      • setPositionsAt

        public void setPositionsAt​(@NonNull
                           Engine engine,
                           @IntRange(from=0L)
                           int targetIndex,
                           @NonNull
                           float[] positions,
                           @IntRange(from=0L,to=125L)
                           int count)
        Updates float4 positions for the given morph target.
        Parameters:
        engine - Engine instance
        targetIndex - The index of morph target to be updated
        positions - An array with at least count*4 floats
        count - Number of float4 vectors in positions to be consumed

      • setTangentsAt

        public void setTangentsAt​(@NonNull
                          Engine engine,
                          @IntRange(from=0L)
                          int targetIndex,
                          @NonNull
                          short[] tangents,
                          @IntRange(from=0L,to=125L)
                          int count)
        Updates tangents for the given morph target. These quaternions must be represented as signed shorts, where real numbers in the [-1,+1] range multiplied by 32767.
        Parameters:
        engine - Engine instance
        targetIndex - The index of morph target to be updated
        tangents - An array with at least "count*4" shorts
        count - number of short4 quaternions in tangents
