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

gemvertexbuffer
by Antoine Villeret 03 Sep '11

03 Sep '11

hi all, Cyrille and me made [gemvertexbuffer] object while we were trying something with OpenCL. This object fillin a VBO (Vertex Buffer Object) with pd tables values. It looks like scopeXYZ but we think it's more flexible. It's very fast (100000 points @ 250 fps on a Nvidia Geforce 9400M). We know that something similar already exists in the vertex folder of Gem but we need to do it by ourself to better understand VBO workflow. As we learned a lot of things doing this, we hope that it could help someone else, so we share it... It has been test on Ubuntu. If you want to build it, you just need to adjust paths in the Makefile and run make. Cheers Antoine -- do it yourself http://antoine.villeret.free.fr http://drii.ensad.fr -- Google lit ce mail... si vous refusez cela, utilisez l'adresse antoine.villeret [at] free.fr pour me contacter

switching to git
by IOhannes zmölnig 29 Aug '11

29 Aug '11

hi all, in the last year (or so), i have changed my personal development workflow over the last year or so, to almost exclusively use git as the version control system. Gem development has been done in git as well, with only an occasional push to the SVN repository. this has somehow worked, but it left lots of things to be desired, and left me with a number of problems (most recently a branching/tagging dance for the 0.93 releases). git has a number of really nice features that i use, most prominently that i can commit unstable code and only push it to the main development branch once it is finished, but still keeping all the commit history. another nice feature is, that i can work at home (where i don't have internet) and still commit regularily. it's quite easy to simlutaneously try things out on multiple machines, without polluting the public repository. branching and merging is trivial. patches by 3rd party (e.g.: you!) can keep the full authorship and log information. and finding regression bugs is made super easy by tools like "git bisect". given that i am the one who writes most to the repository, i did not raise a real discussion about this topic but rather silently decided to officially switch from subversion to git. in the future i will try to not update the SVN anymore, and instead only work in git. if you want to track my changes (or commit yourself), please use these URLs read only: git://pd-gem.git.sourceforge.net/gitroot/pd-gem/Gem read/write ssh://USER@pd-gem.git.sourceforge.net/gitroot/pd-gem/Gem (with USER being your sourceforge username) i hope this is fine for everybody. gfmasdr IOhannes

MinGW build progress
by Hans-Christoph Steiner 25 Aug '11

25 Aug '11

Hey IOhannes and all, I'm wondering if now is a good time to continue with the MinGW porting. If not, I'll just remove Gem from the Windows nightly build. Any ideas on the -rpath being blank, IOhannes? I'm stumped, and I thought you might have some insight since you wrote most (all?) of the autotools stuff. .hc ---------------------------------------------------------------------------- If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of everyone, and the receiver cannot dispossess himself of it. - Thomas Jefferson

gem and openCL
by cyrille henry 25 Aug '11

25 Aug '11

hello, Antoine and I are very interested on the cuda for Gem work that we saw on the pd conv. But the main problem is that cuda is nvidia limited. OpenCL does not have this limitation, so we think it's a better choice. Antoine successfully made openCL example as a Gem object. but we are wondering how to create a generic object. OpenCL allow to deal with diferent type that are not really implemented in Gem (VBO by example, 3d texture), nor in openGL (boolean texture). I don't really like the solution to have : - ocl_vbo object that allow to create and use a vbo - ocl_3dtexture for 3d texture rendering - ocl_bool_texture ... So, did anyone have an idea about what should be done? thanks Cyrille

NVidia optimus on Linux and Gem
by jack＠rybn.org 25 Aug '11

25 Aug '11

Hello, I would like to know if people on this list use a NVidia graphic card with Optimus on Linux and Gem and tell us if they encounter problems ? I would like to buy a new laptop but i read in different forum that NVidia doesn't plan to develop a driver on Linux using this technology. I also read that this technology with i5 Sandy Bridge and NVidia GT 540 might suffer of throttling (that could be a big issue in a peformance using Pd and Gem). I am looking for a good laptop to use Gem with a weight < 2.2 kg. Thanx. ++ Jack
