Dynamics

Simulation Techniques

Dynamics are an extremely powerful feature in any 3D application. Without them there would be no particle effects like smoke, fire, realistic fluid effects, or computer, or complex cloth simulation.

  • Utilising dynamics is a vital step in your 3D generalist skill set.
  • Dynamics are calculated from a complex physics engine inside your 3D application, dynamics describes how objects move using rules of physics to simulate real forces.

A Brief History

Examples of Dynamics

  • Fantasia (Experimental hand drawn and painted dynamic effects)

‘Abstract music and abstract symbols on the page’

‘The relationship between music and visuals.’

  • The Abyss (James Cameron) – First fluid effect used in a feature film.
  • The Prince of Egypt (2D and 3D visual effects).
  • MPC – Modern VFX studio (Simulation Effects).

Maya Dynamics

When simulating anything in Maya, make sure to set your playback speed to ‘play every frame’. This forces each frame to be calculated without skipping a frame to match playback speed.
