For computer generated volumetric elements such as clouds, fire, and whitewater.

How are they made? Is it just a simple collection of particles [put to pixels] taken from Physics equations or are the like textures?

How are they applied? I would assume not from UV mapping

Derbis, smoke and fire come from the vehicle.

  • \$\begingroup\$ @XGundam05 that is my answer - tells me absolutely everything how to render fluid phenomena and how to seamlessly integrate fluid rendering into an existing rasterization-based framework, as told. Including the physics. The only problem is that I dont understand Partial Differential Equations so I dont think Il ever get a chance to work on stuff like this :/ \$\endgroup\$

Particle emitters with additive/multiplicative blending?

Maybe you mean something different? But I think the effects in that screenshot is made out of particles with additive blending, and then overlayed with particles with multiplicative blending (the darker parts).
