Easiest way to get the world coordinate out of a clicked location for debugging

[sedghi]

Two questions:

• How can I efficiently (easily) obtain a world coordinate from clicking on a viewport for debugging purposes?
• What's the simplest method to retrieve the actor and mapper for each viewport? is there any utilities on window similar to vtk examples?

Thanks!

console.log here? https://github.com/Kitware/VolView/blob/main/src/vtk/RulerWidget/behavior.ts#L92

Tricker. Here is a spot where to can get the "slice" actor/mapper pair associated with a "view": https://github.com/Kitware/VolView/blob/main/src/components/vtk/VtkBaseSliceRepresentation.vue#L36
