A variety of computer graphic techniques have been used to display video game content throughout the history of video games.The predominance of individual techniques have evolved over time, primarily due to hardware advances and restrictions such as the processing power of central or graphics processing units.
Note the blue fringe that is particularly noticeable along the right edge of the window. Bloom (sometimes referred to as light bloom or glow) is a computer graphics effect used in video games, demos, and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world cameras. The effect produces fringes (or feathers) of light ...
In first person video games, the field of view or field of vision (abbreviated FOV) is the extent of the observable game world that is seen on the display at any given moment. It is typically measured as an angle, although whether this angle is the horizontal, vertical, or diagonal component of the field of view varies from game to game.
The idea behind ray casting, the predecessor to recursive ray tracing, is to trace rays from the eye, one per pixel, and find the closest object blocking the path of that ray. Think of an image as a screen-door, with each square in the screen being a pixel. This is then the object the eye sees through that pixel.
Screen tearing[ 1] is a visual artifact in video display where a display device shows information from multiple frames in a single screen draw. [ 2] The artifact occurs when the video feed to the device is not synchronized with the display's refresh rate. That can be caused by non-matching refresh rates, and the tear line then moves as the ...
Virtual retinal display. A diagram showing the workings of the virtual retinal display. A virtual retinal display ( VRD ), also known as a retinal scan display ( RSD) or retinal projector ( RP ), is a display technology that draws a raster display (like a television) directly onto the retina of the eye.
Ray-cast image of idealized universal joint with shadow. Ray casting is the methodological basis for 3D CAD/CAM solid modeling and image rendering. It is essentially the same as ray tracing for computer graphics where virtual light rays are "cast" or "traced" on their path from the focal point of a camera through each pixel in the camera sensor to determine what is visible along the ray in the ...
v. t. e. Volumetric lighting, also known as " God rays ", is a technique used in 3D computer graphics to add lighting effects to a rendered scene. It allows the viewer to see beams of light shining across the environment. Examples of volumetric lighting are seeing sunbeams shining through a window and seeing sunbeams radiating when the Sun is ...
