glm::euclidean
detail::tvec3< T, P > euclidean(detail::tvec2< T, P > const &polar)
Convert Polar to Euclidean coordinates.

glm::polar
detail::tvec3< T, P > polar(detail::tvec3< T, P > const &euclidean)
Convert Euclidean to Polar coordinates, x is the xz distance, y, the latitude and z the longitude...
