If you have an image-like object and you want to turn it into a
matrix of 3D coords then you need ind2coord. For the reverse
operation we offer as.im3d.matrix which allows you to turn a
matrix of 3D coordinates into an im3d image object.
ind2coord(inds, ...)
# S3 method for default
ind2coord(inds, dims, voxdims, origin, ...)
# S3 method for array
ind2coord(inds, voxdims = NULL, origin = NULL, ...)
# S3 method for im3d
ind2coord(inds, voxdims = NULL, origin = NULL, ...)indices into an image array (either 1D, for which dims
must be present, or a logical array).
extra arguments passed to methods.
dimensions of 3D image array.
vector of 3 voxel dimensions (width, height, depth).
the origin.
