  /**
   * Calculate the 3D rope index based on image and video's temporal, height and width in LLM.
   *
   * Explanation:
   *     Each embedding sequence contains vision embedding and text embedding or just contains text embedding.
   *
   *     For pure text embedding sequence, the rotary position embedding has no difference with mordern LLMs.
   *     Examples:
   *         input_ids: [T T T T T], here T is for text.
   *         temporal position_ids: [0, 1, 2, 3, 4]
   *         height position_ids: [0, 1, 2, 3, 4]
   *         width position_ids: [0, 1, 2, 3, 4]
   *
   *     For vision and text embedding sequence, we calculate 3D rotary position embedding for vision part
   *     and 1D rotary position embeddin for text part.
   *     Examples:
   *         Assume we have a video input with 3 temporal patches, 2 height patches and 2 width patches.
   *         input_ids: [V V V V V V V V V V V V T T T T T], here V is for vision.
