In a 3D plane, I have another plane P1 equal to Ax+By+Cz=0 (D=0 since one of its points is (0,0,0) )

If I have the coordinates (x1,y1,z1) in the first plane, what are the cordinates of this point in the P1 plane?

I know the equation of the intersection line. But my calculations are going wrong, I'm afraid... And I thing it's because of the inclination rotations routines...

And I also think that a starting x-axis vector must be defined - from the intersection line.

Can someone help?

Kind regards,
