<h1><a class="anchor" name="pageextconverterll">Data Format Conversion Extension (NvBlastExtConverterLL) </a></h1>The low-level converter extension is a utility to convert <a class="el" href="struct_nv_blast_asset.html">NvBlastAsset</a> and <a class="el" href="struct_nv_blast_family.html">NvBlastFamily</a> data from one format to another.<p>
The format version of an asset may be obtained using the function<p>
<div class="fragment"><pre class="fragment">uint32_t assetVersion = <a class="code" href="_nv_blast_8h.html#fa3dbe442bf799bbee07eb98774340d4">NvBlastAssetGetFormatVersion</a>(asset, logFn);
</pre></div><p>
and likewise the format version of a family may be obtained using the function<p>
<div class="fragment"><pre class="fragment">uint32_t familyVersion = <a class="code" href="_nv_blast_8h.html#fa3dbe442bf799bbee07eb98774340d4">NvBlastAssetGetFormatVersion</a>(family, logFn);
</pre></div><p>
If the format version does not match the SDK's current version for one of these objects, the data may not be used with the current SDK. The NvBlastExtConverterLL extension will apply a chain of conversion functions to transform an asset or family from its stored version to any other version, provided that such a chain exists.<p>
To apply it, simply use the function convertDataBlock. For example, given an asset pointer,<p>
<div class="fragment"><pre class="fragment">vector&lt;char&gt; inBlock, outBlock;

inBlock.resize( <a class="code" href="_nv_blast_8h.html#d7ee1d97ad6e4f048eab694249fa2594">NvBlastAssetGetSize</a>(asset), logFn );
memcpy( inBlock.data(), asset, <a class="code" href="_nv_blast_8h.html#d7ee1d97ad6e4f048eab694249fa2594">NvBlastAssetGetSize</a>(asset) );

<span class="keywordflow">if</span> ( <a class="code" href="namespace_nv_1_1_blast.html#d4349b26be7c27cd32db69e831d2248f">convertDataBlock</a>(outBlock, inBlock) )
{
    <a class="code" href="struct_nv_blast_asset.html">NvBlastAsset</a>* convertedAsset = outBlock.data();

    <span class="comment">// Use convertedAsset here</span>
}
</pre></div><p>
