function parseString seemed to not increment token after it used strspn to get the length of the whitespace characters at the beginning of token. So strcspn called right after that would return 0 and the created string would be an empty string.
Seems to have been working so far since it gets passed strings that don't begin with whitespace characters.
+ Added a LoadObj function that reads from a std::istream. This should allow
more generic usage and possibly make testing a little easier.
o This LoadObj accepts a function that returns a
std::unique_ptr<std::istream> for a material.
+ Modified LoadMtl to read from a std::istream to allow more generic
usage.
+ Modified test.cc to check that the changes work as expected and nothing was
broken.
Tests:
+ Compiled test.cc, checked diff of output against pre change output.
Same output where expected.
variables should be passed by reference.
They are passed by value. It could be passed as a (const) reference which is usually faster and recommended in C++.
This gives a 9% performance boost in my project.
