[x3d-public] Humanoids+Dynamics

Mon Jan 23 11:15:41 PST 2023

Good ideas.  If you look for projects doing that, we can next look for
export/import.

The path to new capabilities passes through more examples showing off and
testing our current capabilities.

all the best, Don

Subject: [x3d-public] Humanoids+Dynamics

I'm thinking we don't want all of one's humanoids doing the same walk, run,
jump, etc.   so there should be some way to add variety to any animation
provided to humanoids.  I'm guessing this is highlighted in animation video
and is probably implemented through some kind of physics, I'm not sure if
there is HumanoidPhysics yet beyond motion.   This reminds me of when i saw
the first demos of adding dynamics to humanoids.

Would it be appropriate to add dynamics or inverse kinematics to HAnim V3?
Based on state of humanoid.

Web3D x3d forums are mainly standards-track based. Questions to and from
authors and implementers with several specialty lists. .  

For instance for HAnim, a Standards-track main idea to implement best
practice for certain sets of features of certain fidelity for related data
sets. For instance the skeleton is realistic with set of Joint names is
intended to match Medical usage. The set of surface feature Site locations
are named for measured landmarks used in various national and international
standards. There is a certain pose prior to animation. These are intended as
a baseline for being a "Standard" Humanoid. 

The main documentation for our x3d HAnimHumanoid is xml schema and object
model standards that allow, for instance, a user to declare that the model
is an official 'Standard' Humanoid because it includes a validated hierarchy
structure and a 'Standard' set of names. Or, that it is different than the
official 'Standard' model. 

Measurement details are not part of the spec but human-scale measurements
are recommended. 

X3D HAnim documents this standardized structure with tools to extend this
basic,  transportable, reusable model to whatever it takes for best result. 

More animated Joint objects? More interactive feature points? Special
accessories? Scripted behaviors? Different names? All are your choice to
document your 'Standard' model(s) and extend, with validation, as you wish. 

Supporting x3d schema is open with many open authoring and validation tools.

Delivery based on best interactive realtime tools of WWW.

All good, 

Joe

*	What forums on x3d and programming topics have very fast answers
besides stackoverflow? 

Well, what is the question? If it  is about X3D,, except for specialized
questions best handled by dedicated working groups, most can be answered
here. 

*	: forums for engines like Unity, fast scenes, cartoons? 

If you wish to supply 3D for the web and are truly interested in innovations
to postings and commentary  using the internet, then use an engine aimed at
realtime anytime interactive shared or private best practice 3d engine aimed
directly at our world wild web. Author a realistic or not character for
yourself and create or import into your or their environments. Know that
sooner or later, if you are having fun, then you will want to look at and
edit details of the user code, and even examine and edit runtime results.

Plus, x3d is for free.

Base you selection on its support for the close to the metal data structures
as well as human-readable user code backed by World-standard syntax and
conformance details. There exists many ways to draw stuff and structure the
data encoding your interface with yours and others. Then when you want to
publish to WWW then you want to use the standard. Using an x3d-based engines
(yes, multiple x3d engines available) you can publish using instruments
based on realtime or engines mainly intended for making videos. You can
always build a walled garden using a proprietary set of tools, but think, if
you want to be open then you choose open tools. 

Also, under the covers, all the data for things and events is the same, only
the names are changed to protect autonomy, function, purpose, and
application of the data structures. 

Have some fun with realtime interactive 3D. Some call it 4D, meaning
animation in spacetime, and that is fine, but X3D with its proven and robust
data environment is really nD+1.  The more you look, the more you will find.

Hi

What forums on x3d and programming topics have very fast answers besides
stackoverflow? 

Also good if they have another topics

Also what's best systems and forums for engines like Unity, fast scenes,
cartoons?
