[vtkusers] Anyone knows how to calculate a specific point on a poly surface?

[Dajiang Zhu]

hi, I have a poly surface. I know two points on the surface A and B. I also
have a point C outside the surface. Now I want to find point D on the
surface which has the same distance with line AB as C. It seems like find
the intersection point with an arc and a surface. I know CellLocator can
find the intersection point with a line but how about an arc? Anyone has an
idea? Thanks


Best,


Dajiang
