Instructions.
On peut déplacer le point
\(P\) dont on cherche la distance au plan, ainsi que ce plan à l’aide des points
\(A\text{,}\) \(B\) et
\(C\text{.}\) Le vecteur
\(\vec{n}\) peut aussi être changé, mais sa base est fixée au point
\(A\text{.}\) Un clic sur le premier bouton fera apparaitre le vecteur de la projection orthogonale dans une animation.
