sheet

Generate a 3D surface from a Python function. This is a PythonSCAD-only function that creates parametric surfaces.

Syntax:

Python

sheet(func, imin, imax, jmin, jmax, fs=1.0, iclose=False, jclose=False)

Parameters:

Parameter	Type	Default	Description
func	callable	—	A Python function f(i, j) -> [x, y, z] that maps parameter values to 3D coordinates
imin	float	—	Minimum value of the first parameter
imax	float	—	Maximum value of the first parameter
jmin	float	—	Minimum value of the second parameter
jmax	float	—	Maximum value of the second parameter
fs	float	1.0	Step size for sampling
iclose	bool	False	Close the surface along the i parameter
jclose	bool	False	Close the surface along the j parameter

Examples:

Python

from openscad import *
from math import sin, cos, pi

def torus(i, j):
    R, r = 10, 3
    x = (R + r * cos(j)) * cos(i)
    y = (R + r * cos(j)) * sin(i)
    z = r * sin(j)
    return [x, y, z]

sheet(torus, 0, 2*pi, 0, 2*pi, fs=0.3, iclose=True, jclose=True).show()
