I believe the easiest solution is for you to create a field that contains the id of each point in the mesh. Then when you run Extract Surface
, the field of ids will be permuted appropriately. The easiest way to create ids for points (and cells) is to use the Generate Ids
filter.
So, to run Extract Surface
while preserving the initial point ids, do the following.
- Add the
Generate Ids
filter. Apply. - Add the
Extract Surface
filter. Apply.
The result of Extract Surface
will have a point id field containing the original point ids.
