Hi,
I'm starting to use GEM, and now I'm able to draw a [square], a [circle], etc. and to rotate, translate and scale its.
But how can I draw a single point? (a white pixel)

Thanks,
t.

something like this:

[gemhead]
|
[GEMglBegin]\[glDefine GL_POINTS]\[loadbang]
|
[GEMglVertex3f]
|
[GEMglEnd]

for a more elaborate example, i just posted an IFS in Gem on the Pd list that draws many points at once -- http://lists.puredata.info/pipermail/pd-list/2008-08/064635.html

Your simple patch work well,
thanks!
