Comments

  1. If node_ID2 = 0 or node_ID3 = 0, Lines 4 and 5 are read.
  2. If node_ID2 ≠ 0 and node_ID3 ≠ 0, the frame is defined by three nodes like a moving frame. It is strictly attached to node_ID1 as its origin.
  3. If node_ID2 = 0 and node_ID3 = 0, the frame is defined by node_ID1 and its orientation is defined by two vectors ( Y ' and Z ' ), like a fixed frame.
  4. The frame translation and rotation depend only on the displacement and orientation of node_ID1.
