How was Avatar filmed?

The movie Avatar was shot with a 3D camera independently developed by James Cameron.

The cast of Avatar uses the world's top high-definition stereo camera equipment, plus a virtual camera that can observe the fit between the actors' actions and the virtual world in real time when shooting live performances, so that Cameron can adjust and guide each scene of the actors on the spot-which can save a lot of time for later "correction".

In addition, Cameron also used innovative facial capture equipment. He installed such a camera device on the head of every actor who needs to "capture the performance". The core of the device is a miniature high-definition camera, which is only a few inches away from the actor's face. It can record the subtle expression changes of the actor's face with a wide-angle lens, and then transmit 95% of the action of the actor's face to the virtual character in the computer, so that the computer-generated character's every move is no different from that of the real actor.

The technology used in Avatar

1, the face CG was accurately captured for the first time, even the muscle micro-expression could be captured.

2. Virtual camera: The director takes a virtual camera to shoot actors directly on the stage, and the monitor will directly display the movie environment and characters simulated by CG.

3. Combination of 3D camera and 2D camera: This means that the photographer can take a camera and shoot 3D in a narrow space. Therefore, the shooting of 3D movies and the movement of mirrors are more free, and the movie picture is more realistic.

4. The combination of virtual camera and 3D camera is called cooperative camera: this technology can take 3D pictures of CG background modeled by people and computers.
