[PD] GEM : How to create vertex dynamically? / drawing 3D lines?

I would like to be able to draw lines
in a 3D space with a Wacom pen tablet,
and I cannot find any solution for creating
I had managed to do that with Jitter
quite simply with the sketch object
and commands "moveto" "lineto".
But it seems that there is no way to
dynamically add new vertex and link them to
get a line (bezier or even a simple).
I thought I could it with VertexArrays
but the function handling pointers
are not (?) accessible in GEM.
is instanciated correctly but
glVertexPointer(GLint size, (...), const GLvoid
If this is actually implemented, are there
any reference guide for how one should type
the names and command?
Something like GLdefine for pointers?
I guess dynamically instanciating new
[GEMglVertex3f] objects every time I get
a message from the tablet is not the solution.
(Well, I hope too ;-)
The operation seems quite common though...
I guess that some people must have done
similar stuff, if the GEMtablet exists...
Did I miss a sooooo simple function/command?
Are there any objects/patchs already doin this?
Any patch repository for GEM could be nice...
Last: since I would like to be able to deform
these lines after drawing them, maybe
my solution is not the best... (and sure isn't
at the present time)
Thanks for any helpful advice!
(still RTFM and STFW for now)
