given a set of 3 plane equation, how can i find the intersection point for all plane?

Solve the system formed by the 3 plane equations , there are some detail about the theory , in particular about the determinat meaning that you may obtain imaginary intersections, just open a book about 3d geometry and read it.

From three given plane equations:ax + by + cz = jdx + ey + fz = kgx + hy + iz = lYou form a system:AX = Ywhere    a b c        x             jA = d e f ,  X = y   and   Y = k    g h i        z             lIf det A is separated from 0 then the system has a uniqe solution.Also, A is invertible and the solution can be written as follows:X = inv(A)Ywhere inv(A) means the inverse of A.Here X holds the coordinates of the intersection point.
