How do I start building a project with a world map and 3D models?

Honestly, my initial thought is to reconsider if you should take on this project alone. However, if you do, remember the basic steps: gather your requirements, plan and design your project, develop, test, deploy, and maintain it. Each of these steps is crucial for a successful outcome.

It sounds like you have a unique project ahead of you! Since it's quite involved, a good starting point is to break it down into specific questions. For example, consider asking about the tools for map integration or how to render 3D models in a web environment. Keep your questions focused and specific to get the best help from the community.

For a project like this, you might find inspiration from existing applications. I created a town and world map using CSS where I placed buttons linked to specific locations. It’s a simple way to visualize your map without getting too complicated, which could help you brainstorm ideas!

Before diving into development, check online to see if there's an existing solution that matches your needs or at least part of it. It might save you a lot of time and resources. If you find something, analyze its cost and complexity. Sometimes using a platform that already has a similar feature can be more economical than building from scratch!
