along a geometry
The new expression functions are:
- triangular_wave: Constructs triangular waves along the boundary of a geometry.
- square_wave: Constructs square/rectangular waves along the boundary of a geometry
- wave: Constructs rounded (sine-like) waves along the boundary of a geometry
- triangular_wave_randomized: Constructs randomized triangular waves along the boundary of a geometry
- square_wave_randomized: Constructs randomized square/rectangular waves along the boundary of a geometry.
- wave_randomized: Constructs randomized curved (sine-like) waves along the boundary of a geometry
