Problem with some OpenGl related objects
by pier caros 26 May '14

26 May '14

Hello everybody, While opening the simple_texture patch in GEM examples I get these problems:[glsl_vertex]: need OpenGL-2.0 (or at least the vertex-shader ARB-extension) to run GLSL[glsl_fragment]: need OpenGL-2.0 (or at least the fragment-shader ARB-extension) to run GLSL[glsl_program]: openGL-2.0 (or at least ARB shader extensions) needed for GLSL I'm using a laptop running windows 7 and equipped with Nvidia Geforce 820m graphic card and the last version of PD extended (0.43.4)Any idea on how I can solve this problem?Thanks

Gem Window Grab - Output Freeze
by j-p 20 May '14

20 May '14

Hi, Question about a small issue with Gem - wondering if the solution might be an easy fix. While grabbing the Gem window (not-fullscreen) and moving it around, the motion in the output freezes until mouse-up. Not such a big deal for self-testing or performance, as it would be fullscreen, but for a standalone app, a problem for the user. Any interest for fix? Thank you. J

how to make PD display Russian words with text2d \ 3d ?
by Фывапр Олджэвич 20 May '14

20 May '14

Hello, dear list ! I'm trying to built a kind of interface in PD, for which i need to render a lot of text in Russian to the GEM-window. I found out that PD doesn't understand cyrillic letters at all. I tryied to push text from [textfile] to [text2d] directly, but it also displays like " õóé õóé1 õóé2 õóé3 " - which is not what i need. In cyrillic this should be displayed as " хуй хуй1 хуй2 хуй3 " Any advice please ? Thaks !

hello, according to the mailling list, there is a mails that I did not received. so, i added a framebuffer type : RGBA32. The only 32 bits type available in Gem was GL_RGB_FLOAT32_ATI that was introduce in order to make some bump mapping. Latter, 32 bits type was used for physical modelling or other GPGPU stuff. But this type is not available on intel gpu, at least with current driver under linux. So, i just added a 32bit type that can be used. i did not tried it for bump mapping (years ago, GL_RGB_FLOAT32_ATI was the only one allowing bump mapping with good performance). It would be nice that Gem choose what type to use, but I don't know how to do this choice when many type are available. I think they are not equivalent depending on what you want to do. So the easiest solution is to test them on each combination of patch / hardware. moreover RGBA32 is a 4 channel type, while GL_RGB_FLOAT32_ATI is only 3. cheers cyrille -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 On 2014-05-13 12:58, Cyrille Henry wrote: > > add a new 32 type for framebuffer (since GL_RGB_FLOAT32_ATI is not > usable with intel GPU on linux) wouldn't it make more sense to have a single float32 type on the patch-level ("RGB32"), and use whatever is available on the given GPU? mfgasdr IOhannes
