FindClosestVertex(Point,Double,Int32) Method

In This Topic

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 closestIndex As Integer _
) As Integer

public int FindClosestVertex( 
   Point mousePos,
   double maxDistance,
   out int closestIndex
)

Parameters

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

Return Value

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

Remarks

The returned entity index refers to the Entities if there is no current BlockReference, else it refers to the Block.Entities of the Block referred by the CurrentBlockReference. Also, 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.
