Additional properties to the PLY format

[rwmontalvao]

First, thank you for this code. It is valuable for my work on bioinformatics. Some of the PLY I work with have crucial chemical information. For example:

ply
format ascii 1.0
comment Generated by PyMesh
element vertex 10146
property float x
property float y
property float z
property float iface
property float charge
property float hbond
property float hphob
property float nx
property float ny
property float nz
element face 20312
property list uchar int vertex_indices
end_header

Is it too complex to modify the PLY parser to include additional properties?

It's shouldn't be too difficult to include. If you want to try, you'd have to modify https://github.com/JuliaIO/MeshIO.jl/blob/master/src/io/ply.jl

You can add per-vertex data to the mesh by passing it as a kwarg:

charges = [...]
Mesh(points, faces; ..., charge = charges)

Other data can be included in a MetaMesh:

bonds = [1 => 2, ...]
MetaMesh(Mesh(...); bonds = bonds)

You can check the obj loader for reference.

@ffreyer thank you. I will try it.
