The ClosestPoint method of the Line struct calculates the closest point on the line to a given position in 3D space. This method is useful for determining the nearest point on a line segment to a specified point, which can be critical in collision detection, physics calculations, or graphical applications.
To use the ClosestPoint method, you need to have an instance of the Line struct and a reference to a Vector3 position. The method will modify the pos parameter to store the closest point on the line.
Example usage:
Line line = new Line
{
Start = new Vector3(0, 0, 0),
End = new Vector3(10, 0, 0)
};
Vector3 position = new Vector3(5, 5, 0);
Vector3 closestPoint = line.ClosestPoint(ref position);
In this example, closestPoint will hold the coordinates of the point on the line that is closest to the given position.
Line line = new Line
{
Start = new Vector3(0, 0, 0),
End = new Vector3(10, 0, 0)
};
Vector3 position = new Vector3(5, 5, 0);
Vector3 closestPoint = line.ClosestPoint(ref position);
// closestPoint now contains the closest point on the line to the position.
