Generate a surface covered with randomly placed hills.

ParametricRandomHills generates a surface covered with randomly placed hills. Hills will vary in shape and height since the presence of nearby hills will contribute to the shape and height of a given hill. An option is provided for placing hills on a regular grid on the surface. In this case the hills will all have the same shape and height.

Parameters:

numberofhillsint, default: 30: The number of hills.

Changed in version 0.43.0: The numberofhills parameter has been renamed to number_of_hills.
hillxvariancefloat, default: 2.5: The hill variance in the x-direction.

Changed in version 0.43.0: The hillxvariance parameter has been renamed to hill_x_variance.
hillyvariancefloat, default: 2.5: The hill variance in the y-direction.

Changed in version 0.43.0: The hillyvariance parameter has been renamed to hill_y_variance.
hillamplitudefloat, default: 2: The hill amplitude (height).

Changed in version 0.43.0: The hillamplitude parameter has been renamed to hill_amplitude.
randomseedint, default: 1: The Seed for the random number generator, a value of 1 will initialize the random number generator, a negative value will initialize it with the system time.

Changed in version 0.43.0: The randomseed parameter has been renamed to random_seed.
xvariancescalefactorfloat, default: 13: The scaling factor for the variance in the x-direction.

Changed in version 0.43.0: The xvariancescalefactor parameter has been renamed to x_variance_scale_factor.
yvariancescalefactorfloat, default: 13: The scaling factor for the variance in the y-direction.

Changed in version 0.43.0: The yvariancescalefactor parameter has been renamed to y_variance_scale_factor.
amplitudescalefactorfloat, default: 13: The scaling factor for the amplitude.

Changed in version 0.43.0: The amplitudescalefactor parameter has been renamed to amplitude_scale_factor.
number_of_hillsint, default: 30: The number of hills.
hill_x_variancefloat, default: 2.5: The hill variance in the x-direction.
hill_y_variancefloat, default: 2.5: The hill variance in the y-direction.
hill_amplitudefloat, default: 2: The hill amplitude (height).
random_seedint, default: 1: The Seed for the random number generator, a value of 1 will initialize the random number generator, a negative value will initialize it with the system time.
x_variance_scale_factorfloat, default: 13: The scaling factor for the variance in the x-direction.
y_variance_scale_factorfloat, default: 13: The scaling factor for the variance in the y-direction.
amplitude_scale_factorfloat, default: 13: The scaling factor for the amplitude.
**kwargsdict, optional: See surface_from_para() for additional keyword arguments.

Returns:

pyvista.PolyData: ParametricRandomHills surface.

Examples
