is there a way to convert open gl data to apply quicktime fx?

converting-opengl

found this example patch, it converts the opengl to a matrix, hope this what your looking for

yes, thanks a lot!! this is exactly for what i'm looking for.

A more efficient and easier way to convert back to matrix is using the

jit.gl.asyncread object available in jitter 1.7.

but when i use the "@visible 0" argument to the first jit.window everything stops. how can i hide this unnessesary window?

great! thanks a lot.

I'm not sure that you can get rid of a window for a particular context. I

think you always need one in order to set up the context for openGL. One

thing you can do is to have a 'preview' pwindow in your patch in place of

At this point, there's no way to use jit.gl.asyncread without a

visible window. This may be possible in a future version, but such a

change won't happen until the next major jitter update.

It works for me if I make sure that the window is visible for the first render cycle, and then set to @visible 0. This solution also works with the glreadpixels command to sketch - which I posted about a while back here:

Here's a Max5 example patch with gl.asyncread:
