# v0.12: Chris Ringeval (eatdirt):
# -add normalmapping output + small improvements.
#
# v0.14: Chris Ringeval (eatdirt):
# -add alpha channel as inverse height to normalmap (normalmap binary
# modified, forked from plainrich), allows for changing memory limits
# and resizing method.
#
# v0.15: Chris Ringeval (eatdirt):
# - add support for downloading world textures for a given month. Done
# by appending the name of the month to the command line. Default is
# as before, namely August.
# - change the way to make border. Instead of stretching the last
# pixel, we crop the corresponding part on the neighboring
# tiles. This prevents the appearance of seams with parallax mapping.
#
VERSION="v0.15"
# make sure the script halts on error

echo " 1k 2k 4k 8k 16k cleanup rebuild ]"
echo
echo "* Append \"no-download\" to the command to skip the download"
echo " process alltogether. Only makes sense if you already got"
echo " the necessary data."
echo "* Append \"world\" to the command to generate the world tiles"
echo "* Append \"clouds\" to the command to generate cloud tiles"
echo "* Append \"heights\" to the command to generate height tiles"
echo " and the normalmaps needed by EarthView. Notice that you need"
echo " the normalmap binary to be installed. You can get it from:"
echo " https://github.com/eatdust/normalmap"
echo "* Append \"all\" to the command to generate all - world, clouds"
echo " and heights"
echo "* Append the size of the tiles (1k, 2k, 4k, 8k, 16k). If you"
echo " don't pass a resolution, then all resolutions will be"
echo " generated."
echo "* Append \"cleanup\" to delete all temporary files in tmp/"
echo " Same as \"./convert.sh world clouds rebuild\""
echo " Useful if the source files have changed."
echo "* Append \"rebuild\" to remove the corresponding temp-files"
echo " of your requested target."
echo " If you have \"world\" as target, that means all files in"
echo " tmp/world* and tmp/night* will be deleted, so that the"
echo " script will have to rebuild the entire set of files."
echo " So, if clouds and world are requested, effectively all temp-"
echo " files will be deleted (same as cleanup)"
echo " Useful if the source files have changed."
echo "* Append \"check\" to let check the results. This will create"
echo " mosaics of the existing tiles. If no target is specified,"
echo " all layers will be built: clouds, heights, world and nightlights."
echo
echo "If, for some reason, the script aborts, then it will try to"
echo "skip the already completed steps, so you don't have to wait"
echo "for the first steps to be redone. Those also happen to be the"
echo "most heavy loads on the ressources."
echo
echo "WARNING!"
echo "This script uses a _lot_ of disk space! Make sure you choose"
echo "a disk, with at least 90GB free space."
echo
echo "This script will take a very long time, depending on your CPU"
echo "and memory. It's propably best, to let it run over night..."
echo
echo "Examples:"
echo "./convert.sh world clouds"
echo "Will generate all textures needed for EarthView"
echo
echo "./convert.sh rebuild clouds no-download"
echo "Will skip the download function and will proceed under the"
echo "assumption that the download has previously finished"
echo "correctly. Furthermore it will only generate the cloud-"
echo "textures. Before that all temp-files will be deleted, so that"
echo "the textures will be generated from scratch."
echo
echo "./convert.sh cleanup"
echo "Will delete all temp-files, so that on the next run"
echo "everything will have to be regenerated from scratch. Useful"
echo "if the source images have changed."
echo
echo "./convert.sh world 4k"
echo "Will generate only tiles of the world of 4096x4096 size."
