/*! \page pageextapi Extensions (NvBlastExt)

These are the current Blast&tm; extensions:
<br>
<br>
\subpage pageextshaders - Standard damage shaders (radial, shear, line segment) which can be used in NvBlast and NvBlastTk damage functions.
<br>
<br>
\subpage pageextstress - A toolkit for performing stress calculations on low-level Blast&tm; actors, using a minimal API to assign masses and apply forces.  Does not use any external physics library.
<br>
<br>
\subpage pageextassetutils - NvBlastAsset utility functions.  Add world bonds, merge assets, and transform geometric data.
<br>
<br>
\subpage pageextauthoring - Powerful tools for cleaning and fracturing meshes using voronoi, clustered voronoi, and slicing methods.
<br>
<br>
\subpage pageextimport - Functions to import data from external formats and convert to a Blast&tm; asset.  Currently handles APEX NvDestructibleAsset data.
<br>
<br>
\subpage pageextexporter - Standard mesh and collision writer tools in fbx, obj, and json formats.
<br>
<br>
\subpage pageextserialization - Blast&tm; object serialization manager.  With the ExtTkSerialization and ExtPxSerialization extensions, can serialize assets for low-level, Tk, and ExtPhysX libraries
using a variety of encodings.  This extension comes with low-level serializers built-in.
<br>
<br>
\subpage pageexttkserialization - This module contains serializers for NvBlastTk objects.  Use in conjunction  with ExtSerialization.
<br>
<br>
\subpage pageextpxserialization - This module contains serializers for ExtPhysX objects.  Use in conjunction  with ExtSerialization.
<br>
<br>
\subpage pageextphysx - A reference implementation of a physics manager, using the PhysX&tm; SDK.  Creates and manages actors and joints, and handles impact damage and uses the stress solver (ExtStress) to
handle stress calculations.
<br>
<br>
To use them, include the appropriate headers in include/extensions (each extension will describe which headers are necessary),
and link to the desired NvBlastExt*{config}{arch} library in the lib folder.  Here, config is the usual DEBUG/CHECKED/PROFILE (or nothing for release),
and {arch} distinguishes achitecture, if needed (such as _x86 or _x64).
