I would like to share some progress on my open source project: UtyMap. This is a library which provides highly customizable API for procedural world generation based on real map data, e.g. OpenStreetMap, NaturalEarth. Core logic is written on C++11 and can be used on many platforms as it has no dependency to specific game engine or application framework. Demo application is built using Unity3D and it provides examples* with interactive world creation at different zoom levels, including globe and ground:
Globe zoom level example is not available temporary
I’m a MEng. student at Faculty of Engineering of the University of Porto (FEUP), Portugal. I have to compliment you on your project because it looks really good. I have been working with mobile exergame development with unity and map web services like Google and, now, OSM, to create a framework for mobile exergames on real-world procedural-generated 3D models.
Hope to hear more about this project when it’s finished.
Best of luck,
The latest changes introduce support of fast overview mode which renders simple pseudo 2D map skipping buildins, POI, etc. (see updates above). This can be done in the same 3D scene (see top right button in demo builds) or in separate 2D only mode.
Also offline (one time custom index construction action is required) and online (by quiring of OSM server) modes are supported.
Next demo app version will contain simple editor which allows you to add (remove?) buildings, barriers, trees (and, probably, roads, areas) dynamically into scene (ability to save changes in file also will be possible but won’t be exposed through demo app).
Still have a lot of work: just added to demo app really simple GUI editor (but it can be easily extended to add/edit/delete objects with different tag values). Now I’m focused on multiplayer feature in framework which will allow to share changes immediately over network (Unity has built-in multiplayer support).
Yeah, and bug fixing (geometry, rendering, etc.)
The latest changes in demo project demonstrate various aspect of usage:
*SimpleMap2D *scene loads 2D map of large area with low detail terrain and allows you to skip the certain objects (e.g. buildings, trees) using MapCSS rules for different zoom levels. You can also pan/zoom map.
*SimpleMap3D *scene loads one tile with all details (full detail terrain, buildings, trees) and adjusted tiles with low level of details. You can walk and interact with environment: modify facade of building, make craters. Tiles will be loaded/unloaded automatically.
GpsTracking scene demonstrates how to work with Location Services (e.g. GPS). Nmea file is used as GPS signal source to simulate movement.
*GuiEditor *scene demonstrates several features: map editor (create new map object such as buildings, barriers, trees; adjust terrain height), current address resolution (detects where you are), dynamic switch between 2D/3D maps (2D map shows larger area). You may find video which shows this scene in action above.
Working on rewriting core logic using C++ to make it completely independent from Unity3D and increase performance. Also support of multiply zoom levels are planned (e.g. render Earth as globe on zoom level one and buildings/all details in 3D on highest level).
