Yes. I currently don't have access to a PPC Mac with Fink on it. Anyone with Fink want to build readanysf~ to put together a release? I can help. Its mostly a matter of copying the right files, then using otool and install_name_tool to change the install locations. This shows you the libs its linked against: otool -L readanysf~.pd_darwin install_name_tool -change /sw/lib/libgavl.dylib /Library/Pd/readanysf~/ libgavl.dylib readanysf~.pd_darwin changes where readanysf~ looks for that lib. .hc On Oct 24, 2009, at 9:26 AM, hard off wrote: > is this only for intel macs? > > On 10/24/09, Hans-Christoph Steiner <hans(a)at.or.at> wrote: >> >> Woo hoo!

exploring polar-space in 1-bit (GridFlow 0.9.5 demo)
by mescalinum＠gmail.com 24 Oct '09

24 Oct '09

fooling around with gridflow lately (and I'm enjoying it a lot!) one nice addition in GridFlow 0.9.5 has been the c2p/p2c R² operators (respectively cartesian-to-polar, and polar-to-cartesian) just wanted to share this demonstration: http://dl.getdropbox.com/u/89643/gf_spirals_and_moire.avi as well as this: (not truly 1-bit though) http://dl.getdropbox.com/u/89643/gf_spirals_and_moire_take2.avi full ChangeLog for 0.9.5 release is at: http://gridflow.ca/svn/tags/gridflow_0_9_5_b/ChangeLog the patch I used to make the videos can be found in the examples directory of GridFlow (svn) cheers ~ mescalinum

On a sidenote: this is a really fast cam (up to 1 million pix per seconds) watch it: http://www.youtube.com/watch?v=LKR4atl8h-I but i guess that's a little to expensive for you :-)

In linux with a ps3 eye camera i've reached (thanks to kaswy - ps3 eye linux driver <http://kaswy.free.fr/?q=node/38#ps3>) 75 fps @ 640*480 125 fps @ 320*240 You can use more than one camera at a time - only tried with two cameras succesfully (i've only two of this:-) -> 60 fps @ 1280*480 (used form motion tracking purpose) (OT: the only problem I have is: how to compose the two images into one single image to feed a single pix_blob? If someone can help...) The video quality is excellent (compared to other webcams) - a little noisy in low light but very good in normal light. You can choose Exposure, color balance etc... (auto or manual) The lenses have 2 zoom factor 56 and 75 degrees. There is the possibility to hack the hardware and have a M12 lens mount on it to have a wide range of lenses. Last, but not least: the price is very very low compared to other solutions (40 euros each). ciao!
