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.
This page provides a list of 3D rendering software, the dedicated engines used for rendering computer-generated imagery. This is not the same as 3D modeling software , which involves the creation of 3D models, for which the software listed below can produce realistically rendered visualisations.
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)
Versions of the teapot model — or sample scenes containing it — are distributed with or freely available for nearly every current rendering and modelling program and even many graphic APIs, including AutoCAD, Houdini, Lightwave 3D, MODO, POV-Ray, 3ds Max, and the OpenGL and Direct3D helper libraries.
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 ...
Re-rendering a game's graphics is not always possible, however; as was the case in 2012, when Beamdog remade BioWare's Baldur's Gate (1998). Beamdog were lacking the original developers' creative art assets (the original data was lost in a flood [5]) and opted for simple 2D graphics scaling with "smoothing", without re-rendering the game's ...
The basic object used in mesh modeling is a vertex, a point in three-dimensional space.Two vertices connected by a straight line become an edge.Three vertices, connected to each other by three edges, define a triangle, which is the simplest polygon in Euclidean space.
In visual effects, match moving is a technique that allows the insertion of 2D elements, other live action elements or CG computer graphics into live-action footage with correct position, scale, orientation, and motion relative to the photographed objects in the shot.
