Remarks

Collection of algorithms for smoothing bone weights. Bone weight data is fetched using the TBoneWeightsDataSource which is implemented by the caller to match their custom data storage of bone weights.

Example usage:

// Mesh whose bone weights we are smoothing FDynamicMesh SourceMesh = ... ;

// The caller should create a subclass of TBoneWeightsDataSource that implements its interface TUniquePtr DataSource = ... ;

// Setup the smoothing operator TSmoothBoneWeights SmoothBoneWeights(&SourceMesh, DataSource.Get());

// Array of vertex IDs to apply smoothing to TArray VerticesToSmooth = ... ;

// Run the operator const float SmoothStrength = 0.2; if (SmoothBoneWeights.Validate() == EOperationValidationResult::Ok) { for (const int32 VertexID : VerticesToSmooth) { TMap FinalWeights; SmoothBoneWeights.SmoothWeightsAtVertex(VertexID, SmoothStrength, FinalWeights); // Use FinalWeights to modify your weights } }
