Not sure how to efficiently go about this. jit.gl.sketch doesn’t seem to have an matrixoutput mode, and jit.gl.gridshape outputs circles which are filled in by more vertices, otherwise I could use that with [jit.gl.multiple @matrixoutput 1]

Any advice appreciated…

andrew benson posted a version of this which did the necessary matrix math to draw multiple circles with a single mesh.
