Sorry, meant Pd-extended...

It's a bit strange but Pd can't create [GEMglVertex] or
[gemvertexbuffer]. In the browser I found [gemframebuffer] but not the vertex one. [GEMglBegin] and [GEMglEnd] are being created, no prob. I'm using the latest Pd...
lattest pd will not help. you need Gem for all of this. since GEMglBegin works, you certainly have one version of Gem. since gemvertexbuffer did not create, your version of Gem too old. according to gem website, the last release is 93.3, from 11/11/2011. that's the explanation.

hello, you have lot's of solution to draw a sinus curve in Gem. the easiest would be to use scopeXYZ, but you'll have to do the sinin audio signal.
the most efficient is to use gemvertexbuffer to draw a line betweenpoints specified in table.
the fastest to code is to use repeat/separator/curve 2 in order todraw many lines
you can also do like in openGL : using GEMglBegin, GEMglVextex (manyof them thanks to an iterative loop), and GEMglEnd
you can also do that in shader, but that would be to much complexityfor this.
and you can certainly find other way to do that, but i think i coverthe most used. cheers c

It seems quite hard though.
I don't know which object would be best. I tried either [curve]but the parameters are way too many and I'm not sure if precision is really possible. Then I tried [square 0.008] in combination with [repeat] but also doesn't work. Anyone knows how to do this?
