Re: [PD] [SPAM?] [LOW] fixing distortion on surface
We used one approach for SPIN: http://www.timesup.org/spin where we did render to texture of the image we wanted to be seen, then placed this texture on a model of the screen and filmed it from a camera placed where the projector was. in 2000, when we did this, it was only possible to do this sort of thing on consumer grade PCs using DirectX, so we had to go down that path. I think this is now doable in general OpenGL stuff, but no idea how. The latest version of software for SPIN was made in , so it would be probably relatively easy to modify their code for some other surface. I make it sound a bit trivial, but it isn't quite. But it is also a lot easier than it was originally for us.

Hallo, Matteo Sisti Sette hat gesagt: // Matteo Sisti Sette wrote: Frank Barknecht wrote: 4. Simply using a vline~ object and ?loop it? with a different start position the second time onwards. I'd simply do 4). That's ok if you're not gonna change the pitch while playing the sample. Yes, my suggestion is for a one-shot sampler with a looping end and constant pitch. Suppose for a moment that you don't need a sample start point different from the loop start point, i.e. the begin and end point don't change from the first to the second time. The phasor solution (which is trivial in this case) allows you to have a signal as an input to the phasor, thus allowing to change the pitch of the sampler in real time and smoothly. This is not possible (afaics) with the vline~ solution. For one-shot sampler phasor~ is not good IMO because of the quantiztion of the phase-inlet. phasor~ samplers would be terrible for drum-samplers. Also because of the phasor~ quantization it's hard to start playing with vline~ and then switch to looping phasor, unless you do a crossfade. (But a crossfade would work.) One solution for reproducing a sample with a signal pitch input without using a phasor is: (input pitch ~) | [rpole 1] | [tabread4~] (sending a [clear( to the rpole when starting playing) Puh, wouldn't [rpole~ 1] maybe be dangerous? Anyway I don't see any advantage in rpole~ over phasor~. However, the only way I can think of in order to switch from this to the phasor (or to jump to a given point of the sample) at the correct time independently of pitch history, is to use a [threshold~]; but that wouldn't be accurate because it's block-quantized. Any other idea? Hey!!! I just had one. But I would like anybody to suggest a simpler or more elegant one. I may use 2 phasors (or an rpole and a phasor), both fed with the same pitch input. Let's suppose this is the sample: |-SS-LB-LE--| where: SS= sample start (where we want the sample to start playing the first time) LB= loop begin LE= loop end With appropriate calculations, the two phasors can be adjusted so that: 1) Phasor A reproduces the sample the first time from SS to LE in its first cycle. In subsequent cycles it would do the same but it will be muted so we don't mind. 2) Phasor B reproduces the loop region; its initial phase is calculated in such a way that at the beginning, when it is muted, it will be producing garbage, but when phasor A will reach point LB for the first time, phasor B will also be on LB, so that, during ONE cycle of phasor B, the two phasors will be reproducing *exactly* the same portion LB-LE synchronously. Show us the code! ;) This may work, but indeed would be very complicated. Also I assume, that changing the frequency of the phasor~ before you've reached the loop area would completely mess up the caluclations of phase and/or frequency of the second phasor~, especially as you can only set the phase of a phasor~ once every block.

Why dangerous? And yes, when looping there's no advantage of rpole over phasor. For the first cycle that only plays once however, or for the case of playing a sample with variable pitch but without loop, the advantage of rpole is IMHO simplicity: you don't have to scale the input and output depending on sample length as with phasor. Show us the code! ;) Of course I will, as soon as I try it. This may work, but indeed would be very complicated. Also I assume, that changing the frequency of the phasor~ before you've reached the loop area would completely mess up the caluclations of phase and/or frequency of the second phasor~, especially as you can only set the phase of a phasor~ once every block. Not totally sure until i try and code it, but I think the phase of the phasor(s) (and the scaling factors) only need to be set up at the very beginning, and changing the frequency at any moment won't mess up anything since the frequency feeds both phasors (or both the phasor and the rpole) at the same time.

Re: [PD] best way to wrap opencv library for noob
I would suggest you try to modify pix_multiblob for better performance. This will get you familiar with C++, pixel processing, and how GEM is written. Also, and perhaps most important, you would learn what makes code fast or slow. The first clues for why pix_multiblob takes for ever to process are that it uses floating point processing and makes function calls inside the processing loop. AS far as 'wrapping' OpenCV the most basic method would be to build a lib and make calls to it for all of the processing. I don't think that will necessarily be very efficient though. Since you are a novice programmer you might also find a CV/tracking application that uses OSC or other network protocol to communicate with Pd.

