the error occurs even when no clients are connected. Also, the TrackD and NatNet protocols suffer from the same problem.<br/> <br/> As soon as I've completed my new camera setup I'll...

Feature suggestion: allow mirroring

<t>In tight spaces, it can be useful to view the scene via a mirror, so that you can place the mirror image of the camera farther away, beyond the wall of the room. Unfortunately this will also result in a mirrored camera image, confusing the calibration and tracking. (Unless all cameras work via a ...

Re: Sharing views when calibrating

Yes, alas, currently there must be a volume that can be seen by all cameras.

The ability to have non-overlapping camera volumes is, I think, one of the most often requested features on this forum :)

NatNetLib.dll not found

<t>Problem: Versions 1.1.034 Final C and D of the Rigid Body toolkit seem to be missing a DLL file called NatNetLib.dll. The library NPRigidBody.dll depends on NatNetLib.dll since Final C, causing applications built against NPRigidBody.dll to break. Finals B and A work just fine.<br/> <br/> Suggeste...

"Unable to stream frame" (any protocol)

Weirdness... when I check the box "Broadcast frame data" under VRPN Streaming Engine in the Rigid Body Tool, it acts as usual, but my VRPN client cannot connect. Also, when I minimize the Rigid Body Tool, an error dialog pops up titled "VPRN [sic] streaming engine" with the message "Unable to stream...

Re: VRPN version?

I'm using VRPN 0.7.15 (latest version), get the warning, ignore it, and have no problems at all with it.

Re: Aligning Optitrack data with a Java3d model

I don't know Java3D, but if it is anything like a normal 3D API, you can correct for left-/right-handed coordinate issues by multiplying the entire thing with a scaling matrix that mirrors one of the axes, e.g.: 1 0 0 0 0 1 0 0 0 0 -1 0 0 0 0 1 (OpenGL equivalent: glScaled(1, 1, -1)) Hope this helps.

Re: Device driver problem

Annoying, isn't it? You'd think Windows would figure out "oh, same device, let's use the same driver" but noooo... and when you plug them into another USB port you'll have to install the drivers all over again as well. Stupid Windows.

Re: VC++ GetFrame returns NULL

Just for the record: what you mean is of course "if(pFrame==NULL){Sleep(1);continue;}" or the Sleep will still not get executed.
