Hello,<br>
<br>
I made an abstraction that draws in opengl directly from tables.<br>
just draw your sin in the y tables, and the x position in your x
table. see help patch,<br>
<br>
Best,<br>

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.<br>
I'm using the latest Pd...<br>
</blockquote>
</div>
lattest pd will not help. you need Gem for all of this.<br>
since GEMglBegin works, you certainly have one version of
Gem.<br>
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.<br>
<br>

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

in Pd, but I want the sine curve to be drawn dynamically
with every circle spin. It seems quite hard though.
<div class="im"> <br>
<br>
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.<br>
Anyone knows how to do this?<br>

Hello Alexandros,<br>
<br>
Do you have the current Pd-extended (which is 0.43.4) ? You should
have a recent Gem whit it.<br>
For glVertex, you have to write [GEMglVertex3f] to use float.<br>
