You can specify two different types of shaders for each material:
The vertex shader runs first; it receives attributes, calculates / manipulates the position of each individual vertex, and passes additional data (varyings) to the fragment shader.
The fragment ( or pixel ) shader runs second; it sets the color of each individual "fragment" (pixel) rendered to the screen.
Noise
Noise is an indispensable tool for creative coding. We use it to generate all kinds of organic effects like clouds, landscapes and contours. Or to move and distort objects with a more lifelike behaviour.
