CreateSpace restituisce 20 punti tra a0 e a1. Tali punti sono connessi in modo da formare una curva 3D.

Tre funzioni di un singolo parametro

1. Definire tre funzioni distinte per il raggio, l'angolo orizzontale e l'angolo verticale in coordinate sferiche.

2. Definire il numero di punti tracciati.

3. Definire la curva utilizzando CreateSpace. Aggiungere sph2xyz come ultimo argomento. Si tratta di una funzione incorporata per mappare coordinate sferiche a coordinate XYZ. Quindi, è possibile tracciare un grafico 3D regolare delle coordinate sferiche.

Tre funzioni di due parametri

1. Definire tre funzioni da tracciare, che rappresentino le tre coordinate.

2. Definire le dimensioni della mesh di input delle due variabili. Definire il numero di punti negli intervalli di u e v.

3. Utilizzare la funzione incorporata CreateMesh e tracciare il grafico del risultato.
