mipmap support for pix_texture
by Claude Heiland-Allen 27 Mar '13

27 Mar '13

Hi! I tried adding mipmap support, with some success. Patch against current git attached. Activate it by sending [rectangle 0, quality 2( to [pix_texture]. Results will have glitchy edges if your image is NPOT (not a power of two size in each dimension), but it does looks a lot better for POT images - far less aliasing when the displayed size is smaller than the image size: http://mathr.co.uk/misc/2013-03-26_pd-gem_mipmap.png (from left to right: nearest, linear, linear_mipmap_linear) There are still some bugs, in particular relating to sharing textures between multiple [pix_texture] objects - not sure what's going on there (I'm not too familiar with Gem internals). I'm also not sure which version of OpenGL introduced glGenerateMipmap(), maybe that needs checking at runtime to avoid crashes? (Also some weirdness with my fresh git clone in that 'git add help/pix_texture-help.pd' did precisely nothing, so I attached my modified version too.) Hopefully this is useful, Claude -- http://mathr.co.uk

feature request : support for 16bit images (and more...)
by Antoine Villeret 21 Mar '13

21 Mar '13

hi, I think Gem only supports 8bit images. Could it possible to add support for 16bit images ? Some cameras send 16bit data stream (kinect, but also most of industrial camera have a 16bit mode). It could be more convinient to use those data as is without the need to parse LSB and MSB into 2 channels. This can also improve performance. Kind regards antoine -- do it yourself http://antoine.villeret.free.fr

pix_share_write error
by Antoine Villeret 19 Mar '13

19 Mar '13

hi, i'm experiencing some strange behavior with pix_share_write/read sometimes i get this error when setting pix_share_write : couldn't get shm_id: error 0 but i couldn't reproduce this, it seems it happens when a patch with pix_share_write crashes (due to errors in a V4L2 device) after reloading the patch, pix_share_write can't initialize correctly it happens not so often, but when it does i can't understand why and I have to change the ID in the [set( message to find a working one I made few changes in the code of pix_share_* to forward the error though an outlet so I can automatically try another ID this is in my github repos in the branch pix_share_write : https://github.com/avilleret/Gem/tree/pix_share_write I don't know if it's a good idea but it seems to work for me I'm wondering if it could be good to have a dictionary instead of a hash table : when we use [set id sizex sizey pixel_format( message, pix_share* could try to find the id in the dictionary if there is no entry with that id, it generates a random shmem id, verify that nobody else is using it and tries to allocated data if it fails it could generates another id until it succeed and store the id in the dictionary pix_share_read will know the dictionary and can find the right shmem id what do you think about that ? kind regards antoine -- do it yourself http://antoine.villeret.free.fr

upgrading Gem's sourceforge project
by IOhannes m zmoelnig 19 Mar '13

19 Mar '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi all, i'm currently thinking of upgrading the "pd-gem" project on sourceforge, since sf seems to want drop support for the older system on the long run (and i'd prefer to do it while i can choose when to do it). some information on the upgrade process can be found at [1]. i think the main difference we will experience is, that the repository address will change. OLD: ssh://pd-gem.git.sourceforge.net/gitroot/pd-gem/Gem NEW: ssh://git.code.sf.net/p/pd-gem/Gem (or git:// rather than ssh:// for anonymous checkouts) from other projects i have migrated it seems that the old repository will stay available, but they won't get automatically synched after the migration (which might to lead to some confusion until everybody uses the new URL)(btw, it seems to be possible to manually push to the old repository for now) if somebody has objections, they should speak up, f gamdr IOhannes [1] https://sourceforge.net/p/upgrade/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAlD4H7kACgkQkX2Xpv6ydvSB1ACg46B7sEzi9iFmgqEojbrGlHkx OAsAn1wHNqDD8KT/CGIaxtqkZzXwPZ09 =KCM8 -----END PGP SIGNATURE-----

2 gemwin with a switch
by Elektro Moon 01 Mar '13

01 Mar '13

Gents, I would like to control 2 patches with 2 separate Gemwins, where with one bang from a [send] object I create from 1 patch a gemwin while destroying the other Gemwin in the other patch. For some reason the processor is extremely slow when I add to gemwin a numeric sign like [gemwin 1] and [gemwin 2]. If I do not indicate gemwin any way, the sender switches off both gemwin at once or printing that Gem window is already created. What is the right solution? Thanks in advance: Popesz

Gem on Ubuntu 64bits
by jack＠rybn.org 21 Feb '13

21 Feb '13

Hello, I would like to know if it is a good idea to install the last Gem and last pd vanilla on an Ubuntu 64bits? Is there some problem with 64bits Linux Systems and Gem ? I used to use Ubuntu 32bits until now, but i bought a new laptop with Windows 8 and UEFI boot mode. And with this boot mode it seems that i can only install an Ubuntu 64bits (until there is a 32bits available). Yep, i want a dual boot with Windows. Thanx. ++ Jack

(Originally Pd-ext bug tracker #ID: 2936861) -Jonathan Pd version 0.42-5extended-20091215 If you pass a pix signal trough a pix_puzzle the image gets scrambled like it is suposed to, but if you cut the connection the image stays scrambled even if you delete pix_puzzle. It goes back to normal if you bang pix_puzzle when the sinal is not passing trough. It is not very problematic ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=507079&aid=3605473&group_…
