DESC: App that shows you some zFunctions like senoid, raindrop, Perlin noise, in a 3D way but, really this is another excuse to play with Three.js.
HUMAN DESC: I did this for two reaons, learn about ThreeJS and share it with the community. I hope it will be usefull. Fell free to use it as a template and add your own zFunctions.
PD: still a lot of to learn.
