Thanks Hans. I know the example patch already and I have [pix_rtx] working fine inasfar as I can get it to do what the example patch already shows. I think my question is more about data flow and Gem. My patch and [pix_rtx} are just an example of a more basic misunderstanding I believe I have which has not been cleared up despite many hours of work in Gem.<br>
<br>Could somebody explain to me my [pix_rtx] in my example patch appears to be processed before the rotation instead of after?<br><br>-John<br><br><div class="gmail_quote">On Tue, Mar 24, 2009 at 9:33 PM, Hans-Christoph Steiner <span dir="ltr"><<a href="mailto:hans@eds.org">hans@eds.org</a>></span> wrote:<br>

I think this is an appropriate place to discuss gem. In the Help browser, check out:<br>
<br>
examples -> Gem -> 04.video -> 04.videoRTX.pd<br>
<br>
I had to do some trickery to get it working OK. Check the archives for details, I remember some discussion about all the separators.<br>

Attached is a small example patch of how I just don't get Gem...still...<br>
<br>
[pix_rtx] has a steady wave that normally flows from left to right.<br>
<br>
I would have thought that the attached patch shows me rotating the image first, then applying [pix_rtx]. So it would stand to reason in my mind I would see a rotated image with [pix_rtx] flowing from left to right.<br>
<br>
But that isn't the result I see. The patch has [pix_rtx] flowing from right to left now. It is as if [pix_rtx] is applied *before* the rotation instead of *after* as I would have expected.<br>
<br>
Grasping at straws, I have tried [pix_separator] between just about every object, but that makes no difference.<br>
<br>
What am I misunderstanding that makes the behavior of the patch make sense? And...how would I get [pix_rtx] to flow from left to right on a mirrored image?<br>

P.S. Are questions like this better on the Gem-dev list? That's a developer list but at the same time I feel a bit awkward putting too many Gem questions on a Pd list<br>
