A NURBS curve. (See also: the animated creation of a NURBS spline.) A NURBS surface. Non-uniform rational basis spline (NURBS) is a mathematical model using basis splines (B-splines) that is commonly used in computer graphics for representing curves and surfaces.
TSNLib – analyze NURBS based trimmed surface representations. GSNLib – based on NLib with curve/curve and surface/surface intersection abilities. NLib – an advanced geometric modeling kernel based on NURBS curves and surfaces. VSLib – deformable modeling using the constrained optimization techniques of the calculus of variations.
Freeform surface modelling is a technique for engineering freeform surfaces with a CAD or CAID system.. The technology has encompassed two main fields. Either creating aesthetic surfaces (class A surfaces) that also perform a function; for example, car bodies and consumer product outer forms, or technical surfaces for components such as gas turbine blades and other fluid dynamic engineering ...

Ways to polish a surface (using a little bit of force). 3. These words are related to "betting." 4. The words in this category precede a seven-letter plural noun (hint: the noun usually refers to ...
The full moon is totally within Earth's shadow and glows with a dim orange color during a total lunar eclipse photographed early on the morning of Jan. 21, 2019.
Catmull–Clark level-3 subdivision of a cube with the limit subdivision surface shown below. (Note that although it looks like the bi-cubic interpolation approaches a sphere, an actual sphere is quadric.) Visual difference between sphere (green) and Catmull-Clark subdivision surface (magenta) from a cube
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
