~~Title: Efl.Gfx.Mapping.rotate_quat_absolute~~
====== Efl.Gfx.Mapping.rotate_quat_absolute ======

===== Description =====

%%Rotate the object in 3D using a unit quaternion, using absolute coordinates.%%

%%This is similar to %%[[:develop:api:efl:gfx:mapping:method:rotate_3d|Efl.Gfx.Mapping.rotate_3d]]%% but uses a unit quaternion (also known as versor) rather than a direct angle-based rotation around a center point. Use this to avoid gimbal locks.%%

%%The coordinates of the center point are given in absolute canvas coordinates. See also %%[[:develop:api:efl:gfx:mapping:method:rotate_quat|Efl.Gfx.Mapping.rotate_quat]]%% for a pivot-based 3D rotation.%%
