Computer-generated imagery, or CGI, uses computers to create visual effects and 3D graphics for use in films, television shows, and video games. Creating CGI involves several steps, including modeling, animating, lighting, and rendering.
To begin, artists and designers use specialized software to create 3D models of the objects, characters, and environments that will be included in the final CGI image or animation. This involves creating a virtual skeleton and defining the movement and behavior of each object.
Next, the animation team uses 3D models to create the movement and action included in the final image or animation. This involves defining each object's keyframes, or key positions, and letting the software calculate the intermediate frames to create the desired movement.
Once the models and animation are complete, the lighting team adds virtual lights to the scene to create the desired mood and atmosphere. This involves choosing the type and color of the lights and their intensity and placement.
Finally, the rendering team uses specialized software to create the final CGI image or animation. This involves calculating the color and brightness of each pixel in the image based on the 3D models, animation, and lighting and then combining all of the pixels into a single image or sequence of images.
Overall, creating CGI involves combining specialized software, artistic skill, and technical expertise to create highly realistic and immersive visual effects and graphics.
