A neuroglancer data dump consists of a mix of JSON and custom binary data files, which together define mesh data for (fragments) of neurons together with associated metadata. See fetch_all_curl for how to prepare such a data dump.

Examples

if (FALSE) {
fetch_all_curl("all_curl.sh", outdir="alldata",
  regex="brainmaps.googleapis.com", fixed=TRUE)
meshdata=read_ng_dump("alldata")
m=as.mesh3d(meshdata)
shade3d(m, col='red')

# can also be a (remote) zip file
meshdata=read_ng_dump("https://myfiles.com/myneuron.zip")
