[PD] Data structures: no object for freeing pointers?
I've been building a sequencer with data structs. But now I've come to a dead end, because there seems to be no object, that let's you remove structs. The only way seems to be deleting them in the gui. Am I missing something here? cheers, Jan ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

I think that is one of the limitations of data structures in Pd. You can clear a whole canvas, but not a single scalar, programmatically at least.

[PD] Data structures: Detect array changes
Hi all Actually, the same question applies to normal tables as well, but I know that plain Pd does not provide a way to detect changes, whereas Pd-l2ork does. What about data structure arrays? Is there some hidden way to detect changes? I can detect clicks, but I found nothing else.

Re: [PD] [rjdj] abstraction?
Hey Dan, It sounds like it could have been an abstraction to handle some functionality of the app way back in the early days i.e. recording. It's definitely legacy code. To be honest, some parts of the rjlib aren't really that necessary any more. For me most useful part of rjlib is all the dsp and list processing abstractions. At some point we even ditched the soundinput/output abstractions and used adc~/dac~ instead. In more recent apps a lot of functionality was moved to the objective-c side, which allowed the pd side to focus on what it does best, making cool sounds :) Cheers, Joe On 10 June 2013 18:40, Dan Wilcox danomat...@gmail.com wrote: Howdy, Does anyone who worked on/with the original RjDj app know what the [rjdj] abstraction does/did?

[PD] parsing XML
Hi list, I have a string2any object which is outputting XML that mostly looks like this when sent to a print object: print: updatesource id='1' level='-86.6183'//update print: updatesource id='1' level='-87.9314'//update print: updatesource id='1' level='-85.5559'//update print: updatesource id='1' level='-83.4277'//update print: updatesource id='1' level='-83.5981'//update etc. My patch doesn't need this information, only 'position' information, and when something important happens, data with x and y coordinates is outputted by string2any like this: print: updatesource id='1'position x='1.19286' y='0.992857'//source/update My patch needs to extract the x and y values as floats. I'm a bit rusty with Pd and I've not been able to work out how to do this. Can anyone please suggest what externals/techniques to use? Thanks!

(through the (semitransparent) front side of the sphere) Short answer: no. Long answer: no, because transparency and OpenGL don't quite get along as nicely as you might expect. Rendering order (of every triangle that makes up every object) matters a great deal. Transparency involves blending the current triangle with whatever is behind it. OpenGL uses its depth buffer to keep track of what's been drawn and how far away it is at each pixel - keeping only the nearest value - whether it was rasterized before or after the previous triangle. You need to draw non-transparent stuff first, then sort every transparent triangle into depth order, possiby splitting up any transparent triangles that intersect each other into smaller triangles, then render them in order urthest from camera first, nearest to camera last. I'm pretty sure that Gem doesn't support depth sorting. You might be able to hack it and get something that looks mostly ok some of the time by rotating the sphere to change the depth order vs render order of the triangles making up the sphere, but it will be very fragile... Claude thanks, i was expecting something like this. i guess i will think about an alternative approach to that instead of hacking around with depth sorting and rendering order within a single geometric object. matthias ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list Hello, I think it should be doable using culling (GL_FRONT and GL_BACK). But, in this case, you need to render two times the sphere (one with culling GL_FRONT and the other with culling GL_BACK) and then adjust alpha between them. ++ Jack ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Re: [PD] Data structures: no object for freeing pointers?
I find the data structure deign extremely limited and have been thinking for years about how to make it more powerful. I have a rather weak idea about alowing deletion of individual items in lists that I'm planning to try out in the run-up to the next release - not that that can help you right now. (In addition to the manifold problems that others have noted I'll add more fundamental ones: fundamentally clunky pointer mechanism difficulty of making numerically accurate changes on visual data structures (except by escaping to a text represntation ala 'properties' :) cheers Miller On Tue, Jun 11, 2013 at 03:04:10PM +0200, Patrice Colet wrote: Envoyé: Mardi 11 Juin 2013 11:25:23 Objet: Re: [PD] Data structures: no object for freeing pointers?

[PD] how to have multiple transports with only one clock
have a midi transport that sends a midi clock signal plus masterclock and it is used as a control in more than one place with or without patches that have it also to get them to not trigger each other when you start from one transport , send $0-masterbpm to where $0-masterbpm is needed in the patch then send out also plain old master bpm. this way if you want to start and stop the clock from multiple places you can. i probably ought to put back on the thinking cap about the matters but it worked to not start up 2 clocks for me when having 2 transports ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] Pd preferences dialog
Hi List, I'm nearly finished with a gui tab for the Pd preferences dialog I'm working on. Question: I (currently) have three notebook (tab) panes in the dialog: one for Audio, one for Midi and one for GUI. For GNU/Linux (and probably Windows) I have a Close button at the bottom right of the window, below the tabs. To the bottom left I have a Help button. I would like the Help button to bring up a patch that explains what the various settings in the dialog do. Should it just be one patch that is a catchall for all three panes (audio, midi, gui) or should it bring up a specific patch that's dependent on which notebook tab happens to be open before Help was clicked? I have a feeling it should be dependent on the specific tab that's open. (Not sure if that conforms to the Apple HIG but it's the way Firefox does it.) -Jonathan___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
