The libE57 is okay but I have to try to do this without any library. I found presentation and there I found next:
Binary Encoding
Blobs :
Opaque encoding
Images, user-defined data ....
"Opaque encoding" means that I can't read .e57 without libE57?
Is there some way to parse it?
I have a parser for a .pcd, .pts, .ptx. Can I convert a .e57 to one of them?
No. You can read data of .e57 only using libe57.
