Volumes, also referred to as volumetric data or voxel grids, represent 3D spatial datasets structured as a grid of volumetric cells (voxels). Each voxel contains a data value, such as geological properties, geophysical measurements, or simulation results, making this data type essential for subsurface modeling, resource estimation, and scientific visualization.

Importing Volumetric Data

• Supported formats include CSV and VTK. See Import Formats for all currently supported formats.
• Volumes are imported via the Data Import Wizard.

Volume-Specific Features & Visualization

For features specific to volumes, please see the Volume Inspector. These include various 3D visualization controls, such as threshold-based data filtering, different rendering modes, and volume slicing in X, Y, and Z directions.

Use Cases

Volumetric data is widely used for:

• Geological modeling – Representing subsurface rock properties and structures.
• Mineral resource estimation – Visualizing ore deposit distributions.
• Geophysical data interpretation – Analyzing resistivity, density, or seismic attributes.
• Hydrogeology – Mapping groundwater flow and reservoir properties.

Point-based rendering of a volume.

Trilinear rendering of a volume.

Example of two active volume slices along the X and Y axes, with the Z-slice inactive. The 3D volume representation is hidden using “Invert Threshold” on a threshold covering the full data range.
