   ByVal maxDistance As Double _
) As HitVertex

public HitVertex FindClosestVertex( 
   Entity entity,
   Point mousePos,
   double maxDistance
)

Parameters

entity: The entity to process
mousePos: Mouse position (zero on top)
maxDistance: Limit the search to points at this distance in pixels from mouse cursor position
