problem with [pix_mask]
by Jack 08 Nov '11

08 Nov '11

Hello, Is it normal that i get transparency when i use [pix_mask] in my example. It seems the white pixels from dancer.JPG are not enough white. Even with [pix_duotone] on dancer.JPG to get a white (1,1,1) and a black (0,0,0), it is still the same. Any idea to avoid this problem ? ++ Jack

performance question with linux and nvidia
by cyrille henry 24 Feb '11

24 Feb '11

hello, i've got performance question regarding Gem an openGL. i made a test using an OS on a custom liveUSB, so that i can have the same software environment on 3 different computers: ubuntu 10.04, NVIDIA driver v270, pd vanilla 42.5, and Gem svn. this computer are: very old laptop: intel core 2 / GeforceGo 7700M old laptop: intel core 2 duo / Geforce 9650M gt new laptop: intel core i7 / Geforce GT 425M i made a test with glsl performance, and everything is normal : a newer computer is many time faster than the older. BUT, using a very simple patch (like attached), drawing only many time the same square, i can't see any really significant performance difference. how could that be? what can be the botleneck? (with "lighting 0", i can draw about 400 square before the fps goes down) but i've got a bigger problem : with "lighting 1", the 2 old laptop can draw about 10% less square (than with lighting 0). but the new one can draw only 3 times less square. So the new laptop is lot's slower than the old one when light is on. does anyone already experience something like this? any idea why, and how to solve this? thanks Cyrille

AA with shader
by Jack 30 Jan '11

30 Jan '11

I know, this is not a specific GEM problem. I would like to get the render (started with only geos) from the [gemframebuffer] anti-aliased. And I was wondering if someone has worked on a shader to get this effect and if this person would like to share his shader or to help in development ? Thanx. ++ Jack

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi, would it be a problem for you if we moved this thread onto a mailing list? i really prefer this way of communication, as it allows more than a single person to profit (and help!)

(i'm not sure about this though). but even if i implemented user buffer support, i still would need to know which transport is actually used and thus the "query" has to succeed. > > maybe this is normal, but im not able to set properties: > directly setting menu-value to 'Composite 1' (please report if this works!) > verbose( 1):could not set property 'source' unfortunately i cannot test menu-values, as i don't have any device that offers a menu-value :-.( just to make sure: how exactly do you try to set your source? i think it should be something like: |...\ (symbolbox) | [set source $1( | [pix_video] and then type "Composite 1" into the symbolbox (this is an easy way to create a symbol with spaces) another way that _should_ work, is [set source 0( | [pix_video] if you can confirm that this (source <int>) works and that (source <symbol>) does not, i have an idea how to fix the underlying code) apart from all that, i found that unicap does not reliably start the transfer. e.g. using my PS3 i have to first set the size with "dimen 640 480" to the only support dimension of the device (i'm using the normal kernel drivers), since unicap always believes that the only supported size is 768x576, but then fails to capture images. it is also crucial in which order things are called (e.g. i have to do [dimen 640 480( and only then start rendering/capturing/transfer, else i don't get an image for the rest of the Pd-session. on my eeePC, it is slightly different, but i have to explicitely set the device before i can acquire images. all in all, unicap support is still quite experimental. i'm using stock debian's unicap though, which is a bit outdated (0.9.5) fgmasdr# IOhannes -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk09NjkACgkQkX2Xpv6ydvS7MgCg9TBzoXaOVP/gnu5Cvvq5PMBe FDEAoMnBpmDGDF79D5VE/l9z/vodc+cV =kopB -----END PGP SIGNATURE-----
