Atmosphere Examples
Back to the Atmosphere Dialog.
Please note that half-heights are now measured in metres,
not terrain units. This affects some of the advice given on this
page.
All these examples are taken from the same location
on the same landscape. The only things that change in each scene
are the atmospheric settings. This picture shows the scene with
the default settings.
In this picture, I used Simple Haze Density of 80%
while leaving all other settings intact. This gives a
good impression of a dark, foggy day. |
 |
Here I used a Simple Haze Density of 72%, and I also
lowered the Simple Haze Half-height to 5.7, giving a nice
effect of low mist. When viewed from above, using this
sort of combination can be used to effectively show low
mist from above, although the sky can look "too blue" without the haze
acting properly on it. |
 |
Be careful of increasing the Atmospheric Blue density
too much without compensating with other elements. here,
it is set to 40% and even here the sky looks far too
light and the whole image has a slightly
"ghostly" feel to it. |
 |
Here I raised the Light Decay (Reddening) to 50%.
This is more exaggerated than would normally be desired,
but raising this value slightly can give a little more
"warmth" to scenes, especially sunsets. It is
too easy to go too far, though. |
 |
This is an effect I use quite frequently - I reduced
all half-heights to 32. This can give an effect of higher
altitude by "thinning" the atmosphere as would
happen at high altitude. The rendering of the landscape
is not affected very much, but the blue colour of the sky
gets much deeper. |
 |
The key to maintaining realism in Terragen images is to not go
for extreme values of atmospheric settings (or, for that matter,
any settings). However, nature does sometimes produce results
which are extreme, so perhaps this advice shouldn't be taken too
literally... As always, the best way to get the results that you
want is to experiment!
