Sets the native angle units (radians or degrees) expected by and returned by the <a class="el" href="namespaceOgre.html">Ogre</a> API.
<p>
<dl compact><dt><b>
Remarks: </b><dd>
By default, OGRE's main API uses degrees (this <a class="el" href="classOgre_1_1Math.html">Math</a> class uses radians because that is the underlying unit used by the library routines. This may be changed by the user of the engine so that every instance of degrees actually accepts radians instead.
<p>
You can set this directly after creating a new <a class="el" href="classOgre_1_1Root.html">Root</a>, and also before/after resource creation, depending on whether you want the change to affect resource files.
<p>
Warning: don't set this during the middle of an app run - some classes store degrees internally as degrees, and perform the conversion for internal usage. Changing the AngleUnits between set and get will result in screwed up values. This affects some file loading too - notably particle system angle attributes. These values must also be changed in the particle files to use radians. </dl>
