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
-}
