The GetPositionOnPlane method calculates the intersection point of a ray with a plane defined by a position and a normal vector. This method is useful for determining where a ray intersects a plane in 3D space, which can be applied in various scenarios such as object placement or collision detection.
To use the GetPositionOnPlane method, provide the following parameters:
position: A Vector3 representing a point on the plane.planeNormal: A Vector3 representing the normal vector of the plane.ray: A Ray object representing the ray to be tested for intersection with the plane.The method returns a Nullable<Vector3> which contains the intersection point if the ray intersects the plane, or null if there is no intersection.
// Example usage of GetPositionOnPlane
Vector3 planePosition = new Vector3(0, 0, 0);
Vector3 planeNormal = new Vector3(0, 1, 0);
Ray ray = new Ray(new Vector3(1, 1, 1), new Vector3(0, -1, 0));
Vector3? intersectionPoint = Gizmo.GetPositionOnPlane(planePosition, planeNormal, ray);
if (intersectionPoint.HasValue)
{
// Intersection point exists
Vector3 point = intersectionPoint.Value;
// Use the intersection point for further processing
}
else
{
// No intersection
}
