Windows and MacIntel binaries
by chris clepper 09 Jan '07

09 Jan '07

I have a Windows and Intel Mac build of GEM that I believe are up to date and reasonably full featured. The only thing I could not get running on Windows is the fiducial tracking and the Pbuffer based code. I would like to post the binaries somewhere like IEM if possible. cgc

ArToolkitPlus -> Pure Data - Gem
by patrick 14 Nov '06

14 Nov '06

hi all, davide morelli did almost a working bridge of artoolkitplus and pure data - gem. i think it would bring many new possibilities to AR like opengl dataflow, sound, sensors, open sound control, video, physical modeling, importation of model (.obj) etc... please have a look at this url: http://www.davidemorelli.it/dokuwiki/doku.php?id=ar:augmented_reality_and_i… right now, the external is detecting the correct id of the marker and also follows each marker if we rotate it until the angle is below 90Â°... that would be fantastic if we can do this bridge. i cc artoolkit forum, many some people would be willing to help. pat

GemPixConvertAltivec...
by IOhannes m zmoelnig 31 Oct '06

31 Oct '06

hi. inspired by the changes jamie has done to GemPixConvertAltivec over the weekend, i have done some more (since jamie's changes only fixed _part_ of the errors we get on the 10.3 build machine). naturally i haven't done any testings, apart from looking whether it compiles fine on my machines. the change is in GemPixConvertAltivec:669 ( in YUV422_to_BGRA_altivec() ), where i changed the type from (vector signed int) to (vector unsigned int) this might have weird side effects, or might as well not. i am pretty sure, that there are still some more type errors - let's wait for tomorrow's autobuild log.... mfg.adsr IOhannes PS: oh, and i finally found a solution for the weird "\p" character warning in GemWinCreateMac: add "-fpascal-strings" to the CXXFLAGS.

anybody knows, why alitvec fails to compile on os-x 10.3? is this an issue of an outdated gcc? mfg.asdr.

[separator]
by Mathieu Bouchard 25 Oct '06

25 Oct '06

How do i get [separator] to separate colours? I was teaching the use of [separator] in a workshop and then I realised that it doesn't backup colours. Is [separator] really only for transformation matrices or is there an option to enable it to work with [colorRGB] and [alpha] and etc? _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard - tél:+1.514.383.3801 - http://artengine.ca/matju | Freelance Digital Arts Engineer, Montréal QC Canada

multiple windows
by Mathieu Bouchard 24 Oct '06

24 Oct '06

BTW, a question that was asked to me several times in the last few days is whether it's possible to have several independent [gemwin] and I really mean several windows. IIRC this was implemented some time ago but I don't remember reading on how to enable it. (I'm asking this is in part because I've been teaching quite a bit of Pd+GEM last weekend... 10 students, 10 hours) _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard - tél:+1.514.383.3801 - http://artengine.ca/matju | Freelance Digital Arts Engineer, Montréal QC Canada

bug in makefile
by Mathieu Bouchard 19 Oct '06

19 Oct '06

if the "make" command causes "./configure" to be called (presumably because it has just been regenerated), it does not reuse the options that ./configure was last called with. For example, I did this: ./configure --prefix=$HOME make make install and then it wanted to install in /usr/local because "make" reran "./configure" without any options. _ _ __ ___ _____ ________ _____________ _____________________ ... | Mathieu Bouchard - tél:+1.514.383.3801 - http://artengine.ca/matju | Freelance Digital Arts Engineer, Montréal QC Canada

Crashes with Matrox card

Hi, I'm getting strange crashes since I updated my xorg to the latest packages in Debian testing. The main error reported in gdb is this: pd: ../../../../../src/mesa/tnl_dd/t_dd_vb.c:298: mga_interp_extras: Assertion `VB->ColorPtr[1]->stride == 4 * sizeof(GLfloat)' failed.

This is with Chris McCormick's Ergates patch (http://mccormick.cx/projects/ergates/) however I've seens this happen with other patches as well, however I couldn't really nail it so far to a single object. Gem is current CVS from today, compiled with "--disable-NV", otherwise defaults. I also get the same error with an older version of Gem-CVS, like some weeks ago. My card is a Matrox G450. Any ideas?
