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.
Surface rendering of Arabidopsis thaliana pollen grains with confocal microscope. Scientific visualization (also spelled scientific visualisation) is an interdisciplinary branch of science concerned with the visualization of scientific phenomena. [2] It is also considered a subset of computer graphics, a branch of computer science. The purpose ...
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.
In computer graphics, tessellation is the dividing of datasets of polygons (sometimes called vertex sets) presenting objects in a scene into suitable structures for rendering. Especially for real-time rendering , data is tessellated into triangles , for example in OpenGL 4.0 and Direct3D 11 .
The boundaries are defined by lines, conics, polylines, surface curves, or b spline curves; ISO 10303-514 Advanced boundary representation, a solid defining a volume with possible voids that is composed by advanced faces; ISO 10303-509 Manifold surface, a non intersecting area in 3D that is composed by advanced faces
The word "hierarchical" in the name refers to a notable feature of PHIGS: unlike most graphics systems, PHIGS included a scene graph system as a part of the basic standard. Models were built up in a Centralized Structure Store (CSS), a database containing a "world" including both the drawing primitives and their attributes (color, line style ...
An IGES file is composed of 80-character ASCII records, a record length derived from the punched card era. Text strings are represented in "Hollerith" format, the number of characters in the string, followed by the letter "H", followed by the text string, e.g., "4HSLOT" (this is the text string format used in early versions of the Fortran language).
