Hello,
Your project is very interesting,
I have compiled and ran, everything seems fine, but the output file 'options.txt.ply' is not empty but has no values with a point cloud.

this is a 'options.txt.ply' file:
ply
format ascii 1.0
element vertex 0
property float x
property float y
property float z
property float nx
property float ny
property float nz
property uchar diffuse_red
property uchar diffuse_green
property uchar diffuse_blue
end_header

I try to load this file to meshLab but this does not work.

this is the output in my terminal:
