Rain drops on screen
- by user1075940
I am trying to make simple rain drop effect on screen.Something like this

My idea is to:
Create small drop shaped normal textures,randomly put few on screen,apply texture perturbation and mix with current frame pixels.
Here are my questions:
-Does this idea even have sense?How professionals do this effect?Everything from text to code will be appreciated
-How to pass pixels to shader of already rendered frame?
