Re: [GEM-dev] more problem due to recent gem update
by cyrille henry 29 Aug '10

29 Aug '10

after an other Gem update, i found a problem it concern most (all) primitive, and even other object (pix_video by example) when this objets are create after the windows creation, they did not really work. you have to destroy/create the Gem window in order to see a new primitive. this cause major problem, i'll have to revert to an older gem version until it is fixed... are you trying to implement multiple windows?

TIFF files from pix_buffer (and others?) missing some "standard" tags?
by B. Bogart 06 Aug '10

06 Aug '10

Hey all, I've had trouble loading some TIFs generated in pd/Gem in PIL (python imaging). I asked on the list and it seems PIL expects some particular TIF tags being set in order to recognize the image. I think it can only be an improvement to add these tags so that tifs generated in pd/Gem can be loaded by as many applications as possible. The attachment contains the specific tags. Thanks, B. Bogart

svn update break rectangular texture with shader
by cyrille henry 28 Jan '10

28 Jan '10

hello, i just did an svn update. lots of file have changed. (last update was 21 december) after building gem, i realized that few shaders example did not work any-more. it look to be related with rectangular texture : if you open shader example 1 : simple texture : it work ok with non rectangular texture (but the texture is upside down), but it does not work at all in rectangular mode... hope that could be fixed soon thx, Cyrille

The idea would be to run these on the build farm machines every night automatically, so it would be valuable to have, IMHO. You can have shell access to the build farm machines, if that's helpful. The Mac OS X 10.4/Intel machine is a Macbook Pro, so its got a pretty good graphics card. The rest are very old. .hc On Jan 15, 2010, at 4:39 PM, cyrille henry wrote: > > > Hans-Christoph Steiner a écrit : >> In audio land, you can count on Pd to give you the exact same >> stream of numbers for the same operations (i.e. determinism).

In audio land, you can count on Pd to give you the exact same stream of numbers for the same operations (i.e. determinism). I don't know enough about OpenGL to know if you can count on it to give you the exact same stream of numbers for a given set of operations. If so, you can render a reference image, then to test, make a render image, then check it against the reference. .hc On Jan 15, 2010, at 4:22 PM, cyrille henry wrote: > hello, > > i have no idea how to make a patch that could automatically test if > it work or not. > the pb is that it just don't look like it should, but there is no > error anywhere... > > maybe we could have a set of patch that could write pictures on a > HD, and compare them to what it should be. > but i think it is a not very clean solution. > what do you think? > > c > > > Hans-Christoph Steiner a écrit : >> In a semi-related note, I'm trying to start gather patches for >> automatic regression testing.
