Re: Motionbuilder plug-in

Hey guys,

This is also documented in the MB plugin User's Guide (html file) that installs with the plugin. If the documented procedure is not working for you let us know and we can investigate further.

MB2009 support should be avaiable soon as well.

Re: NaNet Streaming integration with OpenTracker

I'm afraid I'm not familiar with OpenTracker, but you should be able to use message id 4 to request a description of the data (message id 5). e.g. Socket s; Packet p; sendto(s, (char *)p, 4, NULL, (sockaddr*)&HostAddress, sizeof(HostAddress)); We typically recommend using the NatNet client instead o...

Re: Streaming Question

<t>Agreed - Will add this as a feature request for subsequent versions.<br/> <br/> Re the parsing issue, it sounds like a version compatibility issue. The benefit of using the NatNet SDK is it insulates client from syntax changes. You can lso use it to check version numbers.<br/> <br/> Give me a cha...

Re: Streaming Question

<t>This is trickier. <br/> <br/> The Tracking tools can stream using VRPN or NatNet. VRPN uses TCP/IP for connection, and UDP packets for data transfer. This would be easier to connect to directly from MatLab, but decoding VRPN packets is very complicated.<br/> <br/> The ideal solution would be eith...

Re: Streaming Question

Hi folks, I think the question is how do i connect to a NatNet stream directly, without using the NatNet SDK, so I'll try to answer that. NatNet data is delivered in UDP packets using IP Multicast. The multicast address (or group) is 244.0.0.1. To connect to the NatNet server app (e.g. TrackingTools...

Re: Realtime data and NatNet

<t>No buffering occurs within the networking layer itself.<br/> <br/> As a quick test you could run one of the sample clients, such as the SampleClient3D, alongside your application. This should confirm whether the buffering/lag is in your client app or the server app (RigidBody).<br/> <br/> Morgan<...

Re: Questions concerning the streaming data from Optitr

<t>Good questions. Here's a shot at them:<br/> <br/> 1) What is the exact meaning of a "MarkerSet"?<br/> <br/> A MarkerSet is a group of markers that have some relationship as defined by the application ( e.g. an actor, a prop, a rigid body).<br/> <br/> A MarkerSet has a name (e.g. "John") and a lis...

Re: can't get NatNet samples running

<t>There are a few common reasons clients fail to connect to Arena:<br/> <br/> - Streaming from Arena - If using the SampleClient3D , you will need to have a pt2 and a skeleton file loaded. I think the SampleClient app is looking for id'ed markers, so it won't show markers from just pt2. I dont thin...
