Surface Plots

3D surface visualizations of test functions.

Basic Surface Plot

import os
from surfaces.test_functions.algebraic import AckleyFunction
from surfaces._visualize import plot_surface

func = AckleyFunction()

# Create 3D surface plot
fig = plot_surface(func, title="Ackley Function")

if not os.environ.get("SURFACES_TESTING"):
    fig.show()

---

Customizing the Plot

import os
from surfaces.test_functions.algebraic import RastriginFunction
from surfaces._visualize import plot_surface

func = RastriginFunction(n_dim=2)

fig = plot_surface(
    func,
    title="Rastrigin Function",
    resolution=100,  # Grid resolution
)

if not os.environ.get("SURFACES_TESTING"):
    fig.show()

Saving Plots

import os
from surfaces.test_functions.algebraic import HimmelblausFunction
from surfaces._visualize import plot_surface

func = HimmelblausFunction()
fig = plot_surface(func)

# Save as interactive HTML (always works)
# fig.write_html("himmelblau_surface.html")

print("Plot created successfully!")

Multiple Functions

import os
from surfaces.test_functions.algebraic import (
    SphereFunction,
    RastriginFunction,
    AckleyFunction,
    RosenbrockFunction,
)
from surfaces._visualize import plot_surface

functions = [
    SphereFunction(n_dim=2),
    RastriginFunction(n_dim=2),
    AckleyFunction(),
    RosenbrockFunction(n_dim=2),
]

for func in functions:
    name = func.__class__.__name__
    fig = plot_surface(func, title=name)
    print(f"Created plot for {name}")
