rotation matrix : how does it work for flip? #23
Comments
My workaround for the moment : @ephtracy do you have the answer? |
one pose can be achieved by different transform sequences. |
hi, how can I parse rotation and scale (flip) from _r attribute? |
Hi there! Can someone please help me in separating the Rotation and flip values from each other? Thanks! |
I did this, but how do I figure out in which axis is the flip applied? And then How do I separate it? Thanks! |
Hi,
I just realised that both flip and rotation informations are in the rotation matrix (_r), but how does it work exactly?
How can I say when it is rotation or when it is flip? How can I know that there is a rotation and a flip at the same time?
Rotation and flip are two differents thing right? So I don't get why there is not two different attributes?
Exemple (based on datas collected from .vox file):
Rotation Z 90° :
0 -1 0
1 0 0
0 0 1
flip Y :
1 0 0
0 -1 0
0 0 1
Rotation Z 90° + flip Y :
0 -1 0
-1 0 0
0 0 1
So, from the last one, how can I extract the two first to apply them both?
