opensim-reflex-controllers

An OpenSim plugin creating various reflex-like controllers for muscles

This is a fork of msdemers/opensim-reflex-controllers that I updated to ensure it compiles against OpenSim 4.2 on Mac OSX. It is an OpenSim plugin that adds support for the following reflex OpenSim::Controllers:

1. Path Stretch Reflexes (length and velocity)
2. Fiber Stretch Reflexes (length and velocity)
3. Delayed stretch reflexes (constant time offset)

Building

Dependencies:

• A standard C/C++ compiler (clang, MSVC, gcc)
• CMake
• OpenSim (binaries, source - I built this against OpenSim4.2)

Build Scripts:

OS	Build Script
OSX	scripts/build_osx-catalina.sh

Running

Once you have built the library, you will can use it at the command line (opensim-cmd) like:

opensim-cmd -L /path/to/library.so <cmd>

Or in the GUI, which has some platform-dependent steps:

• Windows: copy the library into the plugins/ directory in your OpenSim install directory (e.g. C:\OpenSim 4.2\plugins). Make the plugins/ directory if it doesn't already exist. Once you copy it there, boot up the GUI. You should be able to see the plugin in Tools > User Plugins

• Mac/Linux: boot up the GUI and use the ScriptingShell to load the plugin. Open the ScriptingShell tab (near the bottom) and type the path to the library without the file suffix (e.g. .dylib):

modeling.Model.LoadOpenSimLibrary("/path/to/library")

# e.g. modeling.Model.LoadOpenSimLibrary("/Applications/OpenSim 4.2/plugins/libReflexControllersPlugin")

• Mac/Linux (cont.): any loading errors will appear in the (separate) Messages tab. Check there if there's a problem
