Six degrees of freedom (6DoF) refers to six independent motions of a rigid body in 3D space. They consist of three translations along the , , and axes and three rotations around those axes, , , and . 6DoF is a fundamental concept for mechanical, aeronautical, and robotics engineering. This Demonstration lets you interactively control a model with 6DoF, or you can choose the randomize option to visualize motion with multiple DoF combinations. (Select the "randomize" checkbox to toggle between random and manual control mode. )
