10.144. Slice Triangle Geometry
Group (Subgroup)
Sampling (Geometry)
Description
This Filter slices an input Triangle Geometry, producing an Edge Geometry. The user can control the range over which to slice (either the entire range of the geometry or a specified subregion), and the spacing between slices. Currently this filter only supports slicing along the direction of the z axis. The total area and perimeter of each slice is also computed and stored as an attribute on each created slice.
Both the Slice Spacing and the User Defined Range values are specified in the same physical units as the input Triangle Geometry coordinates (for example, microns if the mesh is in microns). The computed slice area and perimeter are likewise reported in those physical units (squared, for area).
Additionally, if the input Triangle Geometry is labeled with an identifier array (such as different regions or features), the user may select this array and the resulting edges will inherit these identifiers.
Example Output
Example Surface Mesh being sliced with a 0.25 slice spacing.
Example Surface Mesh being sliced with a 2.0 slice spacing.
Slice Range
The Slice Range parameter controls which portion of the geometry is sliced:
Full Range [0]: Slices across the entire extent of the geometry along the slicing direction.
User Defined Range [1]: Allows specifying custom start and end values (in the geometry’s physical units) for the slicing range, restricting slices to a subregion of the geometry.
Required Input Sources
Triangle Geometry – an existing surface mesh. Typically produced by Create Surface Mesh (QuickMesh), read from disk via Read STL File, or assembled from multiple files by Combine STL Files.
