If anyone knows, or has a source to find out the finer details of the
math used in 3d object tracking I would appriiate knowing it.  I am
currently trying to use a ultrasonic sender in conjeuction with a base
of three recievers.  I have built the timing circuits and can figure
out the distance on all three sides of the triangle.  I can also right
three equations to solve the (x,y,z) points that are unknown, but I
cannot solve the equations.  I have tried Cramers meathod for solving
three silmultanious equations with three unknowns, but it does not
work.  Am I on the right track, or is there an easier way?  Please
help.  Thank-you.
