A very common scientific phenomenon…

All around you you can easily observe small peculiarities of nature that arise when certain conditions are met. While we generally do not pay much attention to them, sometimes some of them are a little more striking than others, especially when we first notice them when we grow up. Among them we find, for example, the Schlieren effectalso called Strioscopy. Behind this somewhat barbaric name lies in reality a very widespread phenomenon: that of power Observe air disturbances with the naked eye.

Normally, the air, whether hot or cold, is completely invisible. If you walk through the city in the middle of summer, you can sometimes see heat distortions right above the paved streets. You can also observe such an effect above radiators, exhaust pipes or other immediate heat sources. This famous Schlieren effect is actually related to a very simple concept in physics: the reflection of light when it passes through two bodies of different densities.

…which shows a lot of attention to detail!

When we create a video game, we often score points in terms of realism and immersion by thinking about adding these kinds of common scientific phenomena. Since they are completely banal, we tend to forget about them and integrate them into our daily lives without paying attention. But it is precisely when we notice their absence that the whole thing seems strange to us. For this reason, the developers of Call of Duty 4 Modern Warfare were particularly intelligent in thinking Add the streaking effect behind the exhaust pipes of your tanks:

In Call of Duty 4: Modern Warfare, you can see the air behind the tank deforming due to the heat. This optical effect is called the Schlieren effect and occurs when air expands, causing a change in the reflection index.

Even though the game dates back to 2007, players seem to be impressed by the attention to detail the developers put into it. Of course, this wasn’t the first time a game had aimed to replicate this scientific phenomenon, and nowadays it’s almost a given to do so. But back then, it wasn’t necessarily so easy to say so. Proof that Call of Duty and Activision really did strive to stand out from the competition by paying special attention to realism, even if the goal wasn’t to make a simulation game either.
