this must be documented somewhere, but i can't locate it. is there some logic to the size units for GEM objects? like: what exactly is "2" in [cube 2]? thankyou jon
This is what you want or what you need. If you are working on a scene which represents a city then the units could be kilometers but if it represents a electronic circuit then the units could be millimeters. So, you decide. ++

i frankly never understood it, why a gem is not [0..1]x[0..1], a big mystery to me...
does it have to do with cabalistic practices? the [-4.4...4.4]x[-2...2] or is it?

# 2ème WORKSHOP PURE DATA @ DATABAZ [Angoulême]
Formateur : Philippe Boisnard Participants minimums : 5 / maximum : 12.
[+] Le workshop [pure data] est ouvert à tous :
data.
[+] Il s'agira tout au long de ce week-end d'immersion d'apprendre les
bases de la programmation
pure-data (video et audio) permettant de s'engager dans la création
d'un programme d'interactivité
(console de mixage audio/video / interaction avec Wii ou avec capteurs).
Le travail conjuguera une découverte des bases de la programmation et
une exploration de patches
(programmes) créés pour l'occasion, permettant de développer plus
rapidement les projets des
participants.
Il sera nécessaire d'amener un micro-ordinateur portable (MAC/PC/ LINUX) sur lequel sera installé [pure-data] et les librairies nécessaires pour le workshop.
Niveau confirmé :
[+] Approfondissement de la gestion des variables [au niveau des
messages, des objets, des subpatches et des abstracts].
[+] Un niveau confirmé sera développé par rapport à la gestion des
sauvegardes sous pure-data [textfile] [qlist] [coll].
[+] Les repas seront fournis par l'association Trame Ouest et pris
dans le centre Databaz.
[+] Possibilité pour ceux qui viennent de loin de dormir sur place :
réservation obligatoire : places limitées.
[+] Participations : _ [non adhérent] 60 € pour les deux jours (repas offert) _ [adhérent] 40 € pour les deux jours (repas offert) _ [étudiants, chômeurs, RMI/RSA] 40 € (repas offert)

I suppose it is influenced by the égalité idea of French revolution that no single direction should get a higher status than other directions. Everything is equal at the origin, then grows in all directions equally unless external influences change that.

It's twice as much as 1.
As Hannah Montana (or Talk Talk for the older ones among us) sang: Life's What You Make It! Gem doesn't have any real life units, it's just numbers.

In fact, if you don't change the gemwin's "view" parameters , z = 4.
So if you create a 512 * 512 dimensions window for example, and if you want to build a square with te same dimensions, your square's size will be 4.
Il you create a 600 * 400 dimensions window, the size of corresponding rectangle will be 6 * 4.
Is this what you wanted to know?

i was just curious, since it's obviously not pixels or anything else that i could understand... i'll stick to the hannah montana/talk talk motto then. thank you all
A rectangle at position 0 0 0 with rotation 0 0 0 with height 4 exactly fits the screen height. So yes, there is actually a refernce: the screen height.

Most Gem objects are wrappers to OpenGL commands.
While pd-list is indeed full of helpful fellows, I would suggest looking into documents on OpenGL for facts and design concepts unclear through reading only ones installed with Gem.
i.e., as I see from searching, your question may be new to this list but appears to be an FAQ in the OpenGL field.
Although I do not recommend it, flipping through the first 4 chapters of the "OpenGL programming guide" http://www.opengl.org/documentation/red_book/ even if you are not specifically a C programmer.
It helped me catch up with sooo many WHYs of Gem which had me puzzled for years.
So GEM units are QuarterWindowSides, then?

4/4 = 1, yes.
It works for X and Y if your screen is a square.
If you create a 400 * 600 screen you will get a 2.67 * 4 rectangle If you create a 600 * 400 screen you will get a 6 * 4 rectangle

don't care about the unit, use the perspec message to set it to whatever you want/need. c
