C++ Plugins Example¶
This example registers multiple node plug-ins written in C++.
- LerpExample.cpp: A simple node which interpolates two floats.
- TransformGeometryExample.cpp: A node which transforms a geometry vertices by a matrix.
- register.cpp: Registers the plugins.
Windows Compilation¶
Prerequisite¶
- Visual Studio with the Visual Studio 2015 (v140) Plateform Toolset installed.
- CMake >= 3.10
Compile¶
cd rumba/sdk/examples/cxx_plugins
mkdir build
cd build
cmake .. -G "Visual Studio 14 2015 Win64" "-Drumba_DIR=rumba_installation_path/sdk/"
cmake --build . --config Release
Linux Compilation¶
Prerequisite¶
- clang-9, or another modern C++ compiler like clang >= 7, gcc >= 9
- CMake >= 3.10
Compile¶
To compile with clang-9
cd rumba/sdk/examples/cxx_plugins
mkdir build
cd build
CXX=clang-9 cmake .. "-Drumba_DIR=rumba_installation_path/sdk/"
cmake --build .
To compile with your default compiler
cd rumba/sdk/examples/cxx_plugins
mkdir build
cd build
cmake .. "-Drumba_DIR=rumba_installation_path/sdk/"
cmake --build .
Installing the plug-ins¶
You have now to register your plug-ins in Rumba. To do that, add the directory plug-in path to the RUMBA_USER_PLUGINS environment variable:
RUMBA_USER_PLUGINS=path_to_the_plugin_binaries"
Register with MTORBA¶
If your plug-in is the translation of an existing Maya plug-in, you also want to register it with MTORBA in order to be exported from Maya.
To do that, you need to write a MTORBA ‘exporter’ script. You have lot of exporter samples in module/python/mtorba/exporters/. Place your exporters in a folder and add the path of this folder to the MTORBA_USER_EXPORTERS environment variable. MTORBA will load them automatically.
