[sharing is bladibla] Render multiple views of 1 GL scene for Triplehead setup

There’s many multiple view rendering methods and examples on the forum but I didn’t find a complete example of this one yet. Thought I’d post it for ya’ll…

It renders 3 different camera perspectives of a scene (a particle system in this case) to one large 2400×600 window which is meant for a Triplehead output. The window has 3 800×600 videoplanes spread over it. Each camera view is rendered to its own videoplane (= monitor out) using to_texture.

This isn’t optimized for frame rate yet. There’s obvious fps increases and decreases depending on which windows are visible on which monitor.

Comments and improvements appreciated.

It looks like this setup performs best when both windows are on the Triplehead output, the small one hidden behind the large one.

Is there a way to get rid of the small one altogether? Making it visible 0 stops the rendering.
