A surface shader based on ShaderX1

Bubble Shader

A Unity implementation of the Bubble Shader paper found in the book

ShaderX : Vertex and Pixel Shader Tips and Tricks.

You can find the original paper inside the repo.

I should have all the other papers in another repository. They're great, you should take a look. EDIT: none are up yet

Cubemaps and rainbow map were extracted from the PDF. Using legacy cubemaps for the time being. Feel free to make a texture out of it.

Usage

This repo includes a surface shader that mimics the effect of a Soap Bubble.

To use it, apply it to a sphere or whatever mesh you want.

You can play around with the Fresnel settings in order to achieve the best look for your bubbles. eheh

Issues

Currently, there's a weird problem with Fresnel Term calculation, most likely because of the arrangement of the normals of the sphere.

Will have to try with a different mesh when i have the time.

But hey, it works fine if you only view it from a certain angle!
