Hi all,

I convert my quaternion to a matrix using left handed coord system.

I have an input who is right handed, so the rotation needs to be inverted on each axis.

When I input my quaternion, if I change w to -w it's ok, inverted axis works too.

What is the more correct, invert the w or invert (x,y,z) ?

Thanks

Hi all,

I convert my quaternion to a matrix using left handed coord system.

I have an input who is right handed, so on the X-axis my rotation need to be inverted.

When I input my quaternion, if I change w to -w, inverted axis work too.

What is the more correct, invert the w or invert (x,y,z) ?
