Question 1

How to set up 3d.city locally for development?

Accepted Answer

The README doesn't provide detailed instructions, but you can clone the GitHub repository and run the HTML files directly. Ensure you have a modern browser with WebGPU support enabled, and note that Three.js dependencies may need manual handling due to the minimal setup.

Question 2

Is 3d.city good for learning Three.js and WebGPU in games?

Accepted Answer

Yes, it's an excellent resource for seeing Three.js integrated with WebGPU for high-performance 3D graphics, and the use of web workers for simulation offers practical insights into optimizing web applications. However, the incomplete documentation means you'll need to explore the code yourself.

Question 3

Can I modify the 3D models in 3d.city for my own project?

Accepted Answer

Yes, the GLB models are custom-made and open-source, so you can edit them with 3D software. However, integrating changes might require familiarity with Three.js and the project's structure, as there are no guides provided.

Question 4

How does 3d.city compare to other web-based city builders like Citybound?

Accepted Answer

3d.city focuses on performance with WebGPU and minimal size, making it more experimental and optimized for modern browsers, whereas Citybound might offer more features but with different technical trade-offs. 3d.city is better for learning cutting-edge web tech but less feature-complete.

Question 5

What browsers support 3d.city's WebGPU version?

Accepted Answer

It requires browsers with WebGPU support, such as Chrome or Edge with enabled flags, and may not work on Safari or older versions. The WebGL fallback is available but might have reduced performance on less capable devices.

Question 6

Are there any tutorials for adding new features to 3d.city?

Accepted Answer

No, the README lacks tutorials, and the project's 'Work in progress' status means you'll likely need to rely on Three.js documentation and experiment with the codebase to implement additions like new buildings or simulation rules.

Question 7

Does 3d.city have plans for multiplayer or online features?

Accepted Answer

Currently, it's focused on single-player simulation with no mention of multiplayer in the README. Adding such features would require significant custom development, as the codebase isn't designed for it out-of-the-box.
