[PD] [VBAP] multiple sound sources
Hi, I'm writing a spatialisation patch for 3 or 4 sound sources. I didn't found the way to control them with a unique vbap object, as ambiencode does... I think it's not possible, but I ask just to be sure. thank you r ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] git repositories for all of pure-data/trunk?
Hi, I notice git repositories exist for the Pd and Pd-extended sources, but not for externals, abstractions or any of the other stuff currently in pure-data/trunk. Has there been any discussion about switching all of this over to git? Jamie ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] flip image in glsl
Le 10/04/2013 07:48, Patrice Colet a écrit :
Hi Jack,
the fragment code is now very short and much more elegant, certainly faster
than using conditions, I guess this is due to [pix_info] that is computing
dimensions of the resulting texture.
This procedure seems to work for horizontal flipping then corrects strange
behavior between pix_image and glsl,
but vertical flipping has no consequence.
It's also possible to crop using the dimen parameter, but I believe there is
a zoom parameter missing to do it entirely.
So I'm going to restart coding a fragment code from the basis you propose
that would allow to crop both textures, because this looks fundamental for my
possible use of this object, that is mainly about mixing two textures which
coordinates could be modulated to fit a particular context, where textures
would need to be placed accurately without having to modify it in an image
editor, maybe you have an idea about how to do it simply?
You can do operations directly on vec2 instead of two floats in your
fragment shader.
You can also avoid condition (could be slow).
See patch and glsl vertex and fragment attached for flip.

Hello Patrice,
Not sure to understand what you mean about the problem on
horizontal/vertical flipping.
Here a new patch and the fragment shader. This time, all is computed
from the Gem window size.
You can flip, scale and move each texture. (the flip is done from the
center position of the Gemwin).
In this patch, i use a workaround to avoid to see the 'border' of the
texture thanks to the message [perspec( on [gemframebuffer]. I don't
know if there is a better solution ?
Hope it will help.
++
Jack
PS : I can clean the this patch and keep only the part about position
and scale of a texture with GLSL for Gem example if it is interesting ?
