introduction
Introduction
  • What is “Computer Graphics”
    • 簡稱CG
    • 利用數學演算法在電腦上顯示出擬真的影像
  • Where is “Computer Graphics”
    • Entertainment:Movie、Game、Design
    • Animation-pre-computing
    • Virtual Reality-real time
  • How to use “Computer Graphics”
    • Graphic Library:DirectX 、 OpenGL
    • Programming Language :C++、 VRML
computer animation
Computer Animation
  • 預先以大量的電腦(render farm)運算出high quality的影像(frame),聯接成動畫(animation)
    • 視覺殘留
    • minimal-12 fps (frame per second)
    • cartoon-15 fps
    • ordinary movie-24 fps
  • Render farm
    • Parallel computing
    • 鐵達尼使用上千台workstation
    • Ice age使用512台workstation
    • 立德校園動畫使用50台PC
