TurtleGL-3d

Create a fully-functional 3D space simulation game using the 'TurtleGL-3d' package in Python. The game should allow players to navigate through a procedurally generated solar system, consisting of planets, moons, asteroids, and stars. Players should be able to control a spaceship to explore these celestial bodies and collect resources such as minerals and fuel.

Step-by-step guide:
1. Set up the initial environment with a sun at the center and several planets orbiting around it. Use TurtleGL-3d to render these objects in 3D space.
2. Implement a camera control system that allows players to move their spaceship forward, backward, left, right, up, and down using keyboard inputs. Utilize TurtleGL-3d's capabilities for handling 3D transformations and rotations.
3. Create a day-night cycle effect for each planet, changing its appearance based on the position of the sun relative to the player's viewpoint. This will involve adjusting lighting and shading effects using TurtleGL-3d.
4. Introduce different types of celestial bodies, each with unique characteristics. For example, planets may have different atmospheres and gravity levels, while asteroids could contain valuable resources.
5. Add a resource collection mechanic where players can gather resources from various celestial bodies by flying close enough to them. Resources should be stored in a virtual inventory managed by your game logic.
6. Implement a simple collision detection system to prevent players from crashing into planets or other obstacles. Use TurtleGL-3d's geometry functions to detect when the spaceship intersects with other objects.
7. Include a scoring system that rewards players for collecting resources efficiently and completing certain objectives within time limits.
8. Enhance the visual appeal of the game by adding particle effects for things like engine thrusters and asteroid impacts. Leverage TurtleGL-3d's animation features to create smooth transitions and dynamic visuals.
9. Finally, consider adding a user interface for displaying the player's score, current resources, and other relevant information. This UI can be overlaid on top of the main 3D view provided by TurtleGL-3d.

Suggested Features:
- Procedural generation of new solar systems each time the game is played.
- Different types of spaceships with varying performance characteristics.
- Multiplayer mode allowing multiple players to explore the same solar system simultaneously.
- Mini-games or challenges within the game, such as avoiding collisions with incoming asteroids or landing on a specific type of planet.

By following these steps and incorporating these features, you'll create an engaging and visually appealing 3D space exploration game using the powerful capabilities of the TurtleGL-3d package.
