Challenges

  • Procedurally modeling of frills on jellyfish
  • Procedurally animating propulsion of jellyfish
  • Creating a swarm
  • Creating an underwater environment

9 of 25

Procedurally Modeling of Frills on Jellyfish

  • Multiplication of UV component
  • Modulus function of resultant value

10 of 25

Procedurally Modeling of Frills on Jellyfish

  • Sine function used
  • Values fitted appropriately
  • Masked by UV component

11 of 25

Procedurally Animating Propulsion of Jellyfish

  • Animating sine wave
  • Rotation of points about a point in VOPs
  • Transforms masked by UV component

Creating a Swarm

  1. Scattering 3 points in a sphere
    • Stamped random seed
  2. NURBS curve generated procedurally
  3. Curves copied onto more scattered points

​

  • Jellyfish animated on curves procedurally
    • Randomised speed and position
