Computer-Generated Imagery: One of the Best Things that Ever Happened to Film-Making

Computer-generated imagery (CGI) has done a lot of amazing wonders in enriching our movie viewing experience. We have seen lifelike dinosaurs in “Jurassic Park,” all incredibly looking realistic through use of physically-textured computer generated images.

CGI Made us Believe All Movie Scenes Were for Real

Incredible reenactments of historical moments in films like Pearl Harbor, were made possible as CGI advanced and reached new heights. Audience felt the gripping moments when the U.S. became a major participant in World War II, as they watched true-to-life depictions of Japanese air fighters launching a brutal attack on the U.S. naval base. CGI technicians created the visual effects by merging shots of the USS Arizona as model for the sequence, whilst creating body simulations and inserting smoke plumes.

Virtual worlds where scenes with which viewers have to believe that they were seeing actions shot entirely in the middle of the vast ocean made use of CGI. “Pirates of the Caribbean: Dead Men Tell No Tales” achieved the fighting scenes in a water environment by way of CGI. Creators had to first take shots of a stuntman in appropriate costume inside a swimming pool, delivering every conceivable action stuff that stuntmen do when engaged in skirmishes; including walking and stepping away, as well as while underwater.

The action shots served as manipulative elements of the virtual water environment, where CGI used different computer algorithms to follow the rules of real life topography, gravity, locomotion and communication to combine with real-time action.

On a different perspective, use of CGI made it possible for actors to virtually interact with real, ferocious beasts as in the movie “Life of Pi.” Pi, an Indian teenage boy is the only survivor of a shipwreck. However, he finds himself as a potential prey of a Bengal tiger who is also onboard a lifeboat adrift in the middle of the sea.

Here, the virtual water world was created using an above-ground-pool, which we presume had pool steps to allow ease in maneuvering Pi’s floating lifeboat. CGI made us believe that the Bengal tiger, with which Pi interacted and communicated throughout the water scene episode, was actually onboard the vessel.

Computer-generated imagery greatly improved cinematography by the 1990s, as scenes were no longer confined and constrained by the actual laws of physics. The evolution and continuing sophistication of CGI software have made many of us believe once more, in superheores. Yet we all know that modern superhero movies like Marvel’s series of Avengers movies would not be possible without computer-generated effects and computer-generated imagery.
