H5Renderer

H5Renderer

• compile via make using Makefile
• adjust settings in h5renderer.info (image height, system size, ...)
• execute binary bin/h5renderer
  • e.g. ./H5Renderer/bin/h5renderer -c <H5Renderer config file> -i <input directory with HDF5 files> -o <output directory>

Create images from HDF5 files.
Usage:
  h5renderer [OPTION...]

  -c, --config arg  Path to config file (default: h5renderer.info)
  -v, --verbose     More printouts for debugging
  -i, --input arg   Read files from given path (otherwise from config file) 
                    (default: -)
  -o, --output arg  Write result files to given path (default: ./output)
  -x, --mark        Mark particles as + instead of points
  -z, --zoom arg    Zoom in factor to show more details (default: 1)
  -h, --help        Show this help

• for creating a mp4 from the images: ./H5Renderer/createMP4From <input directory with images> (based on ffmpeg)
• for creating a gif from the mp4: ./createGifFromMP4

./createMP4From

ffmpeg -pattern_type glob -i "$1*.ppm" -vcodec libx264 -s 1024x512 -pix_fmt yuv420p $1movie.mp4

• particle data loaded from H5/HDF5 files
  • including positions (/x), keys (/keys) and (/ranges)
• particles mapped to pixels according to their position and colored according to their process assignment (via key and ranges)
