it is obviouslly a good choice for this task.
cheers

There is also the [gemvertexbuffer] object to draw a mesh.
See help and examples about it.

hello,
for now, i thik the most optimized solution is to :
use a tabdump extern to send the data to a pix_set object
use a shader to distord a mesh_square/mesh_line geometry according to
this texture
I have plan to add a message to pix_set object to read directlly the
table to remove the list bottleneck (and an external dependency)
I would also love to have time to include this functionality to
mesh_square...
But if you have only few thousand line to draw, [curve 2] object (with a
[res 2< message) and a loop will be fine on any recent computer.
(or GEMglBegin etc)

I have (large, e.g. size >512) quickly-varying arrays of data in Pd
that I'd like to turn into vertices/lines in GEM. How do I either
1) draw a large mesh (such as with jit.gl.mesh) without having to, for
example, specify a [polygon] with 512 inlets
or
2) send individual drawline commands to GEM (without having to, for
example, use GEMglBegin with 512 GEMglVertex3f objects in a row), e.g.
[drawline x y z x y z (
(the only other idea I have is to use a vertex shader and send in
lists of point data as a parameter to that, which hopefully doesn't
have a bottleneck)
thanks for any advice, Dan
