_Feel free to leave suggestions / feature requests on the issue tracker, especially regarding ease of use._

## Current status
The system is mostly working. I am now testing / polishing the interface and adding a few features. I will make a first release before implementing PVS as PVS is an optional feature.

## Roadmap
* Auto conversion of named room spatials and portal mesh instances to LRoom and LPortal DONE
* Auto creation of mirror portals DONE
* Recursive determine visibility DONE
* Prevent memory allocations (use pools for plane vectors) DONE
* Add support for objects moving between rooms - cameras, players, physics etc - DONE
* Refactor code, moving LRooms and LPortals outside scene graph DONE
* Cleanup code, Optimize DONE
* Handle special cases (multiple portals views into room etc) DONE
* Bug fixing / testing ONGOING
* Optimize non-moving statics DONE
* Closable portals
* PVS (primary and secondary)
* Investigate multiple passes (shadows, lights)

## Instructions
See INSTRUCTIONS.md

## Installation
You will need to compile Godot from source (for now). See:
http://docs.godotengine.org/en/3.0/development/compiling/index.html

Once the engine is compiling okay on your system, to add the module:
* Create a folder inside godot/modules called 'lportal'
* Clone / download this repository as a zip file and place the files in the lportal folder
* Compile the engine as normal, it should automatically pick up the lportal module
* Note that to export to other platforms you will also have to compile export templates for those platforms

You will know the installation was successful when you see a new Node type 'LRoomManager' in the Godot IDE.
