- Yields the Cartesian parametric 3D surface for the given x-expression (first <Expression>), y-expression (second <Expression>) and z -expression (third <Expression>), using two parameter variables within the given intervals [<Start Value>, <End Value>].
- Beispiel: Let r and R be two positive real numbers:
Surface[(R + r cos( u)) cos(v) , (R + r cos( u)) sin(v) , r sin(u ), u, 0, 2 π , v, 0, 2 π]creates the torus generated by a circle of radius r whose center rotates about zAxis at a distance R.
- Anmerkung:
- End Value must be greater than or equal to Start Value and both must be finite.
- x, y and z are not allowed as parameter variables.
