To develop a $3$D scene, you need:

$1.$ Create $3$D objects. A $3$D scene must contain at least five $3$D objects. If a $3$D object

contains many component elements $($five or more component objects$),$ then such a

"complex" object can be on the scene alone.

$2.$ Add textures and materials for $3$D objects.

$3.$ Animate $3$D objects. The duration of the animation should be at least $20$ seconds.
