769892 - 3D transform rotate3d from -90deg to -180deg goes through 270deg

Status: RESOLVED WORKSFORME

(Core :: CSS Parsing and Computation, defect)

Description

[Phil Parsons]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.4 Safari/537.1

Steps to reproduce:

Transitioned the transform on a 3D box that is set at rotate3d(1,0,0,-90deg) to rotate3d(1,0,0,-180deg).

See:
http://jsbin.com/iwokok/8 (rotate3d(1,0,0,-90deg) to rotate3d(1,0,0,-180deg))
http://jsbin.com/iwokok/9 (rotate3d(1,0,0,180deg) to rotate3d(1,0,0,270deg))
http://jsbin.com/iwokok/11 (rotate3d(-1,0,0,90deg) to rotate3d(-1,0,0,180deg))


Actual results:

The transition animates the box through 270deg in the opposite direction. This also happens from rotate3d(1,0,0,180deg) to rotate3d(1,0,0,270deg)—the same face in the opposite direction.


Expected results:

The box should animate to the new transform through 90deg.

If nobody else wants this I'll grab it.

Yes rotate3d is not working correctly as Phil reported. 
This bug for the moment can be avoid by using rotateX, rotateY, and rotateZ where the rotation works correctly.

Sorry,Please interpret "Good" of comment 3 as follows,
Good: rotate 90deg, but direction is wrong( rotate opposite direction )

Comment 5

+1. I just burned two hours on this before finding the rotateZ solution.

Comment 7

[Hiroyuki Ikezoe (:hiro)]

Is this still an issue? All test cases in comment 0 seem to animate through the shortest path.

Comment 8

[Karl Dubost💡 :karlcow]

This seems to be fixed indeed.
