Vous pouvez calculer la projection d'un point P sur l'hyperplan.

Exemple de sortie écran :

 A :
+0.81250000 -0.65625000 -1.40625000 -0.65625000 
-0.25000000 +0.12500000 -1.87500000 -0.87500000 
+0.12500000 +0.43750000 +1.93750000 +0.43750000 
-0.25000000 -0.87500000 -1.87500000 +0.12500000 

 You can choose the value of the point p

 p:
+2.00000000 
+5.00000000 
+6.00000000 
+3.00000000 

 The projection of p on the hyperplan defined by v1, v2 and v3.

 Pp:            Copy this matrix into c00e.c
   -12.06250000, 
   -13.75000000, 
   +15.37500000,
