Hi, I am implementing a Gaussian blur effect by alternating between a horizontal and a vertical blur shader (in the implementation they are the same shader, switching based on a uniform).
In OSG I managed to implement this by adding the two shaders to geometry nodes containing a screen sized quad and having the camera configured for rendering to a texture. To get the best looking effect I want to execute this pair of shaders several times in a single frame. I can of course add the pair of nodes to the scene graph multiple times, but there must be a more elegant solution: Is there some kind of "repeater" node which simple executes its subtree multiple times? If not, how would I implement such a node? Should I write a new traverse method? How to handle the different kinds of visitors? Thank you!
