In some implementations the checkerboard grid will be alternated between frames, with the previous frame's image data being held in memory, and then used to aid with reconstructing the scene. [ 2 ] A similar technique was used in the 1993 video game Doom , which had a "low detail" mode that only rendered every other column of pixels to improve ...
If a computer has two video cards that combine their outputs into a single video monitor, then one of four methods could be used to create the images. Alternate Frame Rendering (AFR): One graphics processing unit (GPU) computes all the odd video frames, the other renders the even frames. (i.e. time division)
The frames rendered from different points of view can improve image quality with anti-aliasing or add effects like depth-of-field and three-dimensional display output. This approach allows for good performance scaling but no data scaling. When rendering sequential frames in parallel there will be a lag for interactive sessions.
Several different, and often specialized, rendering methods have been developed. These range from the distinctly non-realistic wireframe rendering through polygon-based rendering, to more advanced techniques such as: scanline rendering, ray tracing, or radiosity. Rendering may take from fractions of a second to days for a single image/frame.
A render farm is different from a render wall, which is a networked, tiled display used for real-time rendering. [1] The rendering of images is a highly parallelizable activity, as frames and sometimes tiles can be calculated independently of the others, with the main communication between processors being the upload of the initial source ...
Reyes rendering is a computer software architecture used in 3D computer graphics to render photo-realistic images. It was developed in the mid-1980s by Loren Carpenter and Robert L. Cook at Lucasfilm 's Computer Graphics Research Group, which is now Pixar . [ 1 ]
A distinction is made between real-time rendering, in which images are generated and displayed immediately (ideally fast enough to give the impression of motion or animation), and offline rendering (sometimes called pre-rendering) in which images, or film or video frames, are generated for later viewing. Offline rendering can use a slower and ...
In the field of 3D computer graphics, Multiple Render Targets, or MRT, is a feature of modern graphics processing units (GPUs) that allows the programmable rendering pipeline to render images to multiple render target textures at once. These textures can then be used as inputs to other shaders or as texture maps applied to 3D models.
