Water drops on camera


Recommended Posts

You would need 2 cameras, a scene camera, & a drops camera which was ortho.

Why is there a need for a second camera? Couldn't be the drops on the default "FreeCamera"?

Is it possible to put a bump mapping in front of the camera with zero alpha and PBR? :unsure:

(I'm pretty new to Babylon.JS ;))

Hey man, you already answered your question take a plane an place it like a filter of a real world camera before your lens, then you can do anything you want with it, sprites, animate wrap UV, its cheap, quick and fast.
8 vertices, 1 texure, 2 lines of code.

Did it! It is actually much easier than I thought.

Just add following line:

var postProcess = new BABYLON.RefractionPostProcess("Refraction", "textures/normalMap.jpg", new BABYLON.Color3(1.0, 1.0, 1.0), 0.5, 0.5, 1.0, camera);

Result is here: http://babylonjs-playground.com/#FCRJG

I got this line from: http://www.babylonjs.com/Demos/PPRef/
