FindClosestVertex(Point,Double,HitVertex) Method

Looks for the model vertex whose 2D screen projection is closer to the mouse cursor.

Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Function FindClosestVertex( _
   ByVal mousePos As Point, _
   ByVal maxDistance As Double, _
   ByRef closestVertex As HitVertex _
) As Integer

public int FindClosestVertex( 
   Point mousePos,
   double maxDistance,
   out HitVertex closestVertex
)

Parameters

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

Return Value

The entity index if the closest vertex is nearer than , -1 otherwise.

Remarks

The point is in the coordinate space of the CurrentBlockReference so, if there is a current BlockReference, to get the 3D world coordinates of the point you need to transform it by the CurrentTransformation.
