pyvista.plotting.volume_property.VolumeProperty.interpolation_type

property VolumeProperty.interpolation_type: str

補間の種類を返すか設定します．

値は 'linear' または 'nearest' のどちらかでなければなりません．

例

サンプルの pyvista.ImageData データセットを作成します．

>>> import numpy as np
>>> import pyvista as pv
>>> n = 21
>>> c = -(n - 1) / 2
>>> vol = pv.ImageData(dimensions=(n, n, n), origin=(c, c, c))
>>> scalars = np.linalg.norm(vol.points, axis=1)
>>> scalars *= 255 / scalars.max()
>>> vol['scalars'] = scalars

最近接 (デフォルト) 補間のデモを行います．

>>> pl = pv.Plotter()
>>> actor = pl.add_volume(
...     vol,
...     show_scalar_bar=False,
...     opacity=[0.3, 0.0, 0.05, 0.0, 0.0, 0.0, 1.0, 0.0],
...     cmap='plasma',
... )
>>> actor.prop.interpolation_type = 'nearest'
>>> pl.show()

線形補間をデモします．

>>> pl = pv.Plotter()
>>> actor = pl.add_volume(
...     vol,
...     show_scalar_bar=False,
...     opacity=[0.3, 0.0, 0.05, 0.0, 0.0, 0.0, 1.0, 0.0],
...     cmap='plasma',
... )
>>> actor.prop.interpolation_type = 'linear'
>>> pl.show()
