utils.box orientation not used in code

[Alexander Eulitz [Eugen]]

Working on Christian Jakobs performance script published int he wiki[1] Christian and I recognized that the orientation quaternion used as third parameter of utils.box[2] is not used at all in the code.
According to Christian this must be due to a change in code that happened in the last months, because his script worked will before.
How can you know include a box that is rotated by a given angle around an axis?

I am not sure about this, maybe I used a facet for the screenshot at that time ...

Nevertheless I have to update the wiki page.

As far as I know it is not possible to rotate boxes.

Although "orientation" parameter is in utils.box, it is really not used there.
You can use geom.facetBox, which respects "orientation"-parameter.

ok, that will do.

q=Quaternion()
q.setFromTwoVectors((1,1,0),(1,0,0))
b.state.ori=q

Thank you for reporting this bug. I fixed it in 6279eb1.
So this will do exactly the same as above:

box((0,0,0),(1,0.1,0.1),orientation=q))

thats even better! Thanks a lot
