Hi zbyszek,

The easiest technique to define an explicit composition:

P phi(const P& arg) { ... } // parametrized surface
G g(double t) { return P(t, t); }
P F(double t) { return phi(g(t)); }

or

P phi(double u, double v) { ... }
P F(double t) { return phi(t, t); }

Please ask if that isn't what you're looking for.
