PLY: binary export
Thanks to Adrian Vogelsgesang (@vogelsgesang) and his binary ply export
implementation proposal D4252.
I did not reuse any code from his patch, but it gave me a good starting point
as I had no idea how to work with binary data.
In this commit:
* Implement export to binary little-endian file format.
* Remove information about blend filename from exported file, it has no purpose.
* Binary is the default format from now on.
I cannot see any reason to implement big-endian option, if there is, please let me know.
Below you will find performance comparison between ASCII and binary formats.
Test geometry:
* Verts 379 000
* Faces 378 000
Export:
* ASCII (old) 8.0 sec
* ASCII 3.0 sec
* Binary 2.4 sec
Note: difference between old and new ASCII export is due to avoiding
unnecessary normal claculation when export normals is disabled.
Import:
ASCII 5.75 sec
Binary 4.9 sec
File sizes:
* ASCII 20.6 MB
* Binary 10.4 MB
