I want to make the ball appear 3d when it moves, similar to microgolf.triplefun.com this game.

This is not a Game Design question. What Is Game Design? Moved to a more appropriate forum.

This ball seems “3d” at all times, it's probably a simple convex mesh that is rotated and translated according to the simulated movement of the ball (treated as a perfect sphere).

Aren't you using a game engine that allows drawing and moving such a simple 3d model easily? What do you find challenging?
