Motion blur in computer graphics refers to the visual effect that occurs when an object or scene is in motion and appears blurred or smeared. It is a technique used to simulate the perception of motion in a still image or a sequence of images.
In computer graphics, motion blur is achieved by calculating the average position of an object or scene over a given time interval and then blending the pixels together to create a blurred effect. This is done by taking into account the speed and direction of the moving object or camera, and the duration of the exposure.
The purpose of motion blur is to enhance the realism and convey a sense of movement in computer-generated images or animations. It helps to mimic the way our eyes perceive motion in the real world, where fast-moving objects appear blurred due to the persistence of vision.
Motion blur can be applied to various elements in computer graphics, including moving objects, camera movements, or even the entire scene. It is commonly used in video games, movies, and animations to create a more immersive and dynamic visual experience.
There are different techniques to achieve motion blur in computer graphics, such as vector-based motion blur, image-based motion blur, or post-processing effects. Each technique has its own advantages and limitations, and the choice depends on the specific requirements of the project.
Overall, motion blur is an essential concept in computer graphics that adds realism and dynamism to moving objects or scenes, making them visually more appealing and engaging.
