Construct a packed volumetric feature space

Usage

volume_space(
  dim,
  affine = diag(4),
  support = NULL,
  template = NULL,
  units = "mm",
  metadata = list()
)

Arguments

dim: Three spatial dimensions.
affine: A 4 by 4 voxel-to-world affine.
support: Logical full-volume support or packed linear indices.
template: Optional template/native-space identity.
units: Spatial units.
metadata: Additional serializable metadata.

Value

A volume_space.

volume_space(c(2, 2, 2), affine = diag(4), support = 1:4)
