Windows (AMD64, ARM64), MacOS (ARM), and ubuntu24.04 (AMD64) with python 3.12 only. Otherwise, you will need to build the dependencies manually. (see https://pypi.org/project/libcalab-ogre3d/ for the list of prebuilt binaries available on PyPI)

  pip3 install numpy torch python3-tk gymnasium libcalab_ogre3d stable-baselines3 opt_einsum easydict mujoco clarabel scipy transformations
  python3 walk_SRBTrack2025.py

Choose the D3D (windows), openGL (ubuntu), or metal renderer (mac) if asked to choose one. Also, on Linux, choose 1920x1080 resolution. If you already chose a different resolution, re-try after deleting ogre2_linux.cfg

env, gym_trackSRB folders contain the source codes of "SRBTrack: Terrain-Adaptive Tracking of a Single-Rigid-Body Character Using Momentum-Mapped Space-Time Optimization"

  pip3 install torch python3-tk gymnasium libcalab_ogre3d stable-baselines3 libcalab_ogre3d
  python3 walk_SRB2023.py

Choose the D3D (windows), openGL (ubuntu), or metal renderer (mac) if asked to choose one. Also, on Linux, choose 1920x1080 resolution. If you already chose a different resolution, re-try after deleting ogre3_linux.cfg (On linux, the resolution specified in ogre3_linux.cfg should match the one in site-packages/libcalab_ogre3d/Resource/ogreconfig_linux12.txt)

gym_cdm2 contains the source codes of "Adaptive Tracking of a Single-Rigid-Body Character in Various Environments".

  pip3 install torch python3-tk gymnasium libcalab_ogre3d
  python3 walk_FlexLoco2020.py 

Now, click the play button, and adjust the slider bars for speed/orientation. Also, you can change the motion type by clicking the button.

work/gym_walkCDM contains the source codes of "Fast and Flexible Multilegged Locomotion Using Learned Centroidal Dynamics".

todo: this part needs to be updated.

1. First, install necessary dependencies. This probably installs more than actually necessary:

	sudo apt install libfltk1.3-dev libreadline-dev  wxpython-tools
	cd dependenceies/lua5.1; make install_linux 
  mkdir ogre-next-source;  cd ogre-next-source; git clone https://github.com/OGRECave/ogre-next.git; cd ogre-next; git checkout 50bbee7d
	cd dependenceies/ogre-next3; cp -rf ../ogre-next-source/ogre-next/* . 

Then you need to apply the patch file in the dependencies/ogre-next3 as follows (untested. you can do this manually by looking at the patch file).

    cd dependences/ogre-next3;patch -p0 < ogre-latest_50bbee7d.patch

2. Now you can build ogre-next (latest):

   cd dependencies/ogre-next3
make linuxbuild

3. Also install python3 and pip3 (versions do not matter.)

4. Now, build this project.

	pip3 install stable-baselines3 torch numpy gymnasium
  cd src; make

This should work on any versions of ubuntu.

1. First, install necessary dependencies:

  brew install fltk eigen gsl cmake 
  pip3 install wxPython
	cd dependenceies/lua5.1; make install_macosx 
  mkdir ogre-next-source;  cd ogre-next-source; git clone https://github.com/OGRECave/ogre-next.git; cd ogre-next; git checkout -b v2-3 remotes/origin/v2-3
	cd dependenceies/ogre-next3; cp -rf ../ogre-next-source/ogre-next/* . 

Then you need to apply the patch file in the dependencies/ogre-next3 as follows (untested. you can do this manually by looking at the patch file).

	cd dependences/ogre-next3/ogre-next-deps/src/freetype/src;git checkout -f gzip/zconf.h;patch -p1 gzip/zconf.h < ../../../../zconf.patch
    cd dependences/ogre-next3;patch -p0 < ogre-latest_50bbee7d.patch

2. Now you can build ogre-next3 (latest):

   cd dependencies/ogre-next3
make macbuild

3. Also install python3 and pip3 (versions do not matter.)

4. Now, build this project.

FYI, most linker and compiler settings are in src/taesoolib/Samples/Common_baselib.cmake and Common_mainlib.cmake files.

src/taesooLib contains the taesooLib. All of my research projects rely on this library, which contains C++ code related to motion loading, inverse kinematics (IK), rendering, and more.

src/taesooLib/BaseLib contains the core library which is GUI-independent.

src/taesooLib/MainLib extends the core library with Ogre3D and FLTK-based GUI components.

src/taesooLib/PhysicsLib contains a few rigid-body simulators.

src/taesooLib/MainLib/WrapperLua/luna_mainlib.lua defines the functions and classes that can be used in lua scripts.

src/taesooLib/MainLib/python/MainlibPython.hpp defines the functions and classes that can be used in python scripts.
