Tagging @rosecers , do you know how the rotation keyword is defined?

It appears that the rotation keyword refers to a rotation about the x, y, z view axis, where x=[1,0,0], y=[0,1,0], and z=[0,0,1] in euler angles with DEG unit.

That's correct!

The rotation key word indicates rotation about the x, y, and z axes, defined as the [100], [010], and [001], respectively.

Thank you for the confirmation @rosecers . I'm going to keep the issue open until this is actually implemented.

Since the glotzformats box is defined such that the first box vector must be parallel to [1,0,0], there is no way to actually rotate the whole system according to the specified rotation.

I'm currently working on an implementation where the rotation keyword is interpreted by the PosFileReader and the associated rotation is stored as a quaternion as part of the frame data. This rotation is also written out again by the PosFileWriter.

For this I copied and translated injavis code from java to python for the translation between the angles and quaternion and back. @rosecers, does the injavis license allow that?

I'm not entirely sure, that's a question for @michaelengel.
