<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>

I want to build this visual <a href="http://processing.org/learning/trig/" target="_blank">http://processing.org/<u></u>learning/trig/</a> in Pd, but I want the sine curve to be drawn dynamically with every circle spin. It seems quite hard though.<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>
