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) ... ) >>> pl = pv.Plotter() >>> actor = pl.add_volume(grid, show_scalar_bar=False) >>> lut = actor.mapper.lookup_table >>> lut.cmap = 'bwr' >>> lut.apply_opacity([1.0, 0.0, 0.0, 0.3, 0.0, 0.0, 0.0, 0.3]) >>> pl.show()