Even with abstraction and patch saved into the same directory...what i'm missing? let's say you made an abstraction called 'myabs.pd', that is located in the same directory, where that main patch is located. now, when editing your main patch, you should be able to instantiate an object called [myabs]. if the surrounding box of the object [myabs] gets dashed, and you see an error in the pd window: myabs ... couldn't create that means, that pd couldn't find your abs [myabs] (which probably means, that it is NOT in the same directory as your main patch, e.g if you didn't save your main patch yet). if you don't see that error nor dashed lines, then everything is ok from pd's point of view. so, what exactly makes you think, that it does not work? 2) In sampling with soundfiler object, i cannot acess my samples, even adressing their directories in startup and paths, what's missing? soundfiles (or any other file besides pd-files) are not searched in the searchpaths by pd. that means you have to specify the filenames with the path like '/home/yoyo/mysoundfile.wav'. you could alternatively use relative paths (relativ to your patch). when your soundfile is located in the same location as your patch, then you can just use 'mysoundfile.wav'. note: as long as you didn't save your patch, the path of your patch is the same as the path of the pd start location. roman ___ Telefonate ohne weitere Kosten vom PC zum PC: http://messenger.yahoo.de ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] problem installing iem/adaptive library
Hallo Tania! I have started working with PD few weeks ago and I find it very useful for my work, but I am facing some problems in trying to load some libraries into PD. I want to add the Adaptive Filter library written by Markus Noisternig and Thomas Musil. I am working on Mac osx. This library is included in the pd-extended autobuilds from http://autobuild.puredata.org/auto-build/ - there you can download the osx version. Then you only have to start pd with pd -lib libdir -lib iem_adaptfilt. LG Georg ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Please help me out with this problem regards, tania hello tania i don't know, what is the proper way of installing externals on os x (if there is one). but i try anyway there are basically two things to consider: a) you need to tell pd, where it should look for externals b) you need to tell pd, which externals should be loaded on startup. in newer versions of pd, both can be done trough the menu (i don't recall the exact menu tree for pd on osx): pd-version - Preferences - Path: here you can add the path to your external pd-version - Preferences - Startup: here you can add the name of your external. on osx, the external would be a file called 'external.pd_darwin', but in the startup fields you only write 'external' withouth the file extension .pd_darwin. after entering, click 'save all settings' and 'apply'. then you should be able to instantiate objects from the new external. roman ___ Der frühe Vogel fängt den Wurm.

Re: [PD] Looping samples with tabread4~
Hallo, Matteo Sisti Sette hat gesagt: // Matteo Sisti Sette wrote: And yes, when looping there's no advantage of rpole over phasor. For the first cycle that only plays once however, or for the case of playing a sample with variable pitch but without loop, the advantage of rpole is IMHO simplicity: you don't have to scale the input and output depending on sample length as with phasor. Unfortunatly also rpole~ is quantized to blocks, when it comes to setting it's internal state through messages. See attached patch. Otherwise it would be a useful vline~ replacement. But as such it really requires working completely in the signal domain. Show us the code! ;) Of course I will, as soon as I try it. This may work, but indeed would be very complicated. Also I assume, that changing the frequency of the phasor~ before you've reached the loop area would completely mess up the caluclations of phase and/or frequency of the second phasor~, especially as you can only set the phase of a phasor~ once every block. Not totally sure until i try and code it, but I think the phase of the phasor(s) (and the scaling factors) only need to be set up at the very beginning, and changing the frequency at any moment won't mess up anything since the frequency feeds both phasors (or both the phasor and the rpole) at the same time. Hm, yes, that's right! Changing the frequency of the looping phasor~ B as well as that of phasor~ A should still let them both end at LB at the same time, at least if my considerations below are correct: To meet at LB the phase difference between both phasors (in samples) should be: d = (LB - SS) mod (LE - LB) which gets a bit simpler if SS is assumed to be 0: d = LB mod (LE - LB) Anyway the frequency of the phasor doesn't even show up in this formula, so the calculation is independent from frequency and thus should hold true for any changes in phasor frequency as well.

That's probably the crucial point where we disagree. AFAIK, it's well known that bold text is bad for reading. Having paragraphs of text in bold makes for slow reading, IMHO.

(Font size 12 in Pd/Linux is a problem for other reasons as well, as it takes away too much patching area.) One thing you might have overlooked is that Bitstream Vera Sans Mono is actually a bit smaller than Courier. Plus Vera Sans Mono reads lighter than other similar fonts, like Courier. I did not choose this font purely because of its looks, the Lucida fonts looked better. But it has to be free, and Lucida fonts are not free. If anyone finds a better font option, I am open to suggestions. This all would makes 10 point Vera text harder to read. It also makes 12 point more acceptable. For example, measuring this message box: [courier10( Bitstream Vera Sans Mono12 71x20 (Pd-0.39.2-extended-rc2) Courier 10 69x17 (Pd-0.40.2) That's not such a big difference.

Sorry to hear that. If you want to use it, you could compile it with the bold font, or help make a font preference so that everyone can choose their own font. .hc Ciao -- Frank Barknecht _ __footils.org_ __goto10.org__ ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/ listinfo/pd-list ¡El pueblo unido jamás será vencido! ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
