3D Animation PORTABLE
3D animation is the process of creating moving images in a three-dimensional (3D) environment, giving the illusion that these digital objects are moving through a 3D space. This is done by using computer software to create and manipulate digital objects, or by using specialized hardware such as motion capture (mo-cap) devices.
This is because objects in a three-dimensional space can be more accurately represented than those in two dimensions. As a result, 3D animation is often used for scenes that involve complex movements or actions, such as flying or explosions.
3D animation provides a greater sense of depth and scale, making it ideal for showing large landscapes, crowds, or altered realities. The use of three-dimensional models also makes it possible to create images that would be impossible or extremely difficult to generate with traditional animation techniques. This has made 3D animation tools like Cinemachine essential for filmmakers and video game developers who want to create high-quality and visually compelling scenes.
To create real-time animation, an animator first creates a 3D model of the object or character they want to animate. Next, they add rigging, which is a system of joints and bones that gives the model a skeleton. The animator then applies movement data to the rigged model, which brings the character to life. Finally, the animator adds textures and lighting to create a realistic look.
Real-time animation can also be used for simulations and other types of interactive applications. While real-time animation used to be limited to simple graphics, it has now evolved to create highly realistic images.
For years, film animation was primarily produced in two dimensions. However, the introduction of computer-generated imagery (CGI) ushered in a new era of 3D animation. Today, a variety of techniques are used to produce both 2D and 3D films. So, what are the key differences between these two types of animation?
3D film animation is created by rendering three-dimensional products on a two-dimensional surface. The objects are then lit and photographed from various angles, and the resulting images are composed into a sequence. This sequence is then played back at a high frame rate, creating the illusion of movement.
3D animation can be more realistic, but it can also be more expensive and time-consuming to produce due to the reliance on software. 2D animation is often cheaper and quicker to produce than 3D animation. 2D animation can also be more flexible when it comes to changes or corrections. On the other hand, 3D animation provides a more realistic look and feel, and is better suited for films with action-packed scenes or complex locations. Both types of animation have their own strengths and weaknesses, so the decision about which type of animation to use depends on the specific needs of the project.

3D animation is the process of creating three-dimensional models frame by frame . This is done by creating a model or character, rigging it with bones and joints, and then animating it to create the desired movement.
The key difference between CGI and 3D animation is that CGI uses three-dimensional objects to create the illusion of movement while 3D animation involves the construction of three-dimensional models frame by frame. 3D animation and CGI both have their pros and cons, so it really depends on what you're looking for in a visual effects solution. If you want to create static images, then CGI is a good choice. If you want to create the illusion of movement, then 3D animation is a better choice.
3D animation does not require drawing or coding, but it does require a significant amount of skill and training. 3D animators use computer software to create the illusion of movement. This involves creating three-dimensional models of objects and characters and then manipulating them to create the desired effect. To do this, animators must have a strong understanding of the principles of movement and how to use the software to create realistic animations.
3D animation is used in a variety of industries, including film, television, video games, and advertising. Its versatility makes it a popular choice for animators and directors across different mediums. While its use in feature films and television has been well-documented, 3D animation is also increasingly being used in video games and advertising. Its popularity in these industries is due to its ability to create realistic images and environments that are not possible with traditional 2D animation.
Computer animation is the process used for digitally generating animations. The more general term computer-generated imagery (CGI) encompasses both static scenes (still images) and dynamic images (moving images), while computer animation only refers to moving images. Modern computer animation usually uses 3D computer graphics to generate a three-dimensional picture. The target of the animation is sometimes the computer itself, while other times it is film.
Computer animation is essentially a digital successor to stop motion techniques, but using 3D models, and traditional animation techniques using frame-by-frame animation of 2D illustrations. Computer-generated animations can also allow a single graphic artist to produce such content without the use of actors, expensive set pieces, or props. To create the illusion of movement, an image is displayed on the computer monitor and repeatedly replaced by a new image that is similar to it but advanced slightly in time (usually at a rate of 24, 25, or 30 frames/second). This technique is identical to how the illusion of movement is achieved with television and motion pictures.
For 3D animations, objects (models) are built on the computer monitor (modeled) and 3D figures are rigged with a virtual skeleton. Then the limbs, eyes, mouth, clothes, etc. of the figure are moved by the animator on key frames. The differences in appearance between key frames are automatically calculated by the computer in a process known as tweening or morphing. Finally, the animation is rendered.
For 3D animations, all frames must be rendered after the modeling is complete. For pre-recorded presentations, the rendered frames are transferred to a different format or medium, like digital video. The frames may also be rendered in real-time as they are presented to the end-user audience. Low bandwidth animations transmitted via the internet (e.g. Adobe Flash, X3D) often use the software on the end user's computer to render in real-time as an alternative to streaming or pre-loaded high bandwidth animations.
To trick the eye and the brain into thinking they are seeing a smoothly moving object, the pictures should be drawn at around 12 frames per second or faster. (A frame is one complete image.) With rates above 75 to 120 frames per second, no improvement in realism or smoothness is perceivable due to the way the eye and the brain both process images. At rates below 12 frames per second, most people can detect jerkiness associated with the drawing of new images that detracts from the illusion of realistic movement. Conventional hand-drawn cartoon animation often uses 15 frames per second in order to save on the number of drawings needed, but this is usually accepted because of the stylized nature of cartoons. To produce more realistic imagery, computer animation demands higher frame rates.
Early digital computer animation was developed at Bell Telephone Laboratories in the 1960s by Edward E. Zajac, Frank W. Sinden, Kenneth C. Knowlton, and A. Michael Noll. Other digital animation was also practiced at the Lawrence Livermore National Laboratory.
In 1967, a computer animation named "Hummingbird" was created by Charles Csuri and James Shaffer. In 1968, a computer animation called "Kitty" was created with BESM-4 by Nikolai Konstantinov, depicting a cat moving around. In 1971, a computer animation called "Metadata" was created, showing various shapes.
An early step in the history of computer animation was the sequel to the 1973 film Westworld, a science-fiction film about a society in which robots live and work among humans. The sequel, Futureworld (1976), used the 3D wire-frame imagery, which featured a computer-animated hand and face both created by University of Utah graduates Edwin Catmull and Fred Parke. This imagery originally appeared in their student film A Computer Animated Hand, which they completed in 1972.
