Making multiple gem curve3d objects seamless
by B. Bogart 22 Jul '05

22 Jul '05

Hey all, To get around the issues of curve3d matrix size I'm hoping to use multiple curve3d objects to create one surface. The biggest problem I'm having is makes the curve surface seamless. Even with variable overlap between "patches" I always see the seams. :( So if the max matrix size bug could be fixed, or a method of seamlessly joining curve3d objects would be great... 4x 8x8 curve3d's perform fine on the laptop.. (have not tried on linux due to a numarray/py issue) Any hints would be appreciated. Thanks all! b>

fullscreen on second screen linux does not work
by B. Bogart 15 Jul '05

15 Jul '05

Hey all, I'm experimenting with a touch-screen I have on loan. I've configured by X server (nvidia driver) not for twinview, but for multi-head (:0.0 and :0.1). I can open a full-screen window on 0.0 fine: [dimen 1280 1024, fullscreen 1, create :0.0 < But if I try and do the same on the second screen: [dimen 1024 768, fullscreen 1, create :0.1 < or [dimen 1024 768, fullscreen 2, create :0.1 < Gem only creates a normal window with a title-bar and complains: GEM: creating gem-window on display :0.1 error: GEM: fullscreen not available on remote display :( I don't see why the second display should be any different? I'm looking into running no display manager on the second screen, but using gnome it does not seem so clear how to run only on 0.0 and not on 0.1. Any tricks ? Thanks all! b>

compiling gem with mingw - almost there ...
by Thoralf Schulze 13 Jul '05

13 Jul '05

Hi there, especially Johannes, the never-ending story continues ... but the end is getting near. After having a look at the ms psdk, I decided to comment out the offending lines in pix_videoDS.h (1271-72): wsprintfW(wsz, L"FilterGraph %08x pid %08x", (DWORD_PTR)pUnkGraph, GetCurrentProcessId()); Am I right with the assumption that the above line just prints out some debugging stuff? According to the MS PSDK, wsprintfW is deprecated and should not be used anymore. They recommend using StringCchPrintfW instead, but that didn't work either - in any case, they didn't manage a smooth transition ...Will it do any harm do gem if this statement is missing in the dll? Furthermore, I ran into some trouble with partlib_actions.cpp : including iostream.h instead of iostream doesn't work with mingw, iostream works quite well on the other hand. Since iostream.h is necessary for vc6, I changed this block to: #if defined __WIN32__ && !defined __MINGW32__ /* jmz: at least my vc6 doesn't like linking against the "new" io-libraries * with <iostream.h> it links against the old libs */ #include <iostream.h> #else #include <iostream> #endif which compiled fine. Another issue in this file is the use of the drand48() function, which was missing. It gets defined in part_vector.h, but the function was still missing after I included this file in partlib_actions.cpp. Looks like the WIN32 definition gets lost somewhere inbetween? I resorted to copy&paste the definition #ifdef __WIN32__ #define drand48() (((float) rand())/((float) RAND_MAX)) #define srand48(x) srand(x) #endif into partlib_actions.cpp, that worked. I realise that these are quite ugly hacks, but I just want to get the cvs gem compiled with mingw ... Another issue is linking all the .o-files into a dll - command line for dllwrap.exe is getting too long ... bummer. with kind regards, thoralf. ___________________________________________________________ Yahoo!

