[X3D-Public] Any way to do a 'LineSensor' (Like PlaneSensor but in one dimension)

Fri Sep 24 19:12:41 PDT 2010

  Hey Keith,

Yeah I used Studio to create the basic sensor stuff (as below) and then 
restrict X or Z. The problem is as Sergey described. Not an easy fix. I 
may go with the (drum roll) custom node 'device sensor' to intercept 
mouse events and process as needed.
