Dear Luca,
I am using the vmtksurfacedistance to check whether a point is inside or
outside a closed manifold surface.
Points inside and points outside are generally correct but sometimes I get a
wrong sign.
By looking at the wrong points it seems that a wrong sign is assigned when the
closest surface point (on the distancevectorsarray)
is too close to a surface node or a surface edge.
1) The distancevectorsarray is correct. So, is it possible that during the DOT
product, the normal is not well defined if the point is too close
to a node or an edge?
2) Is it possible to force vmtksurfacedistance to return the
distancevectorsarray with the closest surface nodes (cartesian distance)
instead of closest surface points? In this way, one could calculate the dot
product outside vmtksurfacedistance.
Kind regards
Gianluca
