3D Computer Graphics make the film industry more glorious

Nowadays, Computer Graphics (CG) and Animations has become an inevitable element in movies. Almost all the film makers are utilizing the Computer Graphics in their films for different reasons, in different ways.
Many people thought that titanic ship was filmed in sea, which is simply possible. But the fact is that the Titanic was filmed in 5,000,000 (US) gallon tank and the ship finally submerged into the tank and not into the sea. However, in the movie, it was made to look as if it was submerged into the sea and it looked perfectly real.
That was possible due to 3d Computer Graphics technology which can help to create realistic visuals that are simply impossible to shoot. With 3d computer graphics it is possible for film makers to show impossible things as possible in their movies. Another classic example is the film "The Chronicles of Narnia" where the Lion Aslan speaks and interacts with human beings. It was simply impossible for us to make the act a real lion so natural and realistic. However, with 3d Graphics it was possible for film makers to have a real lion in the movie.
Computer Graphics helped to many comical characters to get life and real. In those days, enjoyed the stunts of superman, spider-man from the comic books, but today, you can enjoy their stunts more lively from their movies. Many people were just surprised and got goose bumps when they saw spider-man swinging amidst the building of New York City. And in fact many people though that actor was really doing the stunts.
Today, Computer Graphics technology has become too advanced that it is possible for the film makers to have impossible scenes in their movies. In those days, film directors and camera man, took risks and pain to shot some magnificent scenes. But today, computer graphics helps the directors to show the magnificent and unbelievable scenes without much physical effort and without undertaking pain.
Those days, CG was rendered using usual stand-alone computers. Rendering CG was complex computing task that requires extremely powerful processor and big memory space. However, the processor and memory of stand-alone computers were are sufficient to render advanced CG smooth and quick. It took very long to render CG successfully.
But render farm which is built using interlinking of several computers has all the potential to render any kind of advanced CG smooth and quickly. This is one of the prime reasons why CG industry is able to produce more number of graphics in short time. Moreover, render farms after effects are simply amazing when compared to those rendered by ordinary computers.
Render farm is another important reason that made it possible for the CG artist to render CG fast. Rendering high level CG was very time consuming those days as the memory of processor of the stand-alone computer unable to process the rendering process quickly. But render farm, being a high-performance computer helped the CG artist to render CG very quick and fast. Like OS, the render farm needs render farm software to bridge between the user and hardware. Nowadays, many advanced render farm software has come, which helps the CG artist to make the best out of render.
