I would like to plot the following hyperboloid in 3d. Given the center c = <18,0,0>, principal axis vector v = <-1,0,0>, orthogonal vectors u = <0,1,0>, and w = <0,0,1>, and parameters A = 3, B= 17.748, so that C^2 = A^2 +B^2, and C/A is the eccentricity. I can express the hyperboloid as follows:
c + A*sec(x)*v + B*tan(x)*u*cos(y) + B*tan(x)*w*sin(y)
0 <= x < pi/2, and
0 <= y <= 2*pi.
I have not been able to get this to work in pstricks format. The expressions work, because I can plot the hyperboloid in Maple using the above.
