Vous pouvez calculer la projection d'un point P sur le plan.
Exemple de sortie écran :
A :
+2.363636363638 -1.909090909092 -0.272727272727
+1.818181818184 -1.545454545456 -0.363636363636
-0.909090909092 +1.272727272728 +1.181818181818
You can choose the value of the point p
p:
+2.0
+5.0
+6.0
The projection of p on the plan defined by v1 and v2.
Pp: Copy this matrix into c00e.c
