There are various softwares available in the market, that can render the complex computer generated images with smoke, fog and other similar media, but all these require a lot of memory, CPU usage and time. Now, a new technique is developed by the computer professionals of UC SAN DIEGO that can do the same but at a high speed with less memory and CPU requirements.

This technique can save the huge CPU time and it allows you to render the smoke, explosions etc at a much higher speed.

To render the images that are behind the smoke, fog etc. various factors are considered by the computer softwares. One important factor is to figure out the lighting in the cloudy or foggy atmosphere. In most of the softwares, the lighting is calculated at every point on the line of smoke between the eye and the image object. This calculation of lighting at every point requires a lot of time and computations and is a bottleneck. In the new technique, some shortcut methods are used to calculate the lighting that requires very less time, memory and CPU usage. This technique works great to create the realistic images in the presence of some hanging material in the air between the source of sight and the target image.
