WebMar 5, 2024 · My purpose is to rotate the field from the "antenna" reference system (where a phased array lies on the XoY plane) to the "measurement" reference system (where the phased array is rotate and now is "vertical", i.e. on the YoZ plane). So in the first case I expect the main lobe on the z-axis, while in the second along the x-axis. WebMay 9, 2024 · If euler rotation is used and you want the quaternion rotation you can use to_quaternion () to convert it. Quaternion values also have to_axis_angle () and to_euler () if you need to convert the other way. The mathutils module contains some extras. WebAug 1, 2024 · It does not really make any sense to ask for the angle of rotation "on the x axis". The easiest way to find the angle is to use the formula. 1 + 2 cos θ = t r a c e ( Q) , where t r a c e ( Q) means the sum of the diagonal elements of Q. In this case. t r a c e ( Q) = 0.36 + 0.60 + 0.60 . You can find the axis from the fact that it is an ... how were metals used in the past
