Hi Cyrille,
Thanks you very much! I tested it and it works for me. However I think
geometries other than 3 1 do not work yet as they should. 2 2 gives strange
results.
what do you mean?
it look like it should imo.
maybe there is a bug so it did not look the same here or on your computer, or
we may did not have the same expectation.
I added some things to the interface, basically exposing some features of
gemwin such as offset or border, or frames per second, they can all be set
through one inlet, am not sure if the message names I created follow GEM
convention I wonder if for a complete functionallity all gemwin methods should
be made acessible to the user. Let me know if you find usefull, what I added
well, i'm usually not a big fan of gui.
maybe it jus miss an inlet connected to the gemwin ...
Cyrille
Again thank you very much!

hello cyrille,
the glsl_fragment does not like the new shader if I bang it I get:
compile info log:
ERROR: 0:43: '!=' wrong operand types
ERROR: 0:45: '!=' wrong operand types
ERROR: 0:57: '!=' wrong operand types
ERROR: 0:59: '!=' wrong operand types
there is a type problem between float and constant int
so it says shader not loaded,
Cheers,
Florian

hello,
it look like a bug in the original shader.
thanks for reporting it.
this shader should work.
could you test it so that i commit it if it's ok.
BTW, the fade control is for both right and left.
so it can be twice what the user expect.
i.e if you want 10 pixel shade on the right, so 10 pixel shade also on
the left, you have to set overlap to 20.
maybe i should change that.
feedback welcome.
Cheers

Here I could reproduce the problem with the example patch, having it
extended over the tripple head projectors.
I basically see the shading again only if I drive the overlap to
extremely many pixels.
I was wondering if this might have something to do with the texturing
mode rectangle anywhere?
I modified the the [flat_projection] so that I could define an offset
for the windowcreation.
Thanks for any help,
Best,
Florian

hello,
would it be possible to see your patch?
that would be easier to help.

Hello Jack,
01.flat_projection-help.pd seems to work.
I see either as 4 by 1 or 2 by the fractal image with decreasing
intensity at the edges giving a fade into black.
I looked into the guts of [flat_projection]
and if I send the print message to the glsl_fragemnet and the
glsl_program I get lots of info about user variable uvar#1 to uvar#4
I'm usin PD extended 0.42.5
I compiled GEM from the sources 0.93.3 (added some handmade classes)
My GPU NVIDIA GeForce 7300 GT
My screen size is 1280 * 1024
geometry is x 3 y 1
I would like to have an overlap of about 10 - 15 pixels
In my installation I see that I get a fade into black only if I
increase the overlap to very high numbers up to have the size of
my x
dimension. So I conclude the fade into black is just too weak.
How could I change that?
Thanks,
Florian
So I think the GPU model is ok

Dear List,
I'm currently working on a horizontal 3 screen projection (tripple
head) and I'm using the multiscreen projection flat projection
abstraction from Cyrille.
The overlap is working nicely but I don't get the it to fade.
i.e. I
see a vertical stripe of overlap with higher intensity.
Any help or pointer where to look for solutions very much
appreciated.
Cheers,
Florian
Hello Florian,
Can you tell us your configuration (Pd, Gem, GPU model) ?
Have you a problem with the example 01.flat_projection-help.pd' ?
