A certain distance, y0Be it is opposite with aircraft f1 to the left or to the right (weft by Dong Fangxiangwei to the left) fly out a certain distance；z0
Be it is opposite with aircraft f1 upwardly or downwardly (gravity direction is downward) fly out a certain distance；
F3:
px3 = px1+x1
py3 = py1+y1
pz3 = pz1+z1
Wherein, x1User commonly using f3 aircraft relative to f1 forward or backward (warp is by south for forward) fly out it is certain
Distance, y0Be it is opposite with aircraft f1 to the left or to the right (weft by Dong Fangxiangwei to the left) fly out a certain distance；z0It is phase
To with aircraft f1 upwardly or downwardly (gravity direction is downward) fly out a certain distance；
F4:
As long as the calculating of f4 is in the case where guaranteeing that screen side d1 and d2 is constant, so that aircraft f4 is in f1, what f2, f3 were formed
In one plane, in order to guarantee that four aircraft are in same plane, it is as follows that the embodiment of the present invention provides method of proof:
Three+t=1 parameter m, n, t, and n+m are set；
Therefore, Of1=n Of3+mOf2+(1-n-m) Of4 is arranged, is obtained
Of1-Of4 =n(Of3-Of4) +m(Of2-Of4)
That is f4f1=nf4f3+mf4f2
I.e. 4 points of aircraft f1, f2, f3, f4 are coplanar,
Therefore, as long as meeting vector relations f4f1=nf4f3+mf4f2, so that it may so that the screen is maintained at same displaying
Plane.
