Perlin noise: This node creates a terrain using a Perlin noise
generator.
Ridged noise: This node creates a terrain using a Ridged noise
generator.
Billowy noise: This node creates a terrain using a Billowy
noise generator.
Cellular noise: This node samples points across the terrain
that act like mini-generator diffusing an elevation around them,
thus creating cell-like structures.
Constant elevation: This node creates flat ground, whose width,
height, quad size, and altitude are defined.
Slope: This node creates a terrain plane with an editable
inclination and orientation.
Half-sphere: This node creates a half-sphere or semi-ellipsoid
plot.
Cone:
This node creates a terrain in the form of circular cone.
