Make sense?
Hobu,
Sure, it looks perfectly OK to me, except I would pass header by
const:
LASReader(std::istream& ifs, LASHeader const& header)
We can't pass it in const because the caller must be ready to have the
header's dataoffset change. We have to be able to change the
dataoffset or we won't be able to read points if the caller passed in
any old value.
I have made a pass at implementing this in main if you want to take a
look.
