  • Pen and Ink
  • Cel-look, cel-shading
motivation
Motivation
  • NPR is slow for real-time rendering.
  • So we decided to render it slowly and make it a clip of animation.
  • And we love Starcraft! (Don’t tell me you’ve never heard of it!)
  • Then we got a cool idea: remake a piece of classical animation in Starcraft with new(cute, cartoon) modeling , and of course in NPR cartoon effects!
  • Isn’t that funny?

Progress
cartoon rendering
Cartoon Rendering
  • Def : Contour Line & Discrete Shading
  • Focus : Contour(Silhouette) & Shading
  • Line by Object
  • Shading by Light
contour
Contour
  • Def: Line between front face & back face.
  • Char: Frame Coherence & Line Continuity.
  • Method:
    • Brute Force.
    • Geometry Division.
    • Modified Appel’s Algorithm
  • Special: Perlin Noise Function.
shading
Shading
  • Method:
    • Angle between normal vector & light source.
    • Shading table.
    • Modified interpolation.
    • Shading mapping.
animation production reproduction
Animation: Production&Reproduction
  • Animation Design Focus:
    • Pre process Settings:
      • Original Video Animation (OVA)
      • Script & Tran Script
    • Post process Production:
      • Determine the Stage
      • Model Design
      • Camera Tran Script
      • Light Settings
  • Difference /w Reproduction(Re’,always easier)
reproduction design focus
Reproduction Design Focus:
  • Precise Section Analysis
    • Fade in/out, Section Time Line, Determine object movement
    • Guess the Positioning of the Stage
    • True or False?(Not exactly, but still correct)
  • Real Working
    • Design Models for Replacing Original Ones.
    • Sym Tran Script of Cameras, Lights
    • Detail Corrections
reference

future work
Future Work
  • More NPR effects
  • More special effects(SFX) in production of animation.
  • Partial Collision Detection.
  • Model Picking in 2D.
