There was a problem hiding this comment. This will be a good base to build on for pre-baked camera solutions as we make more comprehensive "out of the box" components! |

There was a problem hiding this comment. none of these comments are helpful are they? a parameter named screenSize is obviously the size of the screen - maybe give the units? |

There was a problem hiding this comment. other than the unhelpful docs, these are excellent - thanks for unifying the camera logic! |
