What Goes Behind 3D Animation
Knowing what goes on behind 3D animation production is important for you as business manager as it will facilitate the process of collaboration.
What is 3D Animation – 3D animation refers to the work of creating moving pictures in a three-dimensional digital environment through the careful manipulation of objects. Picture sequences can then be exported giving the illusion of movement based on how the objects are humiliated.
- Modeling – the process of creating the 3D objects within a scene,
- layout and animation – determines how objects are positioned and animated within a scene
- rendering – final output of the completed computer graphics
Modeling – Modeling is the process of molding a shape into a completed 3D mesh. The modeler would typically take a simple object, called a primitive, and extend it into a shape that can be refined. Each of these primitives is then manipulated to create an object. The three basic methods you can use to create a 3D model are:
- Spline or patch modeling – The most traditional form of 3D animation modeling, it involves creating a cage of splines to form a ‘skeleton’ of the object. The software is used to make a 3D skin around the shape. The method is generally used for creating hard objects, like cars and buildings.
- Box modeling – Resembling traditional sculpting, box modeling starts with a primitive, usually a cube. The modeler begins adding detail by slicing the primitive into pieces and extending faces to create the desired form. The method is quite effective in creating the basic shape of the model.
- Poly modeling – A precise technique, poly modeling is used for creating a 3D mesh point-by-point, face-by-face. The modeler will generally start out with a single quad and extrude an edge of the quad, creating another quad attached to the first. The 3D model is gradually developed in this way.
Layout and Animation – Layouts you see on the screen are drawn from storyboards that define the action and perspective. Artists then take it to the next level by adding the details. Their job also involves dividing 2D storyboards into 3D shots, staging the shots and plotting the action that will take place within each scene. They also have to ensure that everything that is going to be animated is set up adequately.
Animators will then use professional level modeling tools to spring life into the models.
A static 3-D model can be viewed interactively or can be rendered in different ways and different lighting conditions. Applications can be created for sales presentations, scientific simulation, product design, architecture, environmental planning and more.
Rendering – The process involves automatically converting 3D wire frame models into 2D images with 3D photorealistic effects on a computer. The animation program would take the various components, variables, and actions to builds the final view able result. It can be an individual image or a series of frames sequenced into video format.
