Viewer technically records the data into the .bag file. No options for csv or similar. Better to code it. We have a sample available here: dev.intelrealsense.com/docs/rs-pose
Don't buy this crap 3D camera ! This viewer failed each time that i try to switch on the RGB Camera. 200€ for a 4 years old technologie which doesn't work properly in their own software?! What a waste of money...
