パラメトリックジオメトリオブジェクト

パラメトリックオブジェクトを作成する

from math import pi

import pyvista as pv

この例では，pyvistaを使用してパラメトリックオブジェクトをプロットする方法を示します．

    (21.9930, 21.1810, -30.3780),
    (-1.1640, -1.3098, -0.1061),
    (0.8498, -0.2515, 0.4631),
]


# half ellipsoid

円弧

pointa = [-1, 0, 0]
pointb = [0, 1, 0]
center = [0, 0, 0]
resolution = 100

arc = pv.CircularArc(pointa, pointb, center, resolution)

pl = pv.Plotter()
pl.add_mesh(arc, color='k', line_width=4)
pl.show_bounds()
pl.view_xy()
pl.show()
