Fog Polygon Volumes
by nVidia
Entry created by Andreas Jung. | Calculates fog depth at each pixel from actual 3D fog geometry. Requires extra passes, but should scale well with other render-to-texture techniques. Should be even more doable with todays floating-point-render-targets. [IMO] Although not seen in flight simulation, there is no reason why this technique shouldn't be employed within a flight simulator. It could also be used to render clouds - and the cloud-geometry could also be used to render the shadows of the clouds. Negative fog volumes could be used to simulate shafts of light. |
