This seems like a simple question, but I cannot figure out how to create a circular mask using jit.gl.gridshape that will not change the dimensions of the incoming video.
What I would like to do is take a live video signal and simply "open up" a circle that will allow a specific portion of the video to be viewed. My current patch (which is mostly from the jit.gl.gridshape help file) changes the dimensions of the video to conform to the circular shape. I have posted the patch below. There are many loadbangs, so please save it and then re-open it.
I would like to be able to change the values to [pak scale] (which is highlighted in green in the patch) and be able to see more or less of the incoming video, without distorting the dimensions.
Any tips would be appreciated.
