I am working on a patch (attached) which is for doing titles using OpenGL. It was easy enough to use jit.gl.text2d to create titles over video planes. I then decided that I wanted to do a blur/fade for every line of text, and used a jit.gl.node to capture the 2D text to a texture and then slabs to blur and fade. Works fine.
The problem is that I then have my text on a videoplane which obscures the video on the videoplane behind it. I can use another slab to key that out and get titles with blur over video, but is there a better way to do this?
Is there another way to blur the text2D objects as-is without capturing to a texture and then using a slab (and then keying the rest of the video plane?)
Alternatively, is there a better method for displaying the resulting texture over the video behind , having just the text showing?
