  1. Assignment 2Part 1 Help Note by TA

  2. Bodypart – 人體骨架的基本單位，用來繪製joint與bone用 • Posture – 儲存一個frame的資料 • Motion – 儲存一整個motion的資料

  3. BVHloader.cpp • BodyPart::Draw(Posture* pose) • 把一個frame的資料餵進來， • 利用那些資料來繪製關節點與骨頭 • 然後recursively去繪製它的子關節 • BodyPart::UpdateGlobal(Posture* pose) • 在寫第二部分時才會需要呼叫 • 你會需要知道右手拳頭的global position

  4. Motion.cpp • Motion::Load(string name) • 打開bvh檔 • 一次讀一行 • 先建立骨架 • 呼叫 Motion::GenerateSkelton() • 讀frame數 &Sampling rate • 再讀motion data • 每一行呼叫一次 Motion::AddFrameData()

  5. Motion.cpp • Motion::GenerateSkelton(ifstream &inFile, BodyPart *node, BodyPart *prevNode) • 讀一個 joint/end site 的資訊 • OFFSET • Channel • 建立hierarchical 的骨架結構，並遞迴呼叫GenerateSkelton()

  6. Motion.cpp • Motion::AddFrameData(ifstream &inFile, BodyPart *node, int index) • 根據channel數量來讀入若干筆資料 • 注意尤拉角的順序 • 遞迴呼叫AddFrameData，丟入這個關節點的下一個子關節點(node->GetNextBodyPart(i))

  7. Motion.cpp • Motion::IK() • 第二部分才會需要呼叫 • Motion::BuildIKtree(Posture& p) • 第二部分才會需要呼叫
