Data Format Conversion Extension (NvBlastExtConverterLL)

The low-level converter extension is a utility to convert NvBlastAsset and NvBlastFamily data from one format to another.

+The format version of an asset may be obtained using the function

uint32_t assetVersion = NvBlastAssetGetFormatVersion(asset, logFn);
+

+and likewise the format version of a family may be obtained using the function

uint32_t familyVersion = NvBlastAssetGetFormatVersion(family, logFn);
+

+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.

+To apply it, simply use the function convertDataBlock. For example, given an asset pointer,

vector<char> inBlock, outBlock;
+
+inBlock.resize( NvBlastAssetGetSize(asset), logFn );
+memcpy( inBlock.data(), asset, NvBlastAssetGetSize(asset) );
+
+if ( convertDataBlock(outBlock, inBlock) )
+{
+    NvBlastAsset* convertedAsset = outBlock.data();
+
+    // Use convertedAsset here
+}
+
