  2. Computer representation of surfaces - Wikipedia

    en.wikipedia.org/wiki/Computer_representation_of...

    An open surface with u- and v-flow lines and Z-contours shown. In technical applications of 3D computer graphics such as computer-aided design and computer-aided manufacturing, surfaces are one way of representing objects. The other ways are wireframe (lines and curves) and solids.

  3. Waveform graphics - Wikipedia

    en.wikipedia.org/wiki/Waveform_graphics

    Waveform graphics were limited, but could still produce useful output when used in conjunction with programs like gnuplot. Waveform graphics is a simple vector graphics system introduced by Digital Equipment Corporation (DEC) on the VT55 and VT105 terminals in the mid-1970s. It was used to produce graphics output from mainframes and ...

  5. Painter's algorithm - Wikipedia

    en.wikipedia.org/wiki/Painter's_algorithm

    A fractal landscape being rendered using the painter's algorithm on an Amiga. The painter's algorithm (also depth-sort algorithm and priority fill) is an algorithm for visible surface determination in 3D computer graphics that works on a polygon-by-polygon basis rather than a pixel-by-pixel, row by row, or area by area basis of other Hidden-Surface Removal algorithms.

  6. Computer graphics (computer science) - Wikipedia

    en.wikipedia.org/wiki/Computer_graphics...

    A modern rendering of the Utah teapot, an iconic model in 3D computer graphics created by Martin Newell in 1975. Computer graphics is a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content. Although the term often refers to the study of three-dimensional computer graphics, it also ...

  7. Physically based rendering - Wikipedia

    en.wikipedia.org/wiki/Physically_based_rendering

    The phrase "Physically Based Rendering" was more widely popularized by Matt Pharr, Greg Humphreys, and Pat Hanrahan in their book of the same name from 2004, a seminal work in modern computer graphics that won its authors a Technical Achievement Academy Award for special effects. [2] The book is now in its fourth edition. [3]

  8. Surface wave inversion - Wikipedia

    en.wikipedia.org/wiki/Surface_wave_inversion

    Surface-wave inversion is the method by which elastic properties, density, and thickness of layers in the subsurface are obtained through analysis of surface-wave dispersion. [2] The entire inversion process requires the gathering of seismic data, the creation of dispersion curves, and finally the inference of subsurface properties.

  9. Surfel - Wikipedia

    en.wikipedia.org/wiki/Surfel

    Surfel is an abbreviated term for a "surface element," analogous to a "voxel" (volume element) or a "pixel" (picture element).In 3D computer graphics, the use of surfels is an alternative to polygonal modeling.
