I mounted an IMU on a drone which collected quaternion data (w,x,y,z) every 0.1s. Now I want to compare the quaternion data to the actual drone orientation (video data). So I would like to create some sort of box object that shows the orientation based on the quaternion data. I implemented this tutorial which converts the quaternions to Euler for visualization. Is there a way to directly visualize quaternion data, without converting it to Euler first? I feel like this should be possible, but I am not sure how. Continue reading...
