GLM_FORCE_RADIANS has no effect on glm::perspective about glm HOT 3 CLOSED

It seems GLM_FORCE_RADIANS is used in all the other perspective* functions (perspectiveFov, infinitePerspective, tweakedInfinitePerspective) but oddly is ignored in glm::perspective().

This bug is now fixed on GLM 0.9.4 branch. Thanks for reporting!

Happy new year to you too!

I just did another pull of recent changes and the commit to fix this introduces another bug. In the case where GLM_FORCE_RADIANS is undefined, you are doing this:

valType const rad = glm::radians(fov);

But then in the next line you are doing another degrees-to-radians with

valType range = tan(radians(rad / valType(2))) * zNear;

What you want is

valType range = tan(rad / valType(2)) * zNear;
