Anyone know if you can use the OpenGL GLX extension with GEM?

I am a complete and utter noob when it comes to OpenGL, but it seems like this would make it possible to send gemlist data over a UDP network connection. My initial tests seem to indicate that GEM does not support GLX: I tried GLX objects like [GEMglXCreateContext] but they didn't create.

I'm ultimately looking for a way to stream from GEM to a remote computer over the internet, without using the processor intensive [gem2pdp] object and [pdp_theonice~]. Alternatives to GLX or PDP are very welcome too.

hi pd123!
i didnt think this was possible, but after some research im not so sure anymore.
i got this interesting dokument
OpenGL Graphics with the X Window System (pdf)
at the bottom of this page
http://en.wikipedia.org/wiki/GLX

one thing i didnt get:
do you want to send the rendered data as a video live stream or just the rendering instructions, so the image has to be rendered on the 2nd machine?

i just wonder about how practical it would be to take data from the gfx card, load it in the cpu, compress, send through network, load it again in the cpu, uncompress, and finally on the other gfx card to output on the other machine. i experienced that with resolume ages ago, wich provides this feature to send videostreams over network...and it really sucked. even wit 320x240!
or are you talking about a setup, where all maps exist on every machine? could you explain what exactly you want to share over network? maybee there is a simpler solution. like an analog framegrabber.

Hello sonsofsol,

Thanks for responding! Really I was asking about two different things: streaming video and sending render instructions. Streaming video, like with [pdp_theonice~], is the more desireable of the two.

From your analysis it seems that sending render data is probably not practical, though it may be possible.

I don't know what this means, but if you mean like how netpd handles GEM then no (identical patches on multiple machines, control messages are sent remotely).

Do you mean a hardware device that would then be routed back into a capture card?

Also.. does [gem2pdp] still work? I can't seem to get it to function.

-- if you mean like how netpd handles GEM then no
this is what i meant

--Do you mean a hardware device that would then be routed back into a capture card?
YES. AV out -> capure card

Ok, so with [gem2pdp] not working, the only way to send GEM visuals as streaming video is to use hardware.

I think, unfortunately, that this is correct.

This is a real shame as it makes it impossible to just rent a VPS and create a live, generative video on the web.

do you have to feed the strem back into gem? if not, maybee an external screencapture program with streaming ability exists that could fit your needs? something like teamviewer?
