Genuary 15: Sand

This is a sketch for Genuary 2022, which provides a creative coding prompt for each day of January. This is day 15: "Sand."

This works by generating a 3D Bézier path representing the top of the dunes. Each point is extended out to either side following an easing curve down to a height of 0. The surface is meshed and saved to a p5.Geometry for efficiency.
