What is a digital movie?

Digital cinema, also known as digital cinema visual stunt, mainly refers to the technology of making movies by using computer graphics technology to process the images taken by film. It can not only process real images in reality, but also create images that don't exist in real life. Digital movies greatly enrich the means for artists to realize their artistic ideas, so that cameras are no longer the only means to make movies. It can create things that only exist in people's imagination, even things that people have never even thought about, and truly achieve the realm of "from life, higher than life".

To make a digital movie, we first need to "model", that is, to establish a mathematical model of the geometric characteristics of the object to be described on the computer. In digital movies, 3d scanner is often used as a modeling tool to scan the physical model in strict proportion to the real size and input it into the computer. After the physical characteristics of an object are recorded by a computer, these characteristic data can be used to simulate the appearance, movement and mode of the object. Then the simulated image is fused with the on-site shot image. Played out will produce vivid visual effects. Some stunt scenes are shot with digital film technology, which will have unprecedented shocking power.

The charm of digital movies can also be seen from the box office income. According to statistics, during the period of 1996, the domestic box office receipts of American movies exceeded 1 100 million dollars: Independence Day (4130 thousand dollars), Mission Impossible (268 million dollars) and Tornado (249 million dollars). The first digital movie, Jurassic Park, grossed $868 million. The great success of these films is not unrelated to the wide use of digital film technology.
