hhy5277 / mundus

A 3D world/level editor built with Java, Kotlin & libGDX.

Mundus

Mundus is a platform independent 3D world editor, built with Java, Kotlin and LibGDX + VisUI. The plan is, that the world you create with Mundus can be exported into a unified format (such as JSON + assets). The exported data can then be imported into any Game Engine, if someone writes a runtime/parser for that engine.

This project is at a very early stage in development, so expect large changes in the future.

Current features

Please note, that a lot of the UI contains dummy controls for functionality that still needs to be implemented. Below are some of the more interesting features, that already work

• Creation of multiple terrains
• Height map loader for terrains
• Procedural terrain generation
• Texture splatting for the terrain texture (max 5 textures per terrain)
• A complete terrain editing system with texture & height brushes
• 4 different brushes (brush form can be an arbitrary image, like in Blender or Gimp)
• 3 brush modes for each brush: Raise/Lower, Flatten & texture paint
• A skybox (not exportable yet)
• Loading of g3db files
• Loading of obj/fbx/dae files (note, that the fbx-conv binary must be set in the settings)
• A visual translation & rotation tool (scaling coming soon)
• Multiple scenes in one project
• A component based scene graph (not fully implemented yet)
• Basic export of the project into a json format + assets
• Undo/Redo system for most operations
• Highly accurate game object picking system, based on id color coding & offscreen framebuffer rendering. Basic concept: http://www.opengl-tutorial.org/miscellaneous/clicking-on-objects/picking-with-an-opengl-hack/

Things to consider

• Mundus is constantly changing. Especially the internal representation of save files. At this stage of the project i don't care very much for backward compatibility, so don't fall to much in love with your creations if you want to stay up to date ;)
• Depending on your keyboard layout some key shortcuts might be twisted (especially CTRL+Z and CTRL+Y for QWERTZ and QWERTY layouts) because of the default GLFW keycode mapping. You can change the layout mapping in the settings dialog under Window -> Settings.

Runtime

Currently i'm in the process of implementing the libGDX runtime, which is included in this repository. Runtimes for other engines/frameworks are not planed in the near future.