configure (again): call for testing....
by IOhannes m zmoelnig 08 Jul '05

08 Jul '05

hi all i have adapted gÃŒnter's build system (and of course, overcomplicated things again ;-) :-( ) i have checked it into Gem/src and i do think it is ready for testing by now. features: moved from src/Gnu to src checks work (e.g. for ARB-extensions) dependencies are generated on the fly (no need for Make.depend) source-files are generated on the fly (no need for Make.source) source-files containing white-spaces are ignored partial compilation support (e.g. skip openGL/ if you don't want it) usage of pkg-config automatic checking for apple-frameworks ... caveats: i just _had_ to: add my own m4-code, esp. for package-detection (this is: per default use PKG_CHECK_MODULES, fall back to AC_CHECK_LIB ffmpeg-detection seems to work on my machines, but i am not sure whether it really does. GemLibs might be a bit ignored without manual tuning. m4-features: added checks for flags supported by the compiler overcomplicated package-detection (see above: using PKG_CHECK_MODULES and as a fallback AC_CHECK_LIB) m4-caveats: haven't found a way yet how to test for special linker flags. file-layout: src/acinclude.m4-(aclocal)->src/aclocal.m4-+ |-(autoconf)-> src/configure src/configure.ac---------------------------+ src/Make.config.in ---------------(./configure)-->src/Make.config src/Base/config${KERN}.h.in --(./configure)-->src/Base/config${KERN}.h with ${KERN} being $(uname -s) (Linux, Darwin,...) src/Makefile includes src/Make.include includes src/Make.config master-makefile, cd's into subdirs and calls make there src/Makefile.subdir includes src/Make.include includes src/Make.config makefile for subdirectories (called via "make -f ../Makefile.subdir") both the old and the new build-system can live together (with the old build-system having files in src/*/ and the new one _only_ in src/) in theory, you just need to check it out, cd to Gem/src and run "make" everything (including aclocal.m4 and configure) should be built as needed. would be great if someone could test it (at least on linux-flavours and osX; i fear w32 will not work out of the box, but who knows) mfg.asd.r IOhannes

filmQT.cpp - compilation woes

Gem says quicktime ok, then disagrees with itself
by B. Bogart 07 Jul '05

07 Jul '05

Hey all, I got Gem-CVS compiled on OSX now but upon trying to load a DV quicktime movie was suprised that Gem is contridicting itself. :( After autoconf && ./configure I get: video-support use mpeg : no use mpeg-3 : yes use QuickTime : yes use aviplay : no use ffmpeg : yes All great, then when I create a pix_movie I get: pix_film:: libffmpeg support pix_film:: quicktime support pix_film:: libmpeg3 support Still looking good. When I try and load my DV quicktime: FFMPEG: unsupported! quicktime4linux: unsupported! MPEG3: unsupported! error: GEM: pix_film: Unable to open file: /raid0/media/dv_capture1.mov Gem suddently decides that ffmpeg, mpeg3 and quicktime are "unsupported" Wha? I have installed: ii libmpeg-dev 1.3.1-2.1 Header files and static libraries for the MP ii libmpeg1 1.3.1-2.1 The MPEG library calls for movie streams ii libmpeg2-4 0.4.0b-2 MPEG1 and MPEG2 video decoder library ii libmpeg3-1 1.5.4-4 MPEG streams decoding library ii libmpeg3-dev 1.5.4-4 Headers and static libraries for libMPEG3 ii libquicktime-d 0.9.3-2 Header files for developing applications wit ii libquicktime1 0.9.3-2 A library for reading and writing Quicktime Ah well I'm trying to get mplayer from nerim.net but the damn download keeps disconnecting, so ffmpeg is not installed... (though probably was when I compiled Gem a few moments ago) Does anyone know of a mirror of what is on nerim.net/debian-marillat ? I think it considers my 33.6 too slow and keep dropping me off. :( Thanks all. B>

more OSX 10.3 compilation - class_set_extern_dir
by g�nter geiger 07 Jul '05

07 Jul '05

Hi, My compilation of Gem just stopped at this function in pix_freeframe .. considering that the function is not exported from pd, I was wondering what it does and why it is used (and why only under OSX). For the moment I just removed it to be able to go on with the compilation. Guenter

clear message to gemwin
by Thoralf Schulze 28 Jun '05

28 Jun '05

Hi Ben, hi list, > Anyhow I proposed a "clear" selector that could be > changed without > destroying and re-creating the gemwindow. (I hope) > basically a nice > feature for "trails" so that single-buffering is not > depended upon for > "not clearing" so this boils down to still running GEM in double-buffered mode, but having to manually clear the window if the default behaviour (totally clearing the gemwin after each rendering cycle) has been changed, right? That would emulate the single buffered mode ... and once again, it would be a nice feature to have. I've been thinking about the possibility of implementing this feature on a per-geo-basis (best of both worlds) - but this is probably impossible to implement. with kind regards, thoralf. ___________________________________________________________ Yahoo!

