Create a 3D shape by spinning 2D image

Hi guys, I'm trying to create a 3D object in OpenGL by spinning an 2D image (as PNG) or a 2D matrix. So instead of having these concentric circles, I kind of want concentric spheres. I'm very experienced in max but not so much in jitter. Is there a way to achieve this?

I'm creating generic audio visualisations for 360 degree VR videos as shown in the following example:

check jit.gl.gridshape help file

here is spinning

circles in video example are not spinning

Thanks for your reply! But this is not really what i want. I do not want the spinning motion, but instead a solid body by rotating or spinning the 2D matrix. I kind of did the same by going from a 1D matrix, a line, to the circle by using jit.repos

Hi, Hannes.

I'm not sure I understand completely your goal, but here's an example in 3D using spheres.

My attempt at creating a 3D sphere from a 1D line, the line drawing the profile of the sphere, although I'm not sure either what you're looking for.
