Bhvparser

This is a library that parses .bvh (motion capture, BioVision Hierarchy) files to a C++ representation of the skeleton and the motion.

Two applications are included:

• bvhtox3d is a command line tool converts a .bvh file to a virtual reality file .x3d.
• bvhshow is a GUI application that reads .bvh-files and shows the animated skeleton.

Requirements (for bvhshow)

• flex and bison tools for parser generation
• glew OpenGL binding
• fltk GUI Toolkit Version 1.4.1

How to build

.. on Linux

• Install flex and bison: sudo apt-get install flex bison or equivalent

• Make sure glew is installed

• Provide development files for fltk 1.4.1. If fltk 1.4.1 is not installed already, build from source:

  cd somewhere
  git clone https://github.com/fltk/fltk
  cmake -S fltk -B fltkbuild \
      -D CMAKE_CONFIGURATION_TYPES="Debug;Release" \
      -D FLTK_BUILD_EXAMPLES=0 \
      -D FLTK_BUILD_FLTK_OPTIONS=0 \
      -D FLTK_BUILD_TEST=0 \
      -D FLTK_OPTION_FILESYSTEM_SUPPORT=0 \
      -D FLTK_OPTION_SVG=0 \
      -D FLTK_BUILD_FLUID=0
  

• make all

.. or else on Windows (using Visual Studio 2022 (VS17))

• Easy way to install flex and bison: Download single executable implementations win_flex und win_bison from here and put them on the PATH. If you name them differently or don't want them on the path, adapt the Macros FLEX and BISON in buildsys/VS17/bvhparser.props.

• Easy way to provide development files for glew: Download the latest release (currently 2.2.0) of windows binary files from here.
  Copy lib/Release/x64/glew32s.lib from the archive to lib/Release/glew32s.lib and lib/Debug/glew32s.lib in the repository.
  Copy include/GL/*.h from the archive to include/GL/ in the repository.
  If you have glew installed elsewhere, adapt paths and filenames in buildsys/VS17/UseGlew.props.

• If you have development files for fltk 1.4: Edit buildsys/VS17/UseFLTK.props to adapt file names and paths.
  Otherwise build from source (on windows command line):

  cd somewhere
  git clone https://github.com/fltk/fltk
  cmake -S fltk -B fltkbuild ^
      -D CMAKE_CONFIGURATION_TYPES="Debug;Release" ^
      -D FLTK_BUILD_EXAMPLES=0 ^
      -D FLTK_BUILD_FLTK_OPTIONS=0 ^
      -D FLTK_BUILD_TEST=0 ^
      -D FLTK_OPTION_FILESYSTEM_SUPPORT=0 ^
      -D FLTK_OPTION_SVG=0 ^
      -D FLTK_BUILD_FLUID=0
  

  Build the created solution. Adapt buildsys/VS17/UseFLTK.props to use the created files or copy libraries and headers to the given paths.
