In Virtual Reality (VR), degrees of freedom (DOF) describe how rigid bodies move in 3D space. VR has translational (x, y, z) and rotational (pitch, yaw, roll) DOF.
If only translational movements are present, it’s three degrees of freedom (3DOF).
If both translational and rotational movements are involved, it’s six degrees of freedom (6DOF).
Applied features of 3DOF and 6DOF
Let us look at how 3DOF and 6DOF enable various features in specific applications
