Generalized Cylinders

• Book calls these Sweep Representations

  • Specify 2D cross-sectional shape
  • Specify 3D skeleton curve
  • “Sweep” cross-sectional shape along skeleton curve
    • shape normal should be parallel to curve tangent

• Simple example: cylinder

  • cross-section is circle
  • skeleton is line

• Can vary cross-sectional shape for more interesting sweeps

• You will be implementing these for Assignment 2
