Left-handed coordinates to right-handed coordinates

Hi there,

I am inventorying ways to convert positions, rotations, and scale transformations from the Unity 3D coordinate system to a right handed coordinate system (e.g. Open GL).

Here's a very useful resource I found : Conversion of Left-Handed Coordinates to Right-Handed Coordinates.

However I would like to know if it already exists such functionality in the Unity 3D API, or If you have other solutions to propose.

Thank you.
