004544: Irregular Z spacing

Description

A voxel dataset is regularly gridded if the spacing between values is constant. For example, z-values are irregular if the spacing changes across the z-range, such as 0, 5, 50, 100. Values are regular if they are spaced at constant intervals such as 0, 5, 10, 15, 20. A voxel layer is able to account for irregular spacing in the Z dimension when exaggeration is applied. A multipatch feature class does not account for irregular spacing and the output will not match the visualization of the voxel layer even with the same exaggeration values applied.

Solution

No action is required if you accept that the output feature class will be visualized differently than the input voxel layer isosurfaces.

Use the Voxel Dataset Regularize Z Python Script or the Voxel Layer Regularize Z Toolbox to adjust the spacing in the voxel dataset.
