Here is the MingW docs for how to do that but the link to reimp
appears to be dead.
http://www.mingw.org/wiki/MSVC_and_MinGW_DLLs
If you could reverse engineer this it might work. Appears the stack is
reversed and the segments are in diferent chunks.

Indeed the GEM exports are declared like this
# define GEM_EXPORT __declspec(dllexport)
The thing to do is use vc++ to compile to assembly language an export function.
Then get gcc to compile the corresponding import function.
Look at the differences and make some inline assembly code to compensate.
Here is a reference from the gcc vcc+ veiwpoint.

Hopefully the compiler understood.
I have also used the quaternion with W removed.
Here are my notes on the matter.

A*B=C

A:[x1,y1,z1]
B:[x2,y2,z2]
C:[x,y,z]
[x1,y1,z1] * [x2,y2,z2] = [x,y,z]
x = (x1*x2) - (y1*y2) - (z1*z2)
y = (x1*y2) + (y1*x2)
z = (x1*z2) + (z1*x2)

Having merged this feature (with changes) to pd-l2ork, I can attest that the patch in its current condition will not work because memory allocation has changed dramatically since the patch was submitted, rendering it incomplete (e.g. code won't even compile). If interested, feel free to dig around pd-l2ork code to find the updated implementation (sans $# which is superfluous with the introduction of [list length], as Jonathan pointed out).

[PD] [PD-announce] Tamuke - Offerings for Japan - Montreal
Please forgive x-posts. 手向け TAMUKE Offrandes pour le Japon / Offerings for Japan April 1, 2011 from 8PM to 3AM SAT, 1201, Boulevard Saint-Laurent Open Call to all Laptop/iPhone Musicians in Montréal Bring Your Own Laptop Orchestra matralab (Hexagram Concordia) in collaboration with the SAT (Société des arts technologiques) is organizing an artistic response to the disasters in Japan (see the website for more info http://matralab.hexagram.ca/tamuke/). The event will take place this friday at the SAT, 1201, Boulevard Saint-Laurent in Montréal. Around midnight we would open the stage for all Laptop/iPhone musicians to come together and create a collective sound work, led and inspired by Eldad Tsabary, founder and director of the Concordia Laptop Orkestra (CLOrk). Over the past weeks, matralab (Concordia University) has collected some news audio footage from the disasters with the goal of creating an audiowave representing the mayhem that occurred when the tsunami hit Japan. We invite you to bring your laptop/iPhone and your own portable speakers/amplifiers ! Come latest at 11pm. At the SAT, you will be able to download the audio files of the disaster from a local server. Everyone is welcome to interpret, mashup, remix, livecode, or play back those materials with their software of preference. We would prefer if you used MAINLY these materials. At 11:45pm, Eldad Tsabary will give a short and simple intro into his laptop conducting technique, so that the sounds coming from all of you can be coordinated in some way by visual signs. At midnight, you will all go to the stage and perform together for 30 min. Please feel free to forward this announcement to anyone who may be interested. And come yourself, of course. And please sign-up by e-mail to japan.vi...@gmail.com just so we can estimate how large the BYOLaptop Orchestra will be. -- Michal Seta Tech coordination TAMUKE Project 514.575.9243 ___ Pd-announce mailing list pd-annou...@iem.at http://lists.puredata.info/listinfo/pd-announce ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

[PD] Gem Stereo Imaging
Hi List I have a question concerning the Stereo Imaging capabilities in Gem. In two weeks I do the visuals on a party and I've written a patch with some animations. The idea was to do those projections in a simple form of 3d-Vision as a little gimmick, nothing too fancy though. My question is: Does anyone of you have expierience with this? More importantly is there a way to project the visuals in red/cyan? That's what the 3d-Glasses merchant told me would work best. I only found a red/green stereo mode in pure data, which he told me would only work with black and white animations.
