The light manager is responsible for positioning and defining the lighting properties, defines the interaction with different materials and calculates the intensity of the shadows to make a 3D scene credible. Finally, the lighting gives the scene the harmony of colours and the warmth that is necessary for the right presentation.
Rigging is the term used to define the movements of mechanical objects. The technicians who deal with this phase have the task of showing all the positions a character can take during the animation, setting limits and restrictions to make the movement credible and natural.
In this phase, the animators give the objects and characters the movement described in the storyboard. The technique for animating 3D objects does not differ much from that for 2D objects. Motion Capture is often used to make the animation of characters as credible as possible. This technique is used to visualize the movement of real actors.
After completion of the animation phase, the project goes into the rendering phase. This name specifies the mathematical calculation that computer processors must perform in order to export the frames in the required quality.
In the final phase of the production process, 3D animation is given the finishing touches with video audio editing and the use of special effects.
Some scenes require special effects such as rain, snow, explosions or smoke. These effects can be generated in post-production by special software using particle animation techniques that can realistically simulate the movement of small particles exposed to gravity and other physical forces such as wind, vertices, weight, friction, etc.
