Which best explains how 3D art appears in modern movies?
3D art in modern movies is created through a process called computer-generated imagery (CGI) or computer animation. It involves the use of complex software and computer algorithms to create three-dimensional objects, characters, and environments that look realistic or stylized.
First, artists create a 3D model using specialized software. They define the shape, texture, and appearance of the object or character by manipulating virtual polygons. These models can be based on real-life objects, scanned from physical objects, or entirely conceptual creations.
Next, artists apply textures to the 3D models, giving them surfaces that mimic realistic materials like metal, glass, or fabric. They may also add lighting effects to simulate natural or artificial lighting conditions. The shaders and materials applied to the models make them look more lifelike by determining how they reflect, refract, or absorb light.
To bring the 3D models to life, animators create a series of keyframes or a skeletal structure that defines the movement and behavior of characters or objects. They define the positions, rotations, and movements at specific points in time, and the computer interpolates the in-between frames to create smooth animation sequences.
Finally, the 3D models and animations are rendered, which is the process of generating the final images or frames of the movie. This involves calculating how the virtual cameras “capture” the 3D scenes from different angles and perspectives. The computer then simulates the interaction of light with the objects and materials, creating realistic shadows, reflections, and refractions.
The rendered frames are then composited with live-action footage or other visual effects to create the final seamless integration of the 3D elements into the movie. This integration is done through techniques like match moving, where the computer matches the movement of the live-action camera to the virtual camera.
Overall, 3D art in modern movies is a result of advanced computer graphics technology and the expertise of artists and animators who create and manipulate virtual objects and characters to enhance storytelling and provide visually stunning visual effects.
