Examples

This page showcases cubinterpp interpolation examples in one and two dimensions, covering different slope estimation methods and boundary conditions.

1 Dimension

The first example, available in main.py, compares linear interpolation against several cubic spline variants side by side, illustrating how the choice of slope estimation method affects the smoothness and accuracy of the result.

The second example demonstrates periodic boundary conditions applied to a parametric curve. The source code in periodic_spline.py shows how to configure a spline that smoothly closes on itself, making it well suited for cyclically repeating data.

Parametric curve with periodic boundary conditions

2 Dimensions

The following examples extend interpolation to two dimensions. Each plot shows the interpolated surface together with the input data points (red dots), making it easy to see how different methods handle the data. The full source is available in main_2d.py.

The final example applies periodic boundary conditions to a 2D parametric surface, producing a smooth, seamlessly tiling result. The corresponding source code can be found in periodic_spline_2d.py.
