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 ]
Temporal anti-aliasing (TAA), also known as TXAA (a proprietary technology) [1] or TMAA/TSSAA (Temporal Super-Sampling Anti-Aliasing) [2], is a spatial anti-aliasing technique for computer-generated video that combines information from past frames and the current frame to remove jaggies in the current frame.
In supersample anti-aliasing, multiple locations are sampled within every pixel, and each of those samples [3] is fully rendered and combined with the others to produce the pixel that is ultimately displayed. This is computationally expensive, because the entire rendering process must be repeated for each sample location.
The encoding scheme may be flipped with the highest number being the value closest to camera. Depth buffers are an aid to rendering a scene to ensure that the correct polygons properly occlude other polygons. Z-buffering was first described in 1974 by Wolfgang Straßer in his PhD thesis on fast algorithms for rendering occluded objects. [1]
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 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 ...
The files store vector graphics data, embed or reference external bitmap images, and also a revision history of the project. Synfig can render to video formats such as AVI, Theora and MPEG, as well as animated graphics formats such as MNG and GIF. It can also render to a sequence of numbered image files, using formats such as PNG, BMP, PPM and ...
The lower left image shows a scene with a viewpoint marked with a black dot. The upper image shows the net of the cube mapping as seen from that viewpoint, and the lower right image shows the cube superimposed on the original scene. In computer graphics, cube mapping is a method of environment mapping that uses the six faces of a cube as the ...
