NatNet Bitstream

[carbnet]

hallo guys, i'm using the V200:R2 cameras for my Project. In Arena i broadcast the object pose and want to receive it in ROS. I want to use the NatNet protocal. but since there is only 1.4.0 version of the Bitstream Syntax available online, is it possible to get the updated version of the Bitstream Syntax.

thanks.

i have build two rigid bodies in Arena and want to track them in two different machine. the other one runs linux. i try to unpack the data frame packet according to the NatNet Bitstream Syntax of version 1.4.0. i tried to read the position and the quatenion of the two rigid bodies in linux. but i can only get the first defined rigid body although i broadcast two. the ID of the first defined rigid body is always the same, but the second changes all the time. And the programme shows as if the second rigid object doesn't exist although i can read the position of the markers from the second object and i can read the number of the object are two.
so i want to ask has the Definition of the Dataframe packet been changed from the Arena with the NarNet version 1.4.0.
by the way i use the Arena 1.7.2 and if does so can the updated version be posted here?

Hello -

The packet client sample in the distribution of NatNet should have all of the relevant information for decoding the packets.

As for the multiple rigid body issue, does Arena properly track both rigid bodies when you are attempting to stream them?

the tracking of the both rigid bodies in Arena worked perfectly. i have another question: which version of NatNet does the Arena support? 2.2 or the older, because the Frame of the MocapData packet seems to have been changed.

Arena 1.7.2 uses the latest version of NatNet, found here.
