A wonderful script. I tried this by loading a .txt file, primarily so that I could accesses the [y][z] locations of each vertices.

in the case of the .ply file - how would you accesses the [y][z] positions of each point?

how would you accesses the [r][g][b] values of each point?

^ I was not able to figure out how to do this for a string .txt file but I was wondering if this was possible with your .ply method?

Best regards!
