Mirror points or neurons in fish2 space

Source: R/xform.R
mirror_fish.Rd

mirror_fish mirrors objects with 3D vertices calibrated in nanometres across the fish2 midline using a thin plate spline registration derived from Philipp Schlegel's navis-fishbrains landmarks.

fish2_mirror_reg is the underlying tpsreg registration object for mirroring.

Usage

mirror_fish(x, ...)

fish2_mirror_reg

Format

fish2_mirror_reg is a tpsreg/reglist object.

An object of class tpsreg of length 2.

Arguments

x

Any object with 3D vertices (calibrated in nm), e.g. a neuron, a neuronlist, a mesh, or a 3-column matrix / data frame of points.

...

Additional arguments passed to xform_brain.

Value

mirror_fish returns the mirrored object.

Details

fish2_mirror_reg is shipped with the package and added to the nat.templatebrains registry on package load by fish_register_xforms, so calling mirror_fish normally needs no setup. See data-raw/fish2_mirror_reg.R for the construction recipe from the upstream navis-fishbrains landmark CSV.

Examples

if (FALSE) { # \dontrun{
library(nat)
# round-trip: mirroring twice should approximately recover the input
pts <- cbind(x = 500000, y = 400000, z = 150000)
mirror_fish(mirror_fish(pts))
} # }
