class pyqtgraph.opengl.GLVolumeItem(data, sliceDensity=1, smooth=True, glOptions='translucent', parentItem=None)[source]#

Bases: GLGraphicsItem

Displays volumetric data.

__init__(data, sliceDensity=1, smooth=True, glOptions='translucent', parentItem=None)[source]#

Arguments:

data

Volume data to be rendered. Must be 4D numpy array (x, y, z, RGBA) with dtype=ubyte.

sliceDensity

Density of slices to render through the volume. A value of 1 means one slice per voxel.
