pyvista.plotting.volume_property.VolumeProperty.apply_lookup_table

VolumeProperty.apply_lookup_table(lookup_table: LookupTable)

Apply a lookup table to the volume property.

Applies both the color and opacity of the lookup table as transfer functions.

Parameters:

lookup_tablepyvista.LookupTable, optional

Lookup table to set the color and opacity transfer functions.

Examples

Plot perlin noise volumetrically using a custom lookup table.

>>> import pyvista as pv
>>> noise = pv.perlin_noise(1, (1, 3, 5), (0, 0, 0))
>>> grid = pv.sample_function(
...     noise, [0, 3.0, -0, 1.0, 0, 1.0], dim=(40, 40, 40)
... )
>>> grid['scalars'] -= grid['scalars'].min()
>>> grid['scalars'] *= 255 / grid['scalars'].max()
>>> pl = pv.Plotter()
>>> actor = pl.add_volume(grid, show_scalar_bar=False)
>>> lut = pv.LookupTable(cmap='bwr')
>>> lut.apply_opacity([1.0, 0.0, 0.0, 0.3, 0.0, 0.0, 0.0, 0.3])
>>> actor.prop.apply_lookup_table(lut)
>>> pl.show()
