Examples

# Create a simple 3D volume
bvol <- NeuroVol(array(0, c(10,10,10)), NeuroSpace(c(10,10,10), c(1,1,1)))
grid_coords <- matrix(c(1.5,1.5,1.5, 5.5,5.5,5.5), ncol=3, byrow=TRUE)
world <- grid_to_coord(bvol, grid_coords)
grid <- coord_to_grid(bvol, world)
all.equal(grid_coords, grid)
#> [1] TRUE
