visual hall

Thank you for your great work!
When I execute visual_hall.py, I visualize the result, but I find that the result is not a shell, but solid, why is that?

The expected output of the visual hull is a point cloud, not a shell. The visual hull is constructed by initializing a point cloud in space and removing points that fall outside the mask. As a result, it’s normal to see a solid structure at this stage. During further optimization, the point cloud will improve. Additionally, increasing the number of input views will enhance the quality of the visual hull.
