Review of the first part of my approach to modelling basic perception: establishing a 3D framework

As a metaphor, we can think of the 3D framework as an invisible cage that the perceiver has built, and that turns and moves automatically with the perceived object.

• Note that we can construct this 3D framework with 2D vision, and even if we are standing on our head. In other words, this framework should be quite robust.

For the next part, we shall describe the perception of the major visible skeletal components of the actor or animal.
