Godot 3.0 GPU 2D and 3D Simplex Noise 1.0

This is an example on how to use Simplex Noise, that is generated on GPU (and that is why it is extremely fast).

There are three scenes:

First one is 2d example which just shows Sprite with noise texture, generated by 2d noise shader.

Second on is 3d example that uses another shader, that has a 3d noise implementation and uses vertex shader to deform simple plane mesh.

Third (and main) example shows how to read values from the sprite node (which uses 2d noise shader) and use this data to modify y positions of objects on the scene.
