Przykłady

W poniższym przykładzie pokazano, jak uzyskać kąt między dwiema Vector3D strukturami.

                    // Calculates the angle between two Vector3Ds using the static AngleBetween method. 
                    // Returns a Double.

                    Vector3D vector1 = new Vector3D(20, 30, 40);
                    Vector3D vector2 = new Vector3D(45, 70, 80);
                    Double angleBetween;

                    angleBetween = Vector3D.AngleBetween(vector1, vector2 );
                    // angleBetween is approximately equal to 4.15129

' Calculates the angle between two Vector3Ds using the static AngleBetween method. 
' Returns a Double.

Dim vector1 As New Vector3D(20, 30, 40)
Dim vector2 As New Vector3D(45, 70, 80)
Dim angleBetween As Double

angleBetween = Vector3D.AngleBetween(vector1, vector2)
' angleBetween is approximately equal to 4.15129

Uwagi

Kąty ze znakiem nie rozciągają się na przestrzeń 3-W, więc zwracany jest kąt z zakresu od 0 do 180 stopni.
