[PD] Multiblob and Animations...
Hi List I've been working with pix_multiblob to affect layers in 3D. I'm managing to get an erratic signal from it, which from my point of view, represents great success! ; ) However, there are few areas I am still confused about. First of all, I am unsure of how to extract muliple co-ordinates from [pix_multiblob]. I understand that the data from multiblob is collated within a matrix. I am able to see this in the pd window when I print. However, I am unsure how to use a matrix. Is there a certain object that I should be sending to from [pix_multiblob]? And in turn, how would I convert the matrix into xy co-ordinates. In the archives I found a response to similar a question saying there was a gem example with matrix and multiblob, but I can not seem to find it. Any idea what and where this is? Also... I am trying to use the various xy co-ordinates to trigger animations. However, I am unsure of how to animate with Pd. I noticed that [splinepath] does something similar to what I am looking for. This seems to be based on array's. However, looking at the help data for array's has not made it any clearer. Is there a way of inputting a list of co-ordinates that act as a path for an image to follow? Hope thats not too many questions. And is it easier for the list if I divide questions up (for archive purposes perhaps)?

And in turn, how would I convert the matrix into xy co-ordinates. there is a separate library dedicated to the kind of matrices output by [pix_multiblob]; it's called iemmatrix. however, you should have an understanding of matrices in order to use it. matrices of this form are simple messages which you can treat like any other message. attached are two examples on how to extract the rows of a matrix (and pix_multiblob will give you one row per blob; so this is interesting data), one using iemmatrix ([pix_rows]) and one using zexy ([pix_rowz]). it is left as an exercise for the user to make a pd-vanilla implementation. just send the mtx-output of [pix_multiblob] to the object, and you will get nice lists for each blob, starting with the index of the blob (zero-based) and then comes the data. use [route] to filter the relevant blobs and [unpack] to access the data. In the archives I found a response to similar a question saying there was a gem example with matrix and multiblob, but I can not seem to find it.

Re: [PD] complex network
On Fri, 3 Apr 2009, Frank Barknecht wrote: The last paragraph explains sparse matrices or rather, why you often don't need to treat them specially in Lua. Well, you better treat them specially in Lua, else you'd implement a nonspecial matrix product using three for-loops as usual, and then the result of two sparse matrices will be a nonsparse matrix. What do you do with that? No, you need to treat them specially, because assigning a bunch of zeroes in a lua table will take RAM. Furthermore, I just tried Lua, and you do need to treat every nil value specially, because you can't perform arithmetic on nil (which is quite normal). This is fixed by defining a method for the __index selector (using [] sends a __index message to the table). And then their triangle matrix gimmick... the very fact that those tables are actually hashtables instead of anything like pd float tables, make them take usually twice RAM or more (perhaps 3 or 4 depending on their implementation) if you just use all slots, so if you only use half of the slots then you're not saving any RAM at all compared to pd's float tables. That page is not outright lying, but it's definitely not telling the truth. Hashtables of pairs are one way to represent sparse matrices, but if you ever need to lookup complete rows or columns, then you need a hashtable of hashtables for rows, columns, or both (twice the same data transposed). Depending on how sparse the nonzero data is supposed to be and how clustered the nonzero data is supposed to be and how you need to be accessing/transforming the data, some other representations may be more attractive than the hash or the hash-of-hashes. For example: * matrix-of-matrix: a 400x400 matrix could be cut into 20x20 pieces put into a 20x20 matrix and so every 20x20 piece that is completely filled with 0 is not allocated and instead replaced by a nil or zero. You can tune the size of the pieces depending on what goes well with the data set. * quadtree: make a 2x2 matrix of 2x2 matrices of 2x2 matrices of 2x2 matrices of 2x2 matrices of 2x2 matrices of ... and just don't allocate any piece that only contains zeroes. Here I suppose that this is using ordinary arrays as you can find in Python, Ruby, C/C++, Tcl, etc., and apparently not Lua (?). But you could do quite similar things with Lua anyway. In any case, each of those representations needs algorithms customised for them, unless you can figure out a generic design that is efficient with several representations, perhaps using a foreachnonzero loop operation as the central concept. _ _ __ ___ _ _ _ ... | Mathieu Bouchard - tél:+1.514.383.3801, Montréal, Québec___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

There are still files in the svn repository that make it impossible for
me to update the Pd svn on a Windows box, since tortoise svn at least
abandons the update at the first error. (Files with * in the name.)
A previous attempt to solve this was the hexloader, I think it failed
because not many people can recall the hex equivalent of characters like
'' in less time than it takes to do something else instead, like [expr].

Re: [PD] pdpedia
Yeah, I started with your stuff when I began doing this, and also found something from another source, but there was no author in the file, and that was a few months ago, so I don't remember who it was. I have added a few other tables, as it would be nice to be able to store multiple authors for anything, plus I wanted to break out a couple other things as well. This is a kind of side note, but one thing that would be really cool would be to modify the [pddplink] object, so that you can send pd messages to your patch, and this could be made to make calls into the database, as the links are selected, and because the interface is going to be dynamic, there are going to be a lot of files to open. One of the things that I have noticed about some of the pddp stuff is that it takes forever for a patch to find what it is looking for, along all the pd search paths it goes through, and having to wait 30 seconds for it to find what it is looking for is just not conducive to using it. The information should come back as fast as possible. That is one reason I am using a local database file on disk (or in memory), rather than using a database network connection (that is in the works right now). It would be nice that we could add an SQL file that anyone can download, and load up. I hate having to be forced to always have a connection to use something. I should make a request for a change to the PDDP people, and have them update the patch. I think it would be a really nice addition to allow one of those links to send 'pd' messages.

Perl uses gt,lt,ge,le,eq,ne as string comparisons whereas ,,=,=,==,!= are used for numeric comparisons. Perl needs both by design. You could reuse the same names.

Sure, but bash is written in c and it can call its functions whatever it likes because they are built into the program. (It will also try to interpret your file name if it isn't alphanumeric) Pd too has that freedom for its built-in functions but also has the ability to load a subset of all imaginable functions as externals. The limitation lies in the inability of the various operating systems to accept files named using arbitrary combinations of the available character set. All of the OSs that I know of can handle regular a-z type characters, so I suggest sticking to that range for the names of externals. That's all.
