I;ve been trying to get this patch into matrix form so that I can record it with jit.vcr.. I have already checked out jitter tutorial 31 on rendering destinations for openGL and the jit.gl.render help patcher but no luck on this one. I was able to get the output that appears on jit.window into a pwindow like what is done in the tutorial 31 but not directly into the matrix. dunno where I am going wrong? :/

cant-get-patch-with-jit-gl-pix-and-jit-gl-videoplane-into-matrix

I would stay with texture and use syphon server + syphon recorder (

So is [jit.gl.asyncread] a more efficient way to convert OpenGL context content into a matrix? Is that it's purpose?

that is exactly its purpose. there are 3 ways to render gl output to a matrix

1 - set a named jit.matrix as the gl drawing destination

2 - send a jit.gl.texture (or a gl object's gl-texture output) through a jit.matrix

technique 1 uses software rendering, not generally recommended unless you have specific needs, 2 and 3 use glReadPixels. the asyncread help file describes its technique in more detail. 2 or 3 will be fine for most cases, but you should test them to figure out which is more efficient / better suited for your particular needs.

awesome. this thread was really helpful!


can't get patch with jit.gl.pix and jit.gl.videoplane into matrix
