# Risograph grain effect in Three.js

Learn two ways of applying a creative grain effect to 3D elements in Three.js.

[Demo 1](http://tympanus.net/Tutorials/RisographGrainShader/)

[Demo 2](http://tympanus.net/Tutorials/RisographGrainShader/index2.html)

The demos show two ways of creating a risograph 2D grain effect reacting to light reflection on 3D objects using Three.js. The first way is using a custom shader (fragment and vertex). The second way is reusing the MeshLambertMaterial shader and applies 2D grain effect on the fragment shader, it's also using a transparent effect.

## Installation
