Compute visual hull — optional

Parameters

occupancy	output visual hull. occupied or not
dx	longest bounding box depends on resolution; dx = bounding_length_max / (float)(resolution - 1);
Nx	X grid length; Nx = (int)((bounding_box_length_X) / dx) + 1;
Ny	Y grid length; Ny = (int)((bounding_box_length_X) / dx) + 1;
Nz	Z grid length; Nz = (int)((bounding_box_length_X) / dx) + 1;
minx	min x value in bounding box
miny	min y value in bounding box
minz	min z value in bounding box
numCam	number of cameras
width	image width
height	image height
R	rotation matrix of all cameras
T	translation matrix of all cameras
K	intrinsic parameters of all cameras
img	data of all images
