Turn off display of control marker count

Hello,

When adjusting the display settings, is there a way to turn off the number that shows the control marker count for a body segment? It seems that none of the display options allow you to do that and it would look much better for a presentation display.

Thanks!

Re: Arena runtime error when streaming

Yes, there are 3 rigid bodies and they are constantly in the frame; in fact they are motionless for the most part (including when it crashes). We are doing some testing so they are not on a person at the moment.

Re: Arena runtime error when streaming

Mike,

Arena is not recording at the time, simply streaming (preview mode? I'm not sure what that is officially called).

The frame numbers are not consistent, but the times have all been over 6000 sec when this occurs.

Thanks!

Arena runtime error when streaming

<t>I am getting a runtime error when I leave Arena streaming for a length of time (usually more than an hour). I am sending the data to Matlab and letting Arena stream in the background to get the data. <br/> <br/> Is this a known issue or does anyone have any suggestions on how to go about solving ...

Re: Streaming Individual Markers

My sample code for streaming from Arena to MATLAB using Java. Not sure what place is best for this, so please feel free to move it if necessary. This also might work with Tracking Tools but is untested. %For accessing Arena's multicast stream using Java within MATLAB. Tested %with MATLAB R2009b. Obj...

Re: Streaming Individual Markers

<t>Morgan,<br/> <br/> I switched them myself after no luck with ByteOrder and it seems to work very well. I didn't know I could switch the integers, I thought it had to be the bits (maybe gives the same thing). <br/> <br/> Once I get through the code and can read in the data and process it I can pos...

Re: Streaming Individual Markers

<t>This java code does seem to work, however I get erroneous float values with very high exponents.<br/> <br/> Assuming the byte array for the X value of marker 1 is something like [A B C D] where these are values from -128 to 127, values C and D seem to stay constant from frame to frame while value...

Re: Streaming Individual Markers

<t>Morgan, <br/> <br/> Thanks for the help. I am writing the overall code in Matlab, I am just using java within matlab as a way of receiving the multicast data.<br/> <br/> As a specific reference, I am looking at the code here, from the depacketization example under the Unpack function:<br/> <br/> ...

Re: Streaming Individual Markers

<t>I am able to read in the packet sent by Arena, which is a series of 8-bit integers. <br/> <br/> I cannot tell from the C++ code example how to get the values for marker position, etc. Small values like the number of rigid bodies can be read directly but I don't understand how to get the floating ...

Re: Streaming Individual Markers

<t>I have had no luck transforming the C++ code from the Packet Client sample to Matlab using the udp() function or the simulink block 'udp receive'.<br/> <br/> I am attempting to use java within Matlab to receive the multicast sent from Arena. I have the data port set to 1511 which is what I am 'li...
