Grid Info Node

The Grid Info node retrieves structural and metadata information about a voxel grid. It provides details such as the grid’s spatial transform and background value, which describe how the grid is positioned in space and what value is stored in inactive (empty) voxels.

This node is useful for inspecting or reusing grid parameters in other grid operations, such as aligning transforms, matching resolutions, or reconstructing fields with consistent background values.

Inputs

Grid

The input voxel grid to query information from.

Properties

Data Type

The type of data stored in the grid (e.g. Float, Integer, Boolean, or Vector). Determines both the expected data type of the Grid input and the type of the Background Value output.

Outputs

Transform

The transform matrix that converts from grid index space to object space. Defines how the grid’s voxels are positioned, scaled, and oriented in 3D space. This can be passed to nodes such as Set Grid Transform or used to align other grids or geometry.

Background Value

The value assigned to inactive voxels in the grid. This represents the default or “empty” value used when sampling outside of active regions, as set by the Set Grid Background node or similar operations.
