In This Topic

Tells if the projected point, whose square distance from the mouse cursor is , is closer than the .

Syntax

Visual Basic

'Declaration
 
Protected Friend Overridable Function IsCloserVertex( _
   ByVal projectedPt As Point3D, _
   ByVal squareDistance As Double, _
   ByVal currentMinimumSquareDistance As Double _
) As Boolean

protected internal virtual bool IsCloserVertex( 
   Point3D projectedPt,
   double squareDistance,
   double currentMinimumSquareDistance
)

Parameters

projectedPt: The point in projected Camera coordinates
squareDistance: The 2D square distance from the mouse position
currentMinimumSquareDistance: The current minimum 2D square distance from the mouse position

Return Value

True if the point is closer, false otherwise.

Remarks

This method is used by the FindClosestVertex(Point,Double,Point3D) to compute the closest vertex to the mouse in 2D. Override this method to consider also the Z of the .
