    I am hoping someone other there has already solved this problem.

    I have a cylinder I need to rotate. I need to calculate the number of total degrees the cylinder has rotated. As an example if the cylinder rotates 2 complete turns I need a value of 720 if it rotates in the opposite direction 2 complete turns I need a value of -720.

    Currently it seems the only values I can get from the get object rotation is : World Space 0 to 90 and then -90 to 0… and in local space I can only get values 0 to 180 and -180 to 0.

    I am hoping someone has worked out some logic or a method to calculate the total rotation?
    Given the cylinder can be rotated in either the postive or negative direction and will be controlled by a user so they may go back and forth quite a bit.

    Any help would be greatly appreciated.

    Hi xeon,

    Unfortunately the current way how the drag rotate puzzle works does not allow the user to capture the total amount of rotation. In fact it’s a fundamental limitation of how rotations are handled in Verge3D. We are using quaternions which do not preserve the information about previous rotation value. :-(
