multiple window test
by B. Bogart 02 Feb '05

Hey Jamie, I just tried the multiple window Gem, unfortunatly its not working very well for me. I'm running 10.3.7 currently. So I can create two windows fine, but the square is not visible. After playing a bit I can't make anything show up in either window, just black. The console report is that the end of this message, it does say "shared 0" for both windows, perhaps thats it? Thanks Jamie! :) Here is the full console output: gemwindow::resetValues entered GemOutput::resetState entered dimenMess gemwindow::resetValues entered GemOutput::resetState entered dimenMess MAC: createGemWindow() gemwindow: create window 44D9E0 MAC: createGemWindow() GemwinMac: width - 500 height - 500 MAC: BuildGLonWindow entered MAC: BuildGLonWindow: fDraggable= false MAC: BuildGLonWindow: not draggable on single device MAC: BuildGLonWindow (!pcontextInfo->fDraggable && (numDevices == 1)) MAC: BuildGLonWindow exit GemWindow Activate err = 0 createGemWindow() finished hints: actuallyDisplay = 1 hints: border = 1 hints: width = 500 hints: height = 500 hints: real_w = 500 hints: real_h = 500 hints: x_offset = 0 hints: y_offset = 50 hints: fullscreen = 0 hints: border = 1 hints: display = (null) hints: title = GEM hints: shared = 0 hints: fsaa = 0 MAC: createGemWindow() gemwindow: create window 473BC0 MAC: createGemWindow() GemwinMac: width - 500 height - 500 MAC: BuildGLonWindow entered MAC: BuildGLonWindow: fDraggable= false MAC: BuildGLonWindow: not draggable on single device MAC: BuildGLonWindow (!pcontextInfo->fDraggable && (numDevices == 1)) MAC: BuildGLonWindow exit GemWindow Activate err = 0 createGemWindow() finished hints: actuallyDisplay = 1 hints: border = 1 hints: width = 500 hints: height = 500 hints: real_w = 500 hints: real_h = 500 hints: x_offset = 0 hints: y_offset = 50 hints: fullscreen = 0 hints: border = 1 hints: display = (null) hints: title = GEM hints: shared = 0 hints: fsaa = 0

osx multiple_window test
by james tittle 01 Feb '05

01 Feb '05

hey, ...I've put up a binary of the multiple_window test version for OSX on my homepage: http://homepage.mac.com/tigital ...this is compiled for G4's, so don't run it on a G3...included is an example patch, showing how the stuff works: if you don't send an offset message, by default the windows will be created on top of each other...to move them, cmd-click on the the windows title bar: this won't bring the window to the foreground in the finder (for reasons that are detailed elsewhere), but will allow you to move it around, even to another screen...I've only tested it on two powerbooks, so I'm looking for feedback on how it works with a computer with multiple display cards... ...also note that [gemwin] has been changed into an abstraction (included) to keep backwards compatibility... l8r, jamie ps; the multiple_window tag was branched about 6 months ago, so don't expect all of the fixes/changes since then, especially the vertex_array stuff...

freeglut / fglrx on fedora core 3
by patrick 31 Jan '05

31 Jan '05

hi, sorry for cross-posting this question (i wasn't aware of a gem-devel list), so i guess it's a better place to ask! ------------------------------------------------------------- i'm on fedora core 3 with ati driver (fglrx) for xorg. kernel 2.6.10-2.1.ll.rhfc3.ccrm - glut is not install, it's freeglut: /usr/include/GL/freeglut.h /usr/include/GL/freeglut_ext.h /usr/include/GL/freeglut_std.h /usr/include/GL/glut.h /usr/lib/libglut.a /usr/lib/libglut.so this is what i got when i'm trying to ./configure: checking for sin in -lm... no checking for main in -lz... no checking for glInitNames in -lGL... no checking for glInitNames in -lMesaGL... no OpenGL is mandatory this is my config.log: http://www.workinprogress.ca/pd/config.log what should i do? patrick

* Allow gemwin frame-rate to be set via message. * Add blending modes supported by openGL (which ones?) add/multiply/chroma/luma etc...? This is probably best done as a new "blend" object whose type can be set via message. The original "alpha" could stay, or be an abstraction something like: [inlet] | | [type alpha< | | [blend] | [outlet] B>

multiple_window: besides the mouse events...
by james tittle 28 Jan '05

28 Jan '05

...cool! found an easy fix for the triggerMouseEvent() width/height message output for a window... ...so, tonight I got the multiple_window branch to compile and run on OSX, but it's not running quite completely...so far it will create new windows (and apparently gl contexts) for each [gemwindow] object, and I have them hooked up to a [gemcontrol]. but only the last one created actually displays anything... ...have to admit that, beyond getting it to compile and all, I haven't really gone deeply thru the code to check out context sharing and such: is this working on xwindows atm? thanx, jamie

System and Gui blocking on OS X
by heimie＠selective.de 25 Jan '05

Hi there, i just read IOhannes` post on realtime and linux issues. perhaps this is something related, since the symptoms are pretty similar. so, if i do some video processing that it too much for my cpu (which happens quite often on my G3-900 iBook) my system is completely overloaded an i can not even kill the process, because i cannot access my terminal any more. the video is still running and being processed though, but i am out of the busines. the only way to avoid this is to set the "gemwin" to a low framerate. is there another way to do this? gem seems to try to get the maximum results at all cost. can somebody help me, please?! is there some way to lower the framerate dynamically at runtime or something like a framedrop external? regards, sebastian

fyi: linux+rt+gem
by IOhannes m zmoelnig 22 Jan '05

just to write it down somewhere: using pd in realtime-mode and Gem used to crash the system on linux (hard freeze) the problem used to be following: opening a glx-window when page-locking (with mlockall()) is enabled, makes pd use 100% CPU and you cannot kill it anymore. in combination with the realtime-scheduling this leads to a hard lock of the system: only rebooting helps but help is on the way: with kernel-2.6.10 it is now possible (again) to run pd in realtime mode and at the same time use Gem without having a hard system freeze. mfg.asd.r IOhannes PS: but be prepared to have some difficulties to get nvidia's drivers working with 2.6.10 ;-) hint: you have to replace "pci_find_class" with "pci_get_class" in the nv.c-file hint: and only 66.29 (which is the current version at this time) works for me

model-loader anyone ?
by IOhannes m zmoelnig 12 Jan '05

12 Jan '05

hi. as i have started a tiny bit to implement different model-loaders yesterday evening (it was late, so i didn't stopped anywhere usefule, but at least i started), and i do not want to double efforts i just want to ask, whether anyone has really implemented a loader for other models than .obj ? (jamie ??) i am at the stage defining an abstract ModelLoader-class, child-classes would then implement various file-formats (OBJ & 3DS of course; and most likely MD2 and MD3, as there are plenty of examples for quake-file-loaders out there) -- so not much work has been done on my side yet (this is: i could stop, if a lot of work had been done already on someone else's side) fmg.juzt.yx IOhannes
