4. TVTK的数据集

1. VTK的数据集

2. ImageData

from tvtk.api import tvtkimg = tvtk.ImageData(spacing=(1,1,1),origin=(1,2,3),dimensions=(3,4,5))img.get_point(0)# Out[8]: (1.0, 2.0, 3.0)for n in range(6):    print("%.1f, %.1f, %.1f" % img.get_point(n))# 1.0, 2.0, 3.0# 2.0, 2.0, 3.0# 3.0, 2.0, 3.0# 1.0, 3.0, 3.0# 2.0, 3.0, 3.0# 3.0, 3.0, 3.0

3. RectilinearGri

需要指定每个格子的大小。

from tvtk.api import tvtkimport numpy as npx = np.array([0,3,9,15])y = np.array([0,1,5])z = np.array([0,2,3])r = tvtk.RectilinearGrid()r.x_coordinates = xr.y_coordinates = yr.z_coordinates = zr.dimensions = len(x),len(y),len(z)

4. StructuredGrid

5. Polydata
