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
extra arguments passed to methods.
dimensions of 3D image array.
vector of 3 voxel dimensions (width, height, depth).
