Read a mesh for the current segmentation

Read a mesh for the current segmentation

Usage

read_mcns_meshes(
  ids,
  units = c("nm", "raw", "microns"),
  type = c("auto", "dvid", "small"),
  node = "neutu",
  df = NULL,
  ...
)

Arguments

ids

A set of body ids in any form understandable to manc_ids

units

Units of the returned neurons (default nm)

type

One of "auto" (the default), "dvid" or "small" (see details).

node

A DVID node as returned by manc_dvid_node. The default is to return the current active (unlocked) node being used through neutu.

df

A data.frame containing information about the neurons for which meshes will be fetched. Optional and if ids is a data.frame, then that will be used.

...

Additional arguments passed to httr::GET

Value

A neuronlist containing one or more mesh3d objects.

Details

dvid meshes are pre-computed but are automatically deleted and recomputed after bodies are edited. However this process has a noticeable lag. small meshes are generated on demand in a process that can be quite slow. auto will try the dvid method and switch to small if that fails. See slack for details; this is essentially the same behaviour as the flyem clio fork.

Examples

if (FALSE) { # \dontrun{
ml=read_mcns_meshes(1796013202)
plot3d(ml)
# or if there's just one mesh, you can get more control with the rgl commands
# like wire3d
wire3d(ml[[1]])
} # }
