The objects in 3-D computer graphics are often referred to as 3-D models. Unlike the rendered image, a model's data is contained within a graphical data file. A 3-D model is a mathematical representation of any three-dimensional object; a model is not technically a graphic until it is displayed.
Backgrounds in fixed 3D games tend to be pre-rendered two-dimensional images, but are sometimes rendered in real time (e.g. Blade Runner). The developers of SimCity 4 took advantage of fixed perspective by not texturing the reverse sides of objects (and thereby speeding up rendering) which players could not see anyway. [4]
Demonstration of the multiplane effect using three planes. The technicians at Fleischer Studios created a distantly related device, called the Stereoptical Camera or Setback, in 1934. [3] Their apparatus used three-dimensional miniature sets built to the scale of the animation artwork. [3]
However, in applications which involve CT scans a three-dimensional model is automatically produced from many single-slice x-rays, producing "computer generated image". Applications involving magnetic resonance imaging also bring together a number of "snapshots" (in this case via magnetic pulses) to produce a composite, internal image.
An autostereogram is a two-dimensional (2D) image that can create the optical illusion of a three-dimensional (3D) scene. Autostereograms use only one image to accomplish the effect while normal stereograms require two. The 3D scene in an autostereogram is often unrecognizable until it is viewed properly, unlike typical stereograms.
Three-dimensional (3D) art may refer to: . digital art created using 3D computer graphics; any form of visual art resulting in a three-dimensional physical object, such as sculpture, architecture, installation art and many decorative art forms
The 3D reconstruction of objects is a generally scientific problem and core technology of a wide variety of fields, such as Computer Aided Geometric Design , computer graphics, computer animation, computer vision, medical imaging, computational science, virtual reality, digital media, etc. [3] For instance, the lesion information of the ...
3D computer graphics, computer graphics that use a three-dimensional representation of geometric data; 3D display, a type of information display that conveys depth to the viewer; 3D film, a motion picture that gives the illusion of three-dimensional perception; 3D modeling, developing a representation of any three-dimensional surface or object
