10.162. Write Vtk Rectilinear Grid
Group (Subgroup)
I/O Filters
Description
This filter writes the selected data to a VTK legacy file. A VTK legacy file is the older, human-readable file format used by the Visualization Toolkit (VTK); it can be opened directly by common scientific visualization tools such as ParaView and VisIt.
The file is written with a dataset type of RECTILINEAR_GRID. A rectilinear grid stores three explicit per-axis coordinate arrays (one list of X positions, one of Y positions, and one of Z positions). The grid lines are axis-aligned but the spacing along each axis may vary.
Although the input to this filter is an Image Geometry (which has a single uniform spacing along each axis), the output is written in the rectilinear-grid form: the filter expands the image’s uniform spacing into the explicit per-axis coordinate arrays that the RECTILINEAR_GRID format requires. If the output only needs uniform spacing, the smaller Write Vtk Structured Points format may be preferable.
The user selects which Cell Data Arrays from the Image Geometry are written into the file. Each selected array becomes a cell-data field in the VTK file.
The Write Binary File parameter controls the on-disk encoding. When false (the default), the data is written as plain ASCII text, which is portable and easy to inspect but larger and slower to read. When true, the data is written in VTK’s binary form, producing smaller files that load faster.
Required Input Sources
Image Geometry – the geometry whose dimensions and spacing define the grid.
Cell Data Array(s) to write – any per-cell arrays on the Image Geometry. A common choice is a FeatureIds array produced by Segment Features (Scalar).
