Compute boundary hull points in world space (C++)
Usage
compute_hull_world_cpp(vol, dims, grid2world, thresh, n_points, mask)
Arguments
- vol
flattened numeric array (dim = dims)
- dims
integer vector length 3 (nx, ny, nz)
- grid2world
4x4 matrix mapping voxel indices to world coords
- thresh
intensity threshold
- n_points
max number of hull points (approximate)
- mask
optional logical vector same length as vol; if empty, ignored
Value
numeric matrix (n_points x 3) of (x,y,z) in world coords
