Question

I have a small obj loader and it takes two parameters and passes them back to the input variables.. however this is my first time doing this and i\'m not sure how to print s

Answer 1

To get the overload resolution right, you can do something like:

// Writes a generic GLM vector type to a stream.
template 
std::ostream &operator<<(std::ostream &os, glm::vec v) {
  return os << glm::to_string(v);
}
