Bicubic Interpolation for Carpet Plots

Does anybody know for sure if the carpet plots use bicubic interpolation to create the carpet lines?


Here are the plotly.js files related to the carpet trace type: https://github.com/plotly/plotly.js/tree/master/src/traces/carpet (the files whose name starts with calc contain details on a carpet elements).

The interpolation method is the Centripetal Catmul-Rom spline interpolation.

Thanks very much empet! I will read through this documentation.
