Volumes, also called volumetric data or voxel grids, are 3D spatial datasets structured as a grid of volumetric cells. Each voxel contains a data value, such as a geological property, geophysical measurement, or simulation result.

Importing Volumetric Data

Import volumes through the Data Import Wizard. See Import Formats for the currently supported volume formats and their availability.

Visualizing Volumes

The Volume Inspector provides controls for the colormap and displayed data range, threshold filtering, rendering, and independently positioned X, Y, and Z slices.

Volume interpolation can be set to Discrete, which displays raw voxel values with sharp boundaries, or Interpolated, which smooths transitions between values. Rendering options include Direct Volume Rendering, Isosurface, and Maximum Intensity.

The same volume displayed with Interpolated interpolation.

The same volume displayed with Interpolated interpolation.

The same volume displayed with Interpolated interpolation, smoothing the transitions between voxel values.

Volume slices can be enabled and positioned independently of the threshold applied to the 3D volume. This allows slices to remain visible while the volumetric representation is filtered or hidden.

Two active volume slices along the X and Y axes, with the Z slice inactive.

Two active volume slices along the X and Y axes. The 3D volume is hidden by inverting a threshold that covers the full data range.
