Add ability for linear cell extrusion to extrude on point normals
The Linear Cell Extrusion filter will extrude a 2d surface based on some variable. Please add the following two features.
- Ability to extrude based on object units, not a variable. See example below - we want to not depend on a variable such as object_id.
- Ability to extrude based on point normals, not cell normals. Again see example below.
Example.
- 5.12.0-RC1, MacOS, builtin server.
- Open disk_out_ref.exo. Apply.
- Extract Surface. Apply.
- Linear Cell Extrusion. As we want a variable with a 1 in it, select object_id. Scale factor 1. Apply.
What we want is the image below, with the ridge tops touching. I believe this can be done again by finding the cell normal (which is obviously being used for this filter), deriving the normals at the points, and extruding the serface along these point normals.
