How to creat a oblique cylinder?

[Pandakii]

Hi everyone,
The implicit function CylinderIF can be used to construct a cylinder that is parallel to the coordinate axis. How to make use of implicit functions to creat a oblique cylinder with a angle relative to the coordinate axis? Or, is it possible to rotate the normal cylinder around a point?

We have a rotated cylinder option in PeleC: https://github.com/AMReX-Combustion/PeleC/blob/development/Source/Geometry.cpp#L293. eb2.geom_type = "rotated_cylinder" and you can see the options it is looking for in that source code I linked to. E.g.: eb2.cylinder_radius = 1.0 and eb2.cylinder_rotation_axe = 2 can be used in your input file.
