[Bf-committers] [Bf-blender-cvs] SVN commit: /data/svn/bf-blender [24964] trunk/blender/source/blender/ editors/object/object_transform.c: Rename 'Object Center' to 'Centroid'.

[William Reynish]

Hi,

My problem with the word 'pivot' is that the objects origin may or may not be the pivot point in a transformation, and so referring to the object's (0,0,0) as the pivot point will often times be incorrect.

I actually think 'origin' is the best solution discussed so far. Yes, there's also a scene origin, but there's an origin for any level in the hierarchy. We could distinguish between the scene and object origins, just by using 'Scene Origin' and 'Object Origin'.

Cheers,

-W
