I’m from Taiwan .
You can just call me Johnny.
I’m a PHD student and major in sports biomechanics.
My interesting topic is baseball pitching and batting.
I hope AnyBody can help me to do some studies, like upper and lower
extremity muscle simulation in baseball.
I collect the motion and force plate data for baseball players.
But I still have no ideal how to use the AnyScript to drive those
data.
I hope I can learn from you all and figure out how to solve the
problem from this Group.
Does anyone have the processes to drive the AnyBody human model by
using c3d file (VICON)?
Could you teach me how to use c3d file to drive the model step by
step?
Lots of models are driven by mocap data. You can learn the basic idea
of this in the following tutorial http://www.anybodytech.com/677.0.html . If you have a c3d file you
can covert it using the converter c3d2any.exe that you can download
here http://www.anybodytech.com/116.0.html?&tx_ttnews[tt_news]
=46&tx_ttnews[backPid]=37&cHash=7edc0e828c . This automatically
creates anyscript files with the markers and their trajectory. Then
you have to link the markers to the model either manually of
automatically with the new application called GaitApplication2.exe
that you can download in the file section of the group.
This application helps you driving a model with markers. It is more
efficient because it creates automatically drivers to fit the best
possible the markers trajectory. But this is only for the lower body
(legs and pelvis). As you are interested in baseball player you need
a full body model I think, for a player striking the ball for
example. So in a first time you would have to take a full body model
and only drive the lower body with the GaitApplication2 and keep the
upper body rigid.
To do so you can look at the model GaitUniMiami, all the steps to use
the application are described at the top of the main file.
Once you have the lower body moving you can drive the upper body
using the manual method. The idea is to use the same kind of driver
as in the tutorial between a moving marker and a marker on the body.
You can use the drivers from the WheelChairRancho model as an
example. Please follow those steps:
include the set of body markers for both side
adjust the initial position so that the body is close to the
moving markers
replace the existing joints angle driver by the linear marker
driver from WheelChairRancho one at a time and make sure to keep the
model running after each replacement
if the new drivers fail try improving the initial position of
the body
