displaying model edges only
Is your feature request related to a problem? Please describe. currently option to displaying mesh files (STL, VTK, etc) are for edge mesh i.e based on each of element mesh.
when hidden edge mesh is de/active by 'e' shortcut key it's apply to a whole mesh.
Describe the solution you'd like displaying model edges only could be useful to given insight or impression about the model.
should be doabled with a vtkFeatureEdges filters, but there is no such "SurfaceWithFeatureEdges" representation. A VTK dev actually tried to add one to ParaView some time ago and it was causing some issues with z-depth conflict. May not be trivial as it looks,
thanks for the hints, regarding to difficulty in implementation. i'm only share a screenshot and experiences using another similar software as the same with VTK libraries.
i frequently discussed with him also, even i'm not really know how is complex inside. only an ordinary user which given an opinion/ideas about the modeling & post-processing of engineering simulation.
I had a look at the dataset, all the mesh is connected, so we cannot rely on just boundaries.
I agree with @mwestphal we need to use vtkFeatureEdges to process the dataset.
Could we add some kind of "edge dihedral angle" config option to achieve this feature by filtering out edges that are "flatter" that a user-defined threshold?
