Objet: Re: [PD] flip image in glsl
hello,
when using rectangular texturing, coordinate goes from 0 to image
pixel size.
when using rectangle 0 mode, pixel coordinate goes from 0 to 1.
(sometimes 1 is for the power of 2 bigger than the image pixel
size)
so, in rectangular mode, use pixetl_size - image coordinate to flip
the image.
and 1 - image coordinate in non rectangle mode.
Image can be fliped because the fliped flag is not used on the
shader.

Hello,
how is it possible to flip upside down an image in glsl example
05.multitexture
I tried to implement this in fragment program:
http://stackoverflow.com/questions/9857089/flip-upside-down-vertex-shader-gles
but it doesn't work. The only thing I can do is changing texture
scale and position, but I couldn't do it with negative values
like it would be done in pix_coordinates.
In fact when I use pix_multiimage before pix_texture, the image
gets flipped, I don't know why...

Hello Patrice,
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.

[PD] best way to play (long) 24-channel wav file in pd
Hello list, I want to play a 24-channel wav file in pd. It is rather big (several minutes), such that pre-loading the data into tables will probably not work (have to check that though). I tried zexy/sfplay but it seems to be limited to 8 channels. In the final application, we want to use a set of 48 FIR filters (each 512 taps long) to downmix the 24 channels to 2 outputs.

Re: [PD] Preferences Dialog
Under osx, this is usually what is done, there is no apply button. Hans's proposition to have separate message is very good as well. It is much better to change from the patch, for example, only the number of audio outputs than to overwrite all parameters. One thing missing as well is the ability to select audio/midi device by name from the patch, instead of numbers. This is specially important for installation when you have different devices connected and no way to be sure of the order... One preference menu seems very nice to me. Audio / midi / startup / path tabs for examples. In osx, the preferences menu should not be under the Edit menu but under the main app name, just after About Good luck, Best, n Le 08/04/13 03:29, Hans-Christoph Steiner a écrit : I think this makes a lot of sense. Making the preferences take effect immediately is how most platforms are going these days, and is really how Pd itself responds. So I think Pd's preferences should behave accordingly. The problem is that it will be tricky to do with the current message format. I think you should probably just ignore the existing preferences mega-messages and make one-message-per-preference. That would also make it easier to set the preferences from a patch. .hc On 04/05/2013 01:19 PM, Jonathan Wilkes wrote: Hi List, I'm going to start coding up a single preferences dialog to replace the disparate settings dialogs that live in non-standard menus of Pd.

When a button is clicked it will bring up the tab in the dialog window for those particular settings. (This turns out to be surprisingly easy to do in Tk.) So far I think there should be an Audio button, MIDI button, and maybe a GUI button that could be be split out later if needed.

Re: [PD] Control a USB fan from Pd
Well, Any usb fan really. for example, this one: http://www.newegg.com/Product/Product.aspx?Item=9SIA1HE0GD0017 There seem to be several pieces of software for controlling usb fan speeds to control temperature/noise out there, but I'm not familiar with all of them and their potentialities. Most of them are not for usb control and I'm interested in continuous control, which most don't seem to have. I'd rather avoid the soldering route if possible, so I was just wondering if people have had experience controlling the voltage output of a usb port.

Re: [PD] flip image in glsl
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. ++ Jack ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
