Evolution of Video Animation: From basic Handmade sketch to 3D video
The cartoon characters came in the early twentieth century that is derived from a sequence of handmade paintings. In manual animation include the illustration which is made with pencil and paper and each pose of the character is drawn separately for the creation in a logical sequence that gives the impression of movement. Nowadays, with the advancement of computing, there are few manual animations made for commercialization in movie. Initially, computer graphics enabled the productive process of animation to be increased, improve performance of business. However, it is not necessary to work around and paint every painting repeatedly, which reduces rendering time. This is due to the reason that traditional practices are transformed into digital practices in which the characters and animations have been done by the use of digital technology. This result in the development of video animation companies at different places that make it easier to develop and alter the content as per the requirements or targeted audience of the video content.
The computational aid in the animation process results in a digital cartoon that is mostly seen dimension 2D. The quality of these video content significantly depends on the number of pictures that segments the audiovisual work incomplete or limited animation. It is found that full 2D digital animation requires recording of at least 18 frames per second, which provide a detailed drawing and regular motion. Limited animation uses a smaller number of frames per second, which results in a less detailed drawing. The use of a smaller number of frames that connect the drawings to create the images reduces production costs but sacrifices the realistic description of the movements and images.
Consequently, full 2D digital animation tends to be used when looking for quality, as in the case of feature films, direct-to-video. However, 2D video animation becomes limited due to the introduction of 3D Video animator that present the more appealing video. Additionally, other animation technique can be performed with computational help, such as characters or any other object recorded in the frame.
There is no volume and the representation of reality depends on the perception of the animator, making the details of viewing and making it impossible to recognize the real object structure. With 3D images, which are composed together, it is possible to understand three-dimensional objects fully. In various audiovisual content its objects, characters and movements are based on computational specifications that are created in a virtual space. The production of a computer graphics image involves three basic steps. In the first, the graphic designer makes a computational geometric model that involves describing all the elements (such as objects and characters) of a scene. This is allocating characters appropriately in the virtual space and defining the variables that control the movements of elements. The second step involves defining the appearance of each element including color, texture, transparency and appearance. The third and final step is rendering the scene, which calculating the appearance of all pixels that convert the computational programming into images.
Video animation has contained some advantages. One of them derives from the fact that the image is the result of a computer program, which creates a collection of computations and variables of different images to be used when necessary in the animations. In addition, because the scenes can be treated at any time, the computer allows the graphic designer to make choices more efficiently. The consequences of this include the possibility of separating tasks from a process that is no longer needs to be applied for increasing the speed of production. For example, different animators can work at the same time with the face of a specific character while others work with their body or other relevant elements. However, there is a possibility that procedural non-linearity in computations of content results in infinite modifications of images. In relation to this, the interesting aspect of digital animation includes the contents that are produced are generally seen in the 3D dimension. This form of content can also be enlarged with the binocular vision technique, which consists of capturing the same image at two different horizontally aligned angles. This enables the graphic designer to increase animated video depth and give more realism to audiovisual content. Binocular vision is mainly used to produce blockbuster feature films.
