README.md

This is the base of ogs to let it run on supported platforms and display an empty screen, nothing more.

The base consists of:

OpenSceneGraph/
- custom configuration to build OpenSceneGraph for supported platforms
features/
- source code variants of OGS
platforms/
- platform specific build and configuration files

OpenSceneGraph/

OpenSceneGraph is a versatile C++ library to render 3D with OpenGL.

OpenSceneGraph directory contains:

CMakeLists.txt
- Is a configuration file for CMake
- Builds OpenSceneGraph components (osgViewer, osgUtil, etc.) as static libraries
- Builds OpenSceneGraph for linux, macos, and web
  - android and windows are coming later
  - ios is supported by Xcode project, not CMake one
include/
- Contains platform specific headers for OpenThreads and OpenSceneGraph
  - The headers were generated by original OpenSceneGraph's CMake configuration process for each supported platform
  - They are kept in the repository to support custom OpenSceneGraph configuration
include-gen/
- Contains simplistic OpenSceneGraph applications to generate platform specific headers for ios and web
src/
- Contains custom sources to build OpenSceneGraph fast
- Speedup is achieved by combining several sources into one

Notes:

Place original OpenSceneGraph distribution directory alongside ogs directory because custom sources reference original OpenSceneGraph distribution sources

Features represent source code variants that may be easily switched on or off.

TODO Update feature-tool to better describe its purpose and usage.
