In 1997, 4D v6 was the first version of 4D to contain a fully integrated web server, allowing developers to translate 4D forms into HTML on the fly using only the 4D language. [ 12 ] In 2004, 4D 2004 was the first version of 4D to allow developers to create standalone, client/server, web and Service Oriented Applications (SOA) without changing ...

Imagix 4D is a source code analysis tool from Imagix Corporation, used primarily for understanding, documenting, and evolving existing C, C++ and Java software. [ 1 ] Applied technologies include full semantic source analysis.
4D BIM, an acronym for 4-dimensional building information modeling, refers to the intelligent linking of individual 3D CAD components or assemblies with time- or scheduling-related information. [ 35 ] [ 137 ] The term 4D refers to the fourth dimension : time , i.e. 3D plus time.
Pix4D is a Swiss software company that specializes in terrestrial and drone photogrammetry mapping software. It was founded in 2011 as a spinoff from the École Polytechnique Fédérale de Lausanne (EPFL) Computer Vision Lab in Switzerland. [1]
The homotopy type of a simply connected compact 4-manifold only depends on the intersection form on the middle dimensional homology. A famous theorem of Michael Freedman () implies that the homeomorphism type of the manifold only depends on this intersection form, and on a / invariant called the Kirby–Siebenmann invariant, and moreover that every combination of unimodular form and Kirby ...
Four-dimensional space (4D) is the mathematical extension of the concept of three-dimensional space (3D). Three-dimensional space is the simplest possible abstraction of the observation that one needs only three numbers, called dimensions , to describe the sizes or locations of objects in the everyday world.
The vessel's clearance is the distance in excess of the air draft which allows a vessel to pass safely under a bridge or obstacle such as power lines, etc.A bridge's "clearance below" is most often noted on charts as measured from the surface of the water to the underside of the bridge at the chart datum Mean High Water (MHW), [3] [4] a less restrictive clearance than Mean Higher High Water ...
