Hi IOhannes<br>
<br>
Fortunately, Syphon does not leverage QTKit (Quicktime = rather evil, and QTKit is a strange beast), it leverages IOSurface (and, IOSurface + IOHannes makes a rather nice pair, no?) <br>
<br>
I have taken a look at the GEM sources last night (from <a href="https://pd-gem.svn.sourceforge.net/svnroot/pd-gem">https://pd-gem.svn.sourceforge.net/svnroot/pd-gem</a> ) and have begun some very rudimentary work on a syphon.pd_darwin object.<br>
<br>
Is there a mailing list or resource I could leverage to ask specific GEM / XCode development questions, or is this list appropriate? I have some GEM internals (the state manager, inlet types and how active texture unit / binding works in an object, what GEM
base class seems most appropriate, etc) questions, as well as more basic PD external questions.<br>
<br>
I suspect it would take a more seasoned GEM developer only a few minutes to implement a syphon object for GEM, as it really is only a few lines of code.<br>
<br>
<a href="http://syphon.v002.info/FrameworkDocumentation/">http://syphon.v002.info/FrameworkDocumentation/</a><br>
<br>
Basically, a SyphonServer object is alloc/initted with a name and a context<br>
<br>
You then publish a texture via its glUint texture ID, and specify a region of interest, as well as texture target. Thats it, Syphon handles all IPC, notification and <br>
<br>
My reasoning for having someone close to GEM and who does active development be responsible for the syphon / GEM implementation, only to help fix subtle bugs that may arise, and have someone who is active in the community do it. Its also a load off our (Tom
and I) shoulders, as we have been doing almost all of the various plugins ourselves (Unity, Jitter, OpenFrameworks, FFGL, Quartz Composer, and much of the Java/JNI stuff).<br>
<br>
That said, im happy to get some basics working and have the community step up :)<br>
<br>
Thanks.<br>

<br>
ah good to know.<br>
<br>
sorry for spreading false myths, but i was sure that at one time i read<br>
something about using a technology Gem was not using (probably QTKit)<br>
and i mistook that from meaning "64bit only".<br>
i did not check back on the homepage before making my claims.<br>
<br>
well, this means that time is the only obstacle for getting syphon<br>
support into Gem...cool!<br>
