Statistical Scaling Plugin

Plugin for scaling subjects based on an anthropometric database.

This example shows how to use the Statistical Scaling Plugin. The plugin is a small app which allows you to simply specify a few anatomical or functional parameters when scaling the model. The plugin calculates the remaining (free) anthropometric variables based on the ANSUR 1 anthropometrical database.

The big advantage is that the correlation between variables are maintained, so the model will have realistic anthropometrical dimension as long as the constraints does not conflict (e.g. a very high stature with very short legs )


The algorithm used by the plugin is based on principal component analysis (PCA) of the correlations between variables in the anthropometric database. An optimization problem is then solved minimizing the normalized principal component subject to the anthropometricall constraintsngiven by the user. Please see:

The plugin can not be used to generate subjects which are very different from the population of the ANSUR database. For example children.

Use the plugin in other models

The plugin can be used in any model as long as it uses the _SCALING_XYZ_ scaling law. It is also necessary to specify into which file the plugin should write the calculated anthropometrics. This is done by setting #path ANSUR_PLUGIN_ANYMAN_FILE model file which contains the anthropometrics .


#include "<ANYBODY_PATH_AMMR>/Tools/Plugins/ANSUR_Plugin.any"
#path ANSUR_PLUGIN_ANYMAN_FILE "anthropometrics.any"

// Ensure that the generated anthropometrics are
#include "anthropometrics.any"
