hi,
would really like to work with the new Syphon client within Field. but
what exactly does it mean: "Syphon servers appear as texture maps in
Field's renderer "?
how is it possible to address the GLContext of a Syphon server? Can
you please give an example?

Anything served up by a syphon server can appear to Field as if it was
a texture map, and enters the graphics system as such. The texture map
just happens to be updated automatically with the material "sent" from
the server.

Essentially OS X built in magic lets you share a (set of) GL texture /
FBO names between processes. So no data (other than an int or two) is
actually being sent anywhere, once the server has it's data on the
graphics card, any client can use that data on the graphics card for
free.

As usual, my documentation lags behind the code. For now, a test
syphon server (from their example code) and a demo sheet are attached.
Any trouble let me know,
Marc.
