The volumetric clouds feature extends Tempest’s
environmental effects module which currently includes flat cloud
layers such as cirrus and stratus, an ephemeris model and weather
effects such as rain and snow. Now, an unlimited number of cloud
layers can be created, including a superficial cloud and transition
or “scud” layer to give depth and realism. These
features are particularly useful in flight simulation where challenging
cloud scenarios can be used in training.
Each volumetric cloud layer is generated procedurally
and is affected by wind and lighting. The volumetric cloud
layers blend seamlessly with existing scenery and lighting systems
and,
unlike many existing implementations, can extend over very
large distances. |
