9.116. Remove Flagged Triangles
Group (Subgroup)
Surface Meshing (Misc)
Description
This Filter removes Triangles from the supplied Triangle Geometry that are flagged by a boolean mask array as true. A new reduced Geometry is created that contains all the remaining Triangles. It is unknown until run time how many Triangles will be removed from the Geometry. Therefore, this Filter requires that a new TriangleGeom be created to contain the reduced Triangle Geometry. This new Geometry will NOT contain copies of any Feature Attribute Matrix or Ensemble Attribute Matrix from the original Geometry. The mask is expected to be over the triangles themselves so it should be based on something from the Face Data Attribute Matrix.
Data Handling
For each of the vertex and edge data attribute matrices, the user can select to copy none, some or all of the associated data arrays into the newly created geometry. If the user wishes to not copy any of the data, just leave the choice to “Copy Selected XXX Data” [0] but do not populate the list with any selections.
Note: Since it cannot be known before run time how many Vertices will be removed, the new Triangle Geometry and all associated Triangle data to be copied will be initialized to have size 0.
Example Output
The next figure shows a triangle geometry that has had a mask generated. Yellow parts are flagged as true.
The next figure shows the result of running the filter.
