Yet another night vision shader

Hi,

I am relatively new to shader and I made as my first shader a night vision shader. I know there are many out there but for learning I wanted to do my own. I wanted to be as real as possible and took the following references:

Here are some pics:


Features:
- Ramp texture for colorisation
- Noise
- Lens distortion (for zoom effect or similar - third image)
- Blur
- Vignette
- Downsampling

Tested in Unity Editor with DX11, DX 9 and OpenGL

The sources with a sample project (first image) are here: https://bitbucket.org/Wompipomp/night-vision-shader
Asset package: https://drive.google.com/uc?export=download&id=0B2g4w3wcuDg_aVBmWEVsRUdEdTg

As I said I am new to shader so any feedback, optimisation tips etc. are very welcome

Thank you very much
Best regards
Mark

 

Looks great!

 

Thank you
