      public static Buffer getBufferView(ByteBuffer source, int byteOffset, int count, int byteStride, int numComponents, VertexBuffer.Format originalFormat, VertexBuffer.Format targetFormat) throws IOException
      Try to expose a glTF buffer region as a typed NIO view without copying. Falls back to allocating a destination buffer and populating it when interleaving, normalization, or format mismatch prevents a pure view.
      Parameters:
      source - the original ByteBuffer (direct or heap)
      byteOffset - start offset within source (relative to beginning)
      count - number of elements
      byteStride - stride in bytes (0 means tightly packed = element size)
      numComponents - components per element (e.g. 3 for VEC3)
      originalFormat - the source component type
      targetFormat - the desired buffer view type to return
      Throws:
      IOException
