4 The Irrlicht Engine is an open source realtime 3D engine written in C++.
6 This is a fork by the [Minetest](https://github.com/minetest) developers that contains features, customizations and fixes specifically for use in Minetest.
11 The build system is CMake.
13 The following libraries are required to be installed:
14 * zlib, libPNG, libJPEG
16 * or on mobile: OpenGL ES (can be optionally enabled on desktop too)
19 Aside from standard search options (`ZLIB_INCLUDE_DIR`, `ZLIB_LIBRARY`, ...) the following options are available:
20 * `BUILD_SHARED_LIBS` (default: `ON`) - Build IrrlichtMt as a shared library
22 e.g. on a Linux system you might want to build for local use like this:
24 git clone https://github.com/minetest/irrlicht
26 cmake . -DBUILD_SHARED_LIBS=OFF
32 We aim to support these platforms:
38 This doesn't mean other platforms don't work or won't be supported, if you find something that doesn't work contributions are welcome.
43 The license of the Irrlicht Engine is based on the zlib/libpng license and applies to this fork, too.