compiling GEM for Win with gcc
by Thoralf Schulze 24 Jun '05

24 Jun '05

Hi there, I'm still struggling to get the cvs version of GEM compiled for Win with gcc (dev-c++). DSgrabber.cpp includes some microsoft header files, with winnt.h being one of them. Unfortunately, this one incorporates some inline assembler, like this: #if _MSC_VER >= 1200 #pragma warning(push) #endif #pragma warning(disable:4035 4793) // re-enable below __inline ULONGLONG NTAPI Int64ShllMod32 ( ULONGLONG Value, DWORD ShiftCount ) { __asm { mov ecx, ShiftCount mov eax, dword ptr [Value] mov edx, dword ptr [Value+4] shld edx, eax, cl shl eax, cl } } This seems to be the Intel flavour of assembler notation, while gcc defaults to the at&t one. Unfortunately, -masm=intel doesn't help: Executing make... make.exe -f "D:\Dokumente und Einstellungen\VJ\Eigene Dateien\GEM\Gem\src\Makefile.win" all g++.exe -c Pixes/DSgrabber.cpp -o Pixes/DSgrabber.o -I"." -I"./Base" -I"../../pd/src" -I"../../GemLibs/freetype2/include" -I"../../GemLibs/tiff/libtiff" -I"../../GemLibs/JPEG" -I"../../GemLibs/wintab/include" -I"../../GemLibs/FTGL/include" -I"D:/Programme/Microsoft Platform SDK/Samples/Multimedia/DirectShow/BaseClasses" -I"D:/Programme/Microsoft DirectX 9.0 SDK (February 2005)/Include" -I"D:/Programme/Microsoft Platform SDK/Include" -D__GNUWIN32__ -mcpu=pentiumpro -D_M_IX86=600 -W -finline-functions -DNDEBUG -DWIN32 -D_WINDOWS -DNT -D_LANGUAGE_C_PLUS_PLUS -DWIN32_LEAN_AND_MEAN -DGEM_INTERNAL -masm=intel -O2 -march=i686 -msse In file included from D:/Programme/Microsoft Platform SDK/Include/windef.h:176, from d:/programme/Dev-Cpp/Bin/../lib/gcc/mingw32/3.4.2/../../../../include/excpt.h:20, from D:/Programme/Microsoft Platform SDK/Include/windows.h:157, from D:/Programme/Microsoft Platform SDK/Samples/Multimedia/DirectShow/BaseClasses/streams.h:41, from Pixes/DSgrabber.cpp:13: D:/Programme/Microsoft Platform SDK/Include/winnt.h: In function `ULONGLONG Int64ShllMod32(ULONGLONG, DWORD)': D:/Programme/Microsoft Platform SDK/Include/winnt.h:588: error: expected `(' before '{' token D:/Programme/Microsoft Platform SDK/Include/winnt.h:588: error: expected asm body before '{' token D:/Programme/Microsoft Platform SDK/Include/winnt.h:589: error: `mov' undeclared (first use this function) D:/Programme/Microsoft Platform SDK/Include/winnt.h:589: error: (Each undeclared identifier is reported only once for each function it appears in.)

"configure" missing from HEAD?

Hi, I can't see "configure" in the HEAD in my fresh cvs checkout, nor the CVS browser on source-forge. How do I compile Gem without ./configure? Thanks B.
