How can I implement a progressive AA post-process effect when the scene is idle?

[BlackMojito]

I am just curious if it is possible to implement such a thing just like all the ray-tracer does. Can someone give me any suggestion?

You mean progressive enhancement (which is not really applicable with a forward engine like babylon.js) or improved anti-aliasing?

For the latter, it is easy to detect that camera is not moving and then you can turn on FXAA or MSAA (see https://www.babylonjs-playground.com/frame.html#Y3C0HQ#146) and also improve the resolution (with http://doc.babylonjs.com/api/classes/babylon.engine#sethardwarescalinglevel)

I have already FXAA always on though...hum...can MSAA be turned on/off dynamically? I think we might need to recreated all the render targets which is ...quite heavy, right?

Here is my answer to a similar topic. Maybe it helps:

MSAA can be turned on / off dynamically (like in the default rendering pipeline)

OK! I will try it!
