• PLYファイルフォーマット binary little endian

[Indigo2233]

I use this for binary .ply file:

    let ply_file = if fmt == "bin" {
        let mut lines = BufReader::new(File::open(path).unwrap());
        let mut lines_v = vec![];
        loop {
            let mut line = "".to_owned();
            lines.read_line(&mut line).unwrap();
            if line == "end_header\n" { break; }
            lines_v.push(line.trim_end().to_owned());
        }
        lines_v.push("end_header".to_owned());

        let mut buf = vec![];
        lines.read_to_end(&mut buf).unwrap();
        lines_v.push(unsafe { String::from_utf8_unchecked(buf) });
        PLYFile::from_lines(&mut lines_v.into_iter())
    } else {
        PLYFile::from_file(path).unwrap()
    };
