Iso surface of ``` cos(x) + cos(y) + cos(z) ``` python code to generqte : ``` import numpy as np from skimage import measure from stl import mesh bound = np.pi * 4 samples = 50 padding = 2 r = np.linspace(start=-bound, stop=bound, num=samples) xx, yy, zz = np.meshgrid(r, r, r) voxel_grid = np.cos(xx) + np.cos(yy) + np.cos(zz) voxel_grid = np.pad(voxel_grid, padding, 'constant', constant_values=0) # Use marching cubes to obtain the surface mesh vertices, faces, normals, values = measure.marching_cubes(voxel_grid, level=0.0) maillage = mesh.Mesh(np.zeros(faces.shape[0], dtype=mesh.Mesh.dtype)) for i, f in enumerate(faces): for j in range(3): maillage.vectors[i][j] = vertices[f[j], :] maillage.save('cos 4x4x4.stl') ```
