Environment.FindClosestVertex (Point, Double, Point3D) Method

Looks for the model vertex whose 2D screen projection is closer to the mouse cursor.
Public Function FindClosestVertex( _ 
ByVal mousePos As Point, _ 
ByVal maxDistance As Double, _ 
ByRef closest As Point3D
) As Integer

public int FindClosestVertex( 
Point mousePos
double maxDistance
out Point3D closest 
)
This language is not supported or no code example is available.

Parameters

mousePos
Point

Mouse position (zero on top)

maxDistance
double

Limit the search to points at this distance in pixels from mouse cursor position

closest
Point3D

The closest vertex as a 3D point

Return Value

int

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

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