VTK STRUCTURED_POINTS Importer¶
This Filter reads a STRUCTURED_POINTS type of 3D array from a legacy .vtk file. A STRUCTURED_POINTS file is a more general type of Image Geometry where data can be stored at the vertices of each voxel. The currently supported VTK dataset attribute types are SCALARS and VECTORS. Other dataset attributes will not be read correctly and may cause issues when running the Filter. The VTK data must be POINT_DATA and/or CELL_DATA and can be either binary or ASCII. The Filter will create a new Data Container with an Image geometry for each of the types of data (i.e., POINT_DATA and/or CELL_DATA) selected to be read, along with a Cell Attribute Matrix to hold the imported data.
Note: In a STRUCTURED_POINTS file, POINT_DATA lies on the vertices of each unit element voxel (i.e., eight values per voxel), while CELL_DATA lies at the voxel center. This Filter will import both types of data as Image Geometries, since either form a structured rectilinear grid. This is to enable easier visualization of the POINT_DATA, and to enable greater flexibility when using DREAM.3D analysis tools, many of which rely on an Image Geometry.
