Itâs a generic question, Iâm using Blender to learn figure drawing and want to know if there are any tools that allow one to access that real world balance of any pose!
I donât have knowledge of specific resources in Blender that would solve that right away.
But through your question, I can conceive the certain uses of Physics in Blender, in order to try to simulate a generic Gravity pull on different points/volumes of interest (with manually set, different Mass inputs), inside an Object.
For example, the free Wiggle 2 Addon (for later versions of Blender), for each âWiggle Boneâ that is Enabled to work with this Addonâs Physics inputs, can hold special settings for âGravityâ but also for âMassâ
In this way, it might be plausible to create a âGhost/Fake Skeletonâ (an Armature Object), which purpose is not for Rigging, but just for calculating the amount of âgravity pullâ over time (by playing the Timeline) for each relevant part of the characterâs Body Model.
However, that approach would be experimental, and might be challenging if ever useful; but it seems at least plausible to me, that something can be achieved: one primordial step would be the âgravity pullâ differentiate outputs by the setup on the Bones (in this Wiggle 2 Addon example), another step would be some sort of Automation⌠which might be much, much harder than just having the software giving some maths or visual outputs.
More thought would be required; but itâs an interesting question.
You should check some Blender tutorial ideas on Youtube, about âRag Doll Rigâ, I believe this can give you some insight; it uses in-built Physics.
Funny as this is, there are plenty of people who wonât be able to do it for a variety of reasons, including having drastically different body shape and/or physical abilities from the person being depicted. Itâs a legit question.
Hence my comment about a nude posed photo. Thereâs no âtrickâ or mathematical simulation for this, every body is different and thereâs simply no way to say if a certain mesh can pose in a certain way. If a photo can do it and your mesh has a similar body to the photo, it probably works.
Fat distribution, body fat percentage, muscle tone, athletic training, balancing ability, proportions, foot size, mood, anxiety levels, and even inner ear sensitivity all affect this- these arenât variables that can be plugged into an equation, itâs just too individualized and complex.
I think the best example of this is the Olympic womenâs gymnastics beam finals- those gymnasts did poses none of us could do without falling during warm-ups, but they all whiffed their balance on the beam due to nerves. Thatâs not something that can be mathematically accounted for
Yeah, I did actually have that in mind at the time I posted and sure, if your character is a near super human ninja, then no doubt many of us would have problems replicating the move. Still, itâs worth a basic try (if you can) to get some idea of how the pose feels.
I can even give a direct example. When I was blocking my little test animation for my Nyssa character, I had the hand pull down the blind how I thought it would.
I then actually went to try and do it myself and without thinking about it, actually had my hand 180 around the other way.
