PyVista，如何保存整个呈现结果
PyVista，如何保存整个呈现结果
提问于 2021-01-15 01:10:21
当使用PyVista时，我们可以使用mesh.save()或mesh.save()来保存网格，但不能保存整个呈现结果。以下面的代码为例，如何保存呈现结果，而不是只保存一个网格？
from math import sin, cos, radians
import pyvista as pv
# Create source to ray trace
sphere = pv.Sphere(radius=0.85)
# Define a list of origin points and a list of direction vectors for each ray
vectors = [ [cos(radians(x)), sin(radians(x)), 0] for x in range(0, 360, 5)]
origins = [[0, 0, 0]] * len(vectors)
# Perform ray trace
points, ind_ray, ind_tri = sphere.multi_ray_trace(origins, vectors)
# Create geometry to represent ray trace
rays = [pv.Line(o, v) for o, v in zip(origins, vectors)]
intersections = pv.PolyData(points)
# Render the result
p = pv.Plotter()
p.add_mesh(sphere, show_edges=True, opacity=0.5, color="w", lighting=False, label="Test Mesh")
p.add_mesh(rays[0], color="blue", line_width=5, label="Ray Segments")
for ray in rays[1:]:
p.add_mesh(ray, color="blue", line_width=5)
p.add_mesh(intersections, color="maroon", point_size=25, label="Intersection Points")
p.show()回答 1

合并(grid=None，merge_points=True，inplace=False，main_has_priority=True)
Join one or many other grids to this grid.
Grid is updated in-place by default.
Can be used to merge points of adjacent cells when no grids are input.
Parameters
grid (vtk.UnstructuredGrid or list of vtk.UnstructuredGrids) – Grids to merge to this grid.样本：
mesh = py.PolyData()
obj = mesh.merge(grid_list)
