Animation production technology

Key frames refer to every frame in which an object changes on the stage. It is used to define changes in animation, including the motion and characteristics of objects (such as size and color), adding or deleting objects in the scene, and adding frame actions. Keyframes must be used when the animation changes or requires action.

(2) Frame by frame animation.

Frame-by-frame animation, also known as keyframe animation, realizes the effect of motion by displaying animation image sequences frame by frame. Frame-by-frame animation is derived from traditional animation. Comics belong to frame-by-frame animation.

(3) Real-time animation.

Real-time animation, also known as algorithmic animation, uses various algorithms to realize the movement of objects. Algorithms include kinematics algorithm, dynamics algorithm and random motion algorithm. Real-time animation usually does not need to be recorded in memory. During operation, the computer quickly processes the input data and displays the results at any time in a time imperceptible to human eyes. Animation in electronic game machines is generally real-time animation.

(4) the movement of the object.

On the screen of real-time animation, a local image or object moves step by step along a fixed trajectory on a two-dimensional plane. The size, shape and color of the moving object and the object itself remain unchanged. In this way, the foreground can move on the background. The foreground can be an object or a paragraph of text or several words.

Its advantage is that it does not need to generate animation files.

(5) Motion control.

Motion control, also known as simulated motion, means that the computer first determines the position and relationship of each object, establishes its motion trajectory and speed, selects the motion forms such as translation, rotation and distortion, and then determines the abnormal mode and changing speed of the object shape.

(6) Animation data and animation files.

It is composed of frames of still images arranged in order, and the effect of scene movement is produced by playing the still images continuously. It is characterized by a large amount of data and only local content differences between frames. Animation data is compressed and recorded in a file with a certain format, which is an animation file.

(7) Flow control technology.

Flow control technology refers to the technology of playing while downloading. Its data is stored in a series of consecutive frames. As long as all the data of one frame is received, it can be played before the data of the subsequent frame arrives. Whether it can be played smoothly depends on two factors: first, the data of each frame must be as small as possible; Second, the download time of a series of frames must be less than their playing time.
