Hello, is it possible to rotate a box around 2 axes separately by using the VR sink in Simulink? Because its just possible to have one input with the angle and one rotation axis. Thanks!

In order to rotate an object around 2 axes separately, use euler angles and convert 2 axes rotation into one quaternion and then provide this axis input to the VR Sink.
eul = [0 pi/2 0];
qZYX = eul2quat(eul);
Take the last three values of qZYX and provide them as axes for the VR Sink. Note that default order is ZYX for this function. so [0 pi/2 0] means 0 in Z, 90 is Y and 0 in X.

Hi Mandar,
I have one additional Question. If i have the passed Angle over time (in Rad) by two axes (x and y axis). I can directly go into eul=[0 passed Angle-Y passed Angle-X]; and use eul2quat(eul) afterwards and send it into vrsink. The problem is it looks kinda strange but your explanation seems really simple.
