Externals - Compilation or Usage Problems
by Chris 29 Apr '07

29 Apr '07

Hi, I checked out the documentations from CVS because I wanted to try the External-making-howto. I compiled the helloworld-example there with the included Makefile. Compilation worked without any problems, but when I try to to load it in PD with pd -lib /home/chris/pd_externals/example1/helloworld.pd_linux it says "can't load library" What am I doing wrong? Thanks in advance.

array data in abstractions
by Peter Worth 29 Apr '07

29 Apr '07

Hi everyone. If i have an abstraction with an array in it, is there any way for the data to be saved in any parent patch which instantiates the abstraction, rather than in the abstraction itself? in my main patch i want lots of copies of the abstraction each with different data. Thanks for any help.

GEM GOP abstractions
by Chris McCormick 29 Apr '07

29 Apr '07

Grtz, I've been messing with GEM lately and have made a bunch of GOP abstractions to make things easier. You can find then in the tarball of my cvs which is at: http://mccormick.cx/viewcvs/s-abstractions.tar.gz?view=tar The gfx stuff is in the sx/ directory and works best if you include the parent directory (s-abstractions/) in your path. You'll need the zexy (for [repeat]) and Gem libraries. I have always found it strange how GEM seems to be kind of backwards in terms of the flow of data. In Pd you generally make a noise with e.g. [osc~] and then run it through some effects, into your [dac~] where it is output. In GEM it works the opposite way. You have to place all your color, translate, rotate, repeat, texture "effects" before you put the basic geom such as [cube], and the whole chain starts with the "output" [gemhead]. To address this I've been experimenting with a method of storing geometry in a [list] which is sent through geometry modifying "effects" to an object [sx/blob] which draws geometry represented as a list of verticies of triangles, to the screen. It's pretty crap and slow, and I'd love to know if there is already a better way of doing this. You can send arbitrary geometry from blender3d into puredata by using the script in the utils/ directory. Copy it into your .blender/scripts/ directory and go File... Export... Raw Triangles across the Net... whilst having sx/netgeom-help.pd open. You can't send very complex geometry or the whole thing starts to chug pretty badly, but I think it's a start for something better. An example of an effect on geometry is the sx/explode patch which translates all faces along their normals by some amount. This is all done as [list] math so it's hellishly slow on complex geometry. I am particularly interested to hear if there is a better, faster way of doing this [vector level geom manipulation] that I don't know about. I have been really inspired by the fijuu stuff and I would like to be able to do similar kinds of mesh warping from withing Pd and GEM. Best, Chris. ------------------- chris(a)mccormick.cx http://mccormick.cx

Gem Compiling
by Nose Hair 29 Apr '07

29 Apr '07

I've been trying unsuccessfully to compile gem with font support for PPC running os 10.4.9. I have got as far as compiling freetype2, cppunit and FTGL but when I go to run the Xcode project to compile gem_darwin, I get a bunch of errors like "Base/configDarwin.h no such file or directory" when I see the file in the directory, among many other errors. I also tried to compile using ./configure and make but I get glsl_program.cpp: In member function `virtual void glsl_program::LinkProgram()': glsl_program.cpp:411: error: 'kCGLCPGPUVertexProcessing' was not declared in this scope glsl_program.cpp:412: error: 'kCGLCPGPUFragmentProcessing' was not declared in this scope make[1]: *** [glsl_program.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make: *** [Manips] Error 2 I have the most recent cvs stuff so I dont know what to do. I was able to compile the gemlibs just fine but I guess the full echilada takes a little more knowhow. Any help would be awesome. Thanks, Alain

turning off audio in abstraction objects
by c.m.bryan 29 Apr '07

29 Apr '07

Hello all, I seem to remember a way to turn off audio in specific objects within a patch, by now I can't find it. I have multiple instances of a particularly intensive abstraction, it would be helpful to conserve resources for the ones that aren't currently being heard. Any hints? Thanks, Chris Bryan

Flute synthesis
by Jamie Bullock 28 Apr '07

28 Apr '07

Hi, Does anyone have any experience doing synthesis of Flute sounds in PD? I am looking for a physical modelling style synthesis like that promised by [flute~] from Percolate. Sadly this external doesn't work on my machine. I am about to try to get STK support via flext, and will report back if successful. Any other advice on this matter would be appreciated. Jamie

Re: [PD] bang on ~ 0 crossing?

Hi, I think the [threshold~] object should do exactly what you ask, would be more accurate than the [snapshot~]+[>~]+[metro] approach and perhaps even cheaper, and it does not require any external either.
