for instance. We download the svn development sources...<br>
Please, it would be great to have the source of cube, for instance, or any<br>

there is no real documentation on how to do that.<br>
<br>
if you want to do it in C++, you should go for the sources.<br>
basically, each Gem-object has it's own file (living in different directories, depending on their "type").<br>
e.g. the code for [cube] can be found in Gem/src/Geos/cube.cpp (.h).<br>
<br>
to start a new object, it's probably easiest to just copy an existing object:<br>
- copy<br>
$ cp Geos/cube.cpp Geos/supercube.cpp<br>
$ cp Geos/cube.h Geos/supercube.h<br>
- rename the object's internals<br>
$ sed -e 's|cube|supercube|g' -i Geos/supercube.cpp<br>
$ sed -e 's|cube|supercube|g' -i Geos/supercube.h<br>
- recompile<br>
$ make<br>
- use<br>
[supercube]<br>
<br>
the above is a bit simplistic, you will probably want to do the search&replace manually, rather than trusting sed;<br>
obviously, you also might want to add some code before running make.<br>
<br>
<br>
<br>
however, there you don't necessarily need to write C++ code.<br>
for simple things, Gem wraps all the openGL commands into objects. e.g. you can use [GEMglVertex3f] rather than glVertex3f()<br>
<br>
for more complex things, you could use one of the scripting languages supported by Pd, e.g. lua (frank barknecht has done some nice things with Gem & lua; there might be examples in the web...)<br>
<br>
and of course there is GridFlow's openGL injector, that allows you to write openGL commands as messages, and inject them into Gem.<br>
something like (it's surely not working, but you should get the idea):<br>
