center3(
  tbl,
  at_x_ = NULL, at_y_ = NULL, at_z_ = NULL,
  x_ = x, y_ = y, z_ = z,
  use_bounding_box = TRUE,
  keep_bounding = TRUE
)

`tbl`	[tibble], a tibble containing points to be centered
`at_x_`	[numeric], length 1, default NULL, value by which to center `x` variable in `tbl` default behavior is to leave center unchanged
`at_y_`	[numeric], length 1, default NULL, value by which to center `y` variable in `tbl` default behavior is to leave center unchanged
`at_z_`	[numeric], length 1, default NULL, value by which to center `z` variable in `tbl` default behavior is to leave center unchanged
`x_`	[expr], variable name in `tbl` of `x` variable
`y_`	[expr], variable name in `tbl` of `y` variable
`z_`	[expr], variable name in `tbl` of `z` variable
`use_bounding_box`	[logical], length 1, default `TRUE`, if `FALSE` rotate3 does not use bounding box points to make computations default behavior is to use bounding box points to make computations
`keep_bounding`	[logical], length 1, default `TRUE`, if `FALSE` does not rbind the bounding box back after computation default behavior is to use bounding box points to make computations

tibble with values
x centered x coordinate
y centered y coordinate
z centered z coordinate
face is point part of "front", "back", "left", "right", "bottom" or "top" face
tb is point on "top", "middle", "bottom" side of face
rl is point on "right", "middle", "left" side of face
bounding_box if TRUE, point is part of bounding box
