Hi!

Is it possible to visualize an ellipse on Paraview? Is it possible to create a vtk file to input this type of geometry? How?

Thanks,

Marina

Menu `Sources/Alphabetical/Ellipse` create a polygonal mesh (vtkPolyData) representing an ellipse (with the given resolution).

VTK files store meshes and not parametric objects. That said you can save your created ellipse as a mesh in a vtk file: `File/SaveData`.

To followup what @nicolas.vuaille said, there is an `Ellipse` source coming to ParaView 5.8, but it is not available in ParaView 5.7. Until 5.8 is out, you can add a **Disk** source, add a **Feature Edges** filter to it to extract the circular boundary of the disk, then finally add a **Transform** filter to warp the circle into an ellipse.

ahh ok! I wasn’t finding the ellipse source. So, I will wait for this.

For now, I am using the other procedure you commented on (@cory.quammen). It worked!

Thanks,

Marina
