What is a One Unit Vector?
Although one unit vectors have no physical shape its good to conceptualize them as pointy thin things that are 1 meter in length. One unit vectors are used for specifying the orientation of something by pointing in a direction. A vector made up of 3 components x, y and z can represent any 3d orientation that exists. We can easily grasp what these 3 values mean if we think of a vector as always having its base at 0 0 0 like this we can think of the 3 components x, y and z equaling the location of the tip of the vector. What is an Axis? For vrml rotations we can think of the axis as a one unit vector where the pointy shape doubles as a spindle for any object we stick on it to be rotated. The spindle will never spin in a buckled manner. When it rotates it will always spin perfectly straight no matter what its orientation is set to. This means that the tip of the axis does not change location as a result of it spinning or what we change the angle component to. So a vrml rotation is pretty
