gem-0.84 for Win32 is out
by Mark Danks 07 Aug '00

07 Aug '00

Against all odds, GEM 0.84 for Win32 is out. You can get it at the usual place: http://www.danks.org/mark/GEM/ A lot of bug fixes, new example patches, new objects, etc. The release notes are at the end of the email. Please let me know if there are any bugs or issues. Later, Mark ============================ = mdanks(a)stormfront.com = Lead Programmer PS2 = http://www.danks.org/mark ============================ --------------------------------------------------------------- ---------------------------- 0.84 ----------------------------- I long time ago, I changed the behavior for gemhead, so that matrices where automatically restored, etc. However, this broke the camera object. Use the view message to gemwin instead. Fixed a bug in GemMan. If you didn't use "border 0" and you requested a window size with "dimen # #", then the window size was likely to be wrong. This is now fixed. Fixed a bug in the view message to gemwin. There was an offset which should not have occured. You might need to change your view messages to account for it. Just subtract 4 from any Z values. There are some examples for pix_snap in examples/gemAdvanced/gemPixSnap.pd - Single buffered example examples/gemAdvanced/gemPixSnap2.pd - Double buffered example Keep in mind that pix_snap is a fairly slow operation...I also fixed a nasty memory bug which could easily cause crashes. I added Miller Puckette's pix_video for linux into the code base. If you load a movie in pix_movie with an open message, the object will output the number of frames to the right output. This will not work if you have a "pix_movie homer.avi" for your object since the output message cannot get processed correctly at startup. The disk object has an inlet on the rightmost side for the inner radius...turning the disk into a ring. If the inner radius value is just 0., then the disk is just a circle. Fog can be turned on in gemwin. Look at examples/gemAdvanced/gemFog.pd for examples. The various control messages are documented in the gemwin.pd help patch. These next objects are thanks to hannes - mailto:zmoelnig@iem.mhsg.ac.at --------------------------- Added OpenGL material objects - ambient, ambientRGB, diffuse, diffuseRGB, emission, emissionRGB, shininess, specular, specularRGB They provide much greater control over the color of objects. Look at examples/gemLighting/gem5.materials.pd for examples. Guenter found a bug in the ortho object. It is now fixed. The ortho object has the same general unit size as the normal perspective matrix. Look at examples/gemAdvanced/gemOrtho.pd for how to use the object.

symbol (?) problem

Hi all, looking at the #key stuff recently, and trying it out, I find that using pack/unpack or select with symbols, e.g. route 0 1 a, gives me error messages and does the wrong things. obviously you all dont have this problem, as it occurs in the help /demoes too...any suggestions what i am missing? chz, tm -- -------- ------------------------------------ \ / Tim Boykett mailto:tim@timesup.org \ / TIME'S UP \/ Industriezeile 33 B /\ A-4020 Linz /xx\ ph/fax:+43/732-787804 /xxxx\ http://www.timesup.org -------- ------------------------------------ Watchout: http://gegenschwarzblau.cjb.net/

extern compilation
by Etan Fisher 03 Aug '00

03 Aug '00

hello, I am having trouble compiling externals under Microsoft Visual Studio. Should I compile the external first as a dll? The readme file contains the instruction to 'nmake pd_nt' but i could not locate any 'pd_nt'. HELP! (and many thanks) E. __________________________________________________ Do You Yahoo!?

IRIX n32 (irix6)linking problem
by Peter Lunden 03 Aug '00

03 Aug '00

Hi, I've tried to compile and run my externals with n32 format ( with pd-n32 ) but I get error from the realtime loader (rld) that it can not resolve any PD internal symbols (i.e. inlet_new ) this is also true for the precompile extras (i.e. bonk~.pd_irix6). Does anybody have a clue how to solve the problem. -- Peter Lunden ---------------------------------------------------------------- The Interactive Institute Box 24081 S-104 50 Stockholm Sweden Phone office: +46 8 783 24 59 Mobile: +46 70 461 20 56

RE: images -> audio

It is possible to sample pixel data and get the color values with the pix_data object. It accepts a normalized x, y position (ie, between 0, 1) and outputs the color and grayscale value of a pixel. You can use this to drive audio if you want.

images -> audio
by Michael Lechasseur 01 Aug '00

01 Aug '00

A visual artist would like me to create some audio from digitized brain scan images. I peeked at the objects in the GEM library, and they seem to deal with creating and displaying graphics, rather than using graphics as a source for output to "pure data". I seem to remember a friend telling me that pd and GEM were used at a demonstration at McGill university, and the patch was programmed to created audio from a graphic file. The processing of the data used to create the images would be fairly minimal. Any suggestions? Michael Lechasseur
