[PD] live coding festival in newcastle, uk?
Hi all and happy new year, I'm looking into the possibility of running a live coding festival in Newcastle later this year. To be supported it would need to be a bit bigger than previous events dedicated to live coding - 100+ . It would include performances, talks and beginners workshops. So I'm gauging interest - if you would be interested in coming to such a thing, please add yourself on this wiki page: http://toplap.org/index.php/Newcastle2010 You don't have to sign up to anything - just click 'edit' and add your name to the list. You won't be committing to anything, but your interest would be helping make it happen! For those unfamiliar with live coding, there's a bit of info here: http://toplap.org/uk/about/ Thanks very much, alex -- http://yaxu.org/ ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] GEM/GLSL how to compute correct texture coordinates for non-power-of-two images
Hi,
The subject resembles very much that of one recent message of mine but
it is NOT the same.
I think it's better to start a new thread because the previous one was
erroneously focused on rectangle textures: I was suggested to use them
to solve a problem I mentioned, and though I do appreciate very much the
suggestion, it actually pointed me to the wrong direction.
So, I have learned that when you use an image as a texture (be it loaded
from file, generated by camera input or by a pixsnap), the texture
internally has power-of-two dimensions greater than or equal to the
actual dimensions of the image, the rest being padded with black or
something.
Then, I've seen that even if I use a shader, I usually don't have to
worry about that IF the [pix_image] (or [pix_video] or whatever) that
generates the image is in the same line (of left-inlet connections) as
the [pix_texture] and the [glsl_program].
That is, when in the shader I use gl_TexCoord[0].st to sample the
texture, I get the right coordinates.
So, the 01 simple texture patch in the example folder works fine with
non-power-of-two-sized images with no need to be changed, and without
using rectangular texture mode.
However, as the attached patch shows, this is no more true if I use a
uniform variable to tell the shader to use a given texture unit N, which
correspond to some [pix_texture] object which is connected to another
separate [gemhead] and which has been sent a [texunit N( message.
So what I understand is that [pix_image] (or any object that creates a
pix and translates it into a texture) takes care of it by doing some
kind of OpenGL magic so that the texture coordinates being passed to
the shader are OK with no need to take care of that in the shader code.
The aritmetical part of this magic is indeed as simple as computing a
scale factor of W/Nw for width and H/Nh for height, where W and H are
width and height, and Nw and Nh are the next power of two equal to or
greater than W and H respectively.
The question is, what's the best way (if there is any) to reproduce
the magic that the pix objects do, in order to pre-compute this scale
factor and have the shader receive correctly 'normalized' coordinates?
I mean, I can calculate the scaling factor and pass it through a uniform
variable to the shader, and have the shader use it to rescale the
coordinates. This will work fine, but it seems (to me) that [pix_image]
and other pix objects are able to do this kind of rescaling somehow
_before_ the shader gets in action, since you don't need to change the
shader code if such an object (which is generating the image) is present
in the chain.
I hope I have explained the question clearly.
The attached patch shows the problem quite well I think. I don't attach
the images to avoid flooding mailboxes; any non-power-of-two different
sized images with those names will do; by the way I have attached them
in a recent message of mine.
Compare the behaviour to that of example 01 of the GLSL example folder:
even with a non-pot-sized image, that example works fine.
Note that no rectangular textures are involved. Rectangular textures
won't help (indeed I think it gets more complicated): I have the same
problem because I need to tell the shader the actual size of the
texture it has to use.
Thanks a lot in advance
m.
P.S. though I can't promise it, it's almost sure that I will post and
share the final patches, for what it's worth; but I can't do it yet.

Re: [PD] gem/GLSL: how to compute correct coordinates for rectangular textures
Le dimanche 03 janvier 2010 à 21:17 +0100, Matteo Sisti Sette a écrit :
Hi,
I guess if I had a deep understanding of openGL I could find the answer,
but I am obviously looking for a shortcut (at the moment) to solve the
specific problem I'm facing which should be pretty simple.
In the attached patch I try to use a trivial shader to texture a
rectangle with an image; the uniform variable curtex tells the shader
which texture to use.
It works fine if all images have the same size; however, if the textures
have different sizes, no matter the value of curtex, the texture
coords that are computed are correct for the image loaded by the
[pix_image] that immediately follows the [glsl_program], but are not
correct for other images.
So the question is: how should I change the vertex and/or fragment
shader code (or the patch maybe) so that the texture coordinates are
computed according to the dimensions of the texture that is actually
sampled?
It is important to NOT assume that the textures come from [pix_image]
objects, or at least, that they are loaded from image files: actually,
in real life, textures may be the video input generated by a [pix_film]
or an image captured by a [pix_snap].
What about [pix_resize] after [pix_image] ?

I ask because I want to simplify that code and the message itself in pd-gui-rewrite 0.43. Its currently a very strange format, and it no longer needs to be. Here's the only working example that I know of: http://pure-data.svn.sourceforge.net/viewvc/pure-data/trunk/doc/additional/pd-msg/1..msg_and_patch/6.relocate_windows..pd?view=log The idea is to make the message like this: relocate WIDTHxHEIGHT+XLoc+YLoc Currently its like this: relocate WIDTHxHEIGHT+0+0 0x0+XLoc+YLoc .hc Hi Hans, Is there a reason the message can't simply be relocate WIDTH HEIGHT XLoc Yloc? Whether using pd-ext or vanilla, I've always thought it seems really awkward to cram the coordinates into one big symbol.. -Jonathan Hmm, that makes sense. I wonder if this should just have the same syntax as 'canvas', so: relocate x1 y1 x2 y2 Where x is the upper left corner, and y is the lower right corner. So I restored the old relocate message, and added a new message which the GUI now uses a new message 'whxy'. 'whxy' stands for Width/Height/X/Y. Width/Height is the size of the window, and (x,y) is where the upper-left corner is located: whxy width height xPosition yPosition whxy 450 300 0 22 I am now thinking that perhaps I should make it called 'setbounds' after the old internal function, and make it mirror that: canvas_setbounds(x, xpos, ypos, xpos + width, ypos + height); i.e. setbounds Xleft Ytop Xright Ybottom After a little discussion with Miller, this one seems to make the most sense, so this is what the pd-gui-rewrite uses now. http://pure-data.svn.sourceforge.net/viewvc/pure-data?view=revrevision=12883 That's great. I think setbounds is a much better name than relocate; it has a straightforward connection to the arguments (unlike relocate). Is there any way to have the iemgui messages pos and delta for canvases? For example, if I have a canvas with a bunch of subpatches that all have different sizes, but I want to move them all up to the top left-hand corner or the screen, pos 0 0 would be really handy. The first two values of 'setbounds' are the same as 'pos', they are the upper left corner. But you have to also set the lower right too. This message is not really meant to be used a lot externally. Its really a direct mapping of the data that Tk gives to the format that Pd saves in the .pd file. Plus 'setbounds' doesn't even take effect until you close and open the patch again. .hc Access to computers should be unlimited and total. - the hacker ethic ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
