APEX Turbulence

APEX Turbulence enables high definition smoke and fog interaction, dust devils, sand and snow storms  as well as supernatural effects in games to provide a much more dynamic and interactive game experience. It can be used to augment any existing particle techniques with realistic response to moving solid objects and turbulent fluid motion. The simulation quality can be easily scaled up  or down based on target platform performance.  The authoring tool allows the artist to change parameters such as fluid viscosity, turbulence and particle mass to create inspiring particle effects based on fluid dynamics.

Some application scenarios could include:

  • Residual dust from destruction
  • Smoke Grenades and other Weapon effects
  • Exhaust smoke from care or spinning/braking tires
  • Supernatural effects – e.g. ghost like
  • Snow storms or snow trails
  • Tornado wind effects

 

Game Examples:

Dark Void

APEX Turbulence was used in DarkVoid to enhance the weapon and jetpack effects. Up to 100k particles were used for the disintegrator and jetpack effects to create a cinematic game experience. The video below illustrates how the game experience was changed significantly.
