示例1: LineSegmentIntersectsPlane
/// <summary>
/// Determines the intersection of a line segment between v1 and v2 and the given plane.
/// Returns false if the plane is outside the line segment or parallel to it.
/// </summary>
public static bool LineSegmentIntersectsPlane(Vector3 v1, Vector3 v2, Plane plane, out Vector3 pos)
{
var vector = v2 - v1;
var direction = Vector3.Normalize(vector);
var ray = new Ray(v1, direction);
var dist = ray.Intersect(plane);
if (!float.IsNaN(dist) && dist * dist < vector.LengthSquared())
{
pos = ray.Position + (ray.Direction * dist);
return true;
}
pos = Vector3.Zero;
return false;
}示例2: ClosestPointToPlane
/// <summary>
/// Determines the closest point on the ray from v1 to v2 and the given plane.
/// Returns false if the plane is parallel to the line.
/// </summary>

{
var direction = v2 - v1;
var ray = new Ray(v1, direction);
var dist = ray.Intersect(plane);
