tool error defining intersecting point line an plane
thinking about the question in defining shadow I tried to create a new tool that does this: given a lightpoint P, a second point A and a plane a it creates the shadow B of the given point in the plane a.
Manually it's no Problem, since B is just the intersection point of the line b through P and A and the plane a.
So I defined a tool with
- Output Objects: Line b through P,A and Point : Intersection point of b,a
- Input Objects: Point P, Point A, Plane a
But when I proceed to the tab Name and Icon I get an Error message: processing of command Intersect[b,a].
Can any one explane why the intersection point isn't calculated or give an alternative?
