Rigid body dynamics is a type of motion or animation system in which the sections of model or avatar are treated as solid, rigid items ? they have no flex or give. In this way, the process of computing how they would react to a given force is greatly simplified.

Whilst over 30 years old now, this book is one of those whose usefulness is never likely to fade. It is a physics book, dealing with the mathematics and physical constraints of getting any rigid body jointed system to move as desired. Designed initially with robots in mind, long before the avatar, the maths contained within is ideal for grounding on ragdoll physics as used with avatars.
A worthwhile look at the benefits of using C++ over C for complex tasks, such as physics.
With the number of rubber body(part) studies that have been done, each showing that if it looks to be a body part, and feels like a body part, the brain accepts it as a body part, this research should also hold no surprises. We finally have direct proof of the concept that, when we utilize any tool, even for a scant few minutes, our brains integrate that tool into our self-body-image.
Rubber hand, rubber body, rubber arm, rubber leg. Time and time again, studies have shown that even if a body part is completely fake, completely artificial, if enough of our senses tell us that it is us, then we believe it, consciously and subconsciously. This can easily be exploited by VR, such that what you perceive to be your body, IS your body, even when its really your avatar.
A detailed and in-depth article by the singularity hub, on the quest for integrating the human body with a sensory network, and what such will mean for us as individuals, health and life-wise.
In order to link a mind to a virtual body, which will be controlled by the same subconscious and conscious impulses as a physical body should be, the link connecting the mind to the physical body, save for autonomous finctions, is likely to require severing or blocking for the duration of the virtual immersion.
ED-209 is the classic example of the programmed mind problem. When you program a mind how to think and what to think, as opposed to letting it evolve its own reactions with guidance and teaching, you create a rigid and inflexible will which simply cannot understand input outside its programmed range.
The brainstem is the part of the brain that descends just in front of the cerebellum. It drops down from the brain to meet and meld with the spinal cord rising from the body. The issue is, how do we go about hijacking the brainstem, to splice a virtual body, or artificial body parts onto it?
