nipy.labs.datasets.volumes.volume_field.VolumeField.values_in_world

VolumeField.values_in_world(x, y, z, interpolation=None)

Return the values of the data at the world-space positions given by x, y, z

Parameters:

xnumber or ndarray

x positions in world space, in other words millimeters

ynumber or ndarray

y positions in world space, in other words millimeters. The shape of y should match the shape of x

znumber or ndarray

z positions in world space, in other words millimeters. The shape of z should match the shape of x

interpolationNone, ‘continuous’ or ‘nearest’, optional

Interpolation type used when calculating values in different word spaces. If None, the image’s interpolation logic is used.

Returns:

valuesnumber or ndarray

Data values interpolated at the given world position. This is a number or an ndarray, depending on the shape of the input coordinate.
