Topic: Animation of the natural phenomena

Fire, water, fog, clouds, sand etc. Would be desirable to find something to esteem on __ animations of these processes. Unfortunately, search conducts on a photoshop and creation __ animations (and that not everything that it would be desirable. Normally to "fire" it is restricted). Questions to : whether program animation in games is used? Or only frame, drawn by artists in advance? Whether there are resources in a network (and what) whence it is necessary to begin  this question? There is something like an idea - press the mouse and in this place the lightning beats. How such to implement? If it would be desirable, that the lightning went from the different sides - the mouse at the left, a lightning on the right, the mouse at the left on top, a lightning on the right from below and .. In advance drawn all positions simply cannot be. I.e., most likely, program rendering is necessary? Or there are artful technicians?

Hello, VVV, you wrote: VVV> Questions to : whether program animation in games is used? Or only frame, drawn by artists in advance? Not absolutely about games, but I did program so (there still there is a water and the polar lights) Prerendereno there 10-15 frames for one  in a black-and-white variant. Then on it the gradient is superimposed on top, any more I do not remember, either on color or on a transparency.    on X and  upwards on Y, mixing up among themselves either on a transparency or through the filter (screen from a photoshop). Bonus of such implementation that it is possible to use different gradients, it is possible to use different sprites, it is possible to hinder different filters, it is possible to use different algorithms of movement, at me, for example, there it is noticeable that sometimes  glork in a heap, in a reality it happens over especially flashpoints where hot air rises upwards, causing air flows from the sides which incline to cent side , forming such fiery hill. Whether VVV> there are resources in a network (and what) whence it is necessary to begin  this question? I simply sat considered fire in slowmo, thought, how it can be implemented in digit. Tried different variants. It was necessary to write, likely, an article on this subject VVV> There is something like an idea - press the mouse and in this place the lightning beats.

The algorithm of creation of a realistic lightning somewhere is, I such came across something. There something similar to fractals. At first you draw a straight line. Then you halve, the middle  you take aside. Then each segment you halve, the middle you lead out  aside. Some times you repeat, similarity of a lightning turns out.

Hello, CEMb, you wrote: Thanks!! Very much for a long time, still in DOS did fire (I think, all did such) - a zero line -  (hottest), remaining lines are calculated on previous a minus small attenuation up, well and shift to the left/to the right. Good enough fire Turns out. There was a hope that already is ___ for such simulations. Type as is std:: sort which closes a question on sorting (not for  these words - std:: sort it is indeed good for __ cases). But search showed that while such magic potion, alas, no. There are quite good implementations, but they are reached by scrupulous __ parameters in one specific case.
