IrrlichtMt version 1.9
|
|
======================
|
|
|
|
IrrlichtMt is the 3D engine of [Minetest](https://github.com/minetest).
|
|
It is based on the [Irrlicht Engine](https://irrlicht.sourceforge.io/) but is now developed independently.
|
|
It is intentionally not compatible to upstream and is planned to be eventually absorbed into Minetest.
|
|
|
|
Build
|
|
-----
|
|
|
|
The build system is CMake.
|
|
|
|
The following libraries are required to be installed:
|
|
* zlib, libPNG, libJPEG
|
|
* OpenGL
|
|
* or on mobile: OpenGL ES (can be optionally enabled on desktop too)
|
|
* on Unix: X11
|
|
* SDL2 (see below)
|
|
|
|
Aside from standard search options (`ZLIB_INCLUDE_DIR`, `ZLIB_LIBRARY`, ...) the following options are available:
|
|
* `BUILD_SHARED_LIBS` (default: `ON`) - Build IrrlichtMt as a shared library
|
|
* `BUILD_EXAMPLES` (default: `OFF`) - Build example applications
|
|
* `ENABLE_OPENGL` - Enable OpenGL driver
|
|
* `ENABLE_OPENGL3` (default: `OFF`) - Enable OpenGL 3+ driver
|
|
* `ENABLE_GLES1` - Enable OpenGL ES driver, legacy
|
|
* `ENABLE_GLES2` - Enable OpenGL ES 2+ driver
|
|
* `USE_SDL2` (default: platform-dependent, usually `ON`) - Use SDL2 instead of older native device code
|
|
|
|
e.g. on a Linux system you might want to build for local use like this:
|
|
|
|
git clone https://github.com/minetest/irrlicht
|
|
cd irrlicht
|
|
cmake . -DBUILD_SHARED_LIBS=OFF
|
|
make -j$(nproc)
|
|
|
|
This will put an IrrlichtMtTargets.cmake file into the cmake directory in the current build directory, and it can then be imported from another project by pointing `find_package()` to the build directory, or by setting the `CMAKE_PREFIX_PATH` variable to that same path.
|
|
|
|
on Windows system:
|
|
|
|
It is highly recommended to use vcpkg as package manager.
|
|
|
|
After you successfully built vcpkg you can easily install the required libraries:
|
|
|
|
vcpkg install zlib libjpeg-turbo libpng sdl2 --triplet x64-windows
|
|
|
|
Run the following script in PowerShell:
|
|
|
|
git clone https://github.com/minetest/irrlicht
|
|
cd irrlicht
|
|
cmake -B build -G "Visual Studio 17 2022" -A "Win64" -DCMAKE_TOOLCHAIN_FILE=[vcpkg-root]/scripts/buildsystems/vcpkg.cmake -DBUILD_SHARED_LIBS=OFF
|
|
cmake --build build --config Release
|
|
|
|
Platforms
|
|
---------
|
|
|
|
We aim to support these platforms:
|
|
* Windows via MinGW
|
|
* Linux (GL or GLES)
|
|
* macOS
|
|
* Android
|
|
|
|
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.

|
The license of the Irrlicht Engine is based on the zlib/libpng license and applies to this fork, too.
