Muscle deformation

Hey guys,

I’m a born perfectionist, and that’s no good because there’s no such thing as perfection in a world such as this. A world of change, decay and chaos.

However, I’m curious to know if in CG, it’s actually possible to reproduce the muscles deformations of the human body with 100% of accuracy.

I was thinking about that and I concluded it would be an almost impossible task to accomplish because the deformations of the muscles in the body are extremely complex and unpredictable in it’s details. They can deform in almost infinite ways depending on the position of the body and it’s parts, and they’re also affected buy gravity and other things.

So, to me, making a model that you could pose and animate with 100% a accuracy in all of its forms would be nearly impossible.

I think that the only way such thing could be achieved in CG would be to scan a real person in all poses possible (like many thousands of slightly different poses) and then combine all the data together in order to create an ultra accurate human body muscle deformation.

So what do you think? Have you ever thought about how accurate muscle deformation in a CG model can get?

CG has come a long way with accuracy in things. I guess it depends on what route one would take to approaching “recreating reality”. Either by improving scanning and motion capture technology and basing future 3d tools off what we “observe” from reality. Or improving the math/physics behind the 3d tools to more accurately “predict” reality. Or both. I think it’s possible to reach at least up in the 90’s percentage range of accuracy with the tech we have.

CG is being used more and more these days for calculating things like the physics of objects reacting with each other, for building products, 3d for medical also keeps improving. I think the continuing of improving computer power and ability to calculate how things react in real life, the possibilities are virtually endless, even 100% prediction or close to it.

I worked for a couple physical therapists for a job once. One of the projects they had me work on was recreating all the target muscles of the human body in 3d. I didn’t have to rig them to move, but ended up doing a lot of research, pouring over medical books and articles learning how muscles are layered and react with different movements a person exerts, how much stress certain body parts can take. There is a lot of info out there we now have.

I think it’s possible to accurately predict movement, the more understanding we gain from real life. At least for now though, it can be tremendously difficult to get to the 100% mark. I’m not as directly involved in the 3d industry anymore so someone else might have a better grasp.
