mymesh.implicit.lidinoid

mymesh.implicit.lidinoid(x, y, z)

Implicit function approximation of the lidinoid triply periodic minimal surface (TPMS). This function uses sympy functions (sp.cos, sp.sin) to enable symbolic differentiation.

For efficient vectorized evaluation, use: x, y, z = sp.symbols(‘x y z’, real=True) vector_func = sp.lambdify((x, y, z), func(x,y,z), ‘numpy’)

Parameters:

• x (scalar or np.ndarray) – x coordinate(s)

• y (scalar or np.ndarray) – y coordinate(s)

• z (scalar or np.ndarray) – z coordinate(s)

Returns:

f – implicit function evaluated with sympy

Return type:

sympy expression

Examples

surface = implicit.SurfaceMesh(implicit.lidinoid, [0,1,0,1,0,1], 0.05)
surface.plot(bgcolor='w')
