Shap3d34.dat, 34th 'shape' file for CPO3D

A torus, using the option for users equations, replaces shap3d18.

It is similar to shap3d33, but with 'a' larger and 'b' smaller, and with theta and phi both covering -pi/2 to pi/2.

See users equations for further information.

The equations, as they appear in the data file, are:

theta -1.57 1.57 name of variable number 1 and its limits

phi -1.57 1.57 name of variable number 2 and its limits

a 1 name of parameter number 3 and its fixed value

b 0.25 name of parameter number 4 and its fixed value

0 0 name of parameter number 5 and its fixed value

0 0 name of parameter number 6 and its fixed value

b*cos(theta)

(a+b*sin(theta))*cos(phi)

(a+b*sin(theta))*sin(phi)

1 1 numbers of 2 applied voltages (can be same)

10 10 numbers of subdivisions of variables 1 and 2

(The program has corrected the less accurate value that was entered for pi/2.)
