test_opengl crashes while loading ptable's

[gaborpapp]

in OSX 10.9.5.

error in console:

[OpenGLDepthPacketProcessor::loadP0TablesFromFiles] Loading p0table 0 from './../p00.bin' failed!

The files don't exists. Are they removed or should be generated somehow?

"test_opengl currently broken, because you need the p0tables and raw ir data as binary files. We need to add a tool to dump these files from the device" from #31 (comment)

[gaborpapp]

managed to dump the ptables from CpuDepthPacketProcessor like this: gaborpapp@3e700c4

[gaborpapp]

added raw ir dump to the ptables export. https://github.com/gaborpapp/libfreenect2/tree/dump-rawir
together with #111, test_opengl seems to work fine on osx.

Could you submit a pull request and close the issue here?

[gaborpapp]

Ok, but the current solution is quite a bit of a hack. You run protonect and it dumps the data. What would be an acceptable solution? Should protonect dump the data on a command line switch? Or a separate application for this?

[floe]

I think a commandline switch (maybe "--dump") would be the best solution. As far as I can see, your implementation already has a boolean flag for dumping the ptables, so you could just set that from the cmdline?
