3DLDF
Encyclopedia
GNU 3DLDF is a GNU
software package for three-dimensional
technical drawing. Currently, its only form of output is MetaPost
code. GNU 3DLDF is written in C++
using the CWEB
package created by Donald Knuth
and Silvio Levy. It is intended, among other things, to provide a convenient way of creating 3D graphics for inclusion in TeX
documents and to fit in with the "family" of programs associated with TeX
. It was written by Laurence D. Finston. 3DLDF stands for "3D" plus the initials of the author (LDF). This name was chosen because the author considered it unlikely that it would clash with the name of any other software package for 3D graphics.

Three-dimensional space
Three-dimensional space is a geometric 3-parameters model of the physical universe in which we live. These three dimensions are commonly called length, width, and depth , although any three directions can be chosen, provided that they do not lie in the same plane.In physics and mathematics, a...

MetaPost
MetaPost refers to both a programming language and the interpreter of the MetaPost programming language. Both are derived from Donald Knuth's Metafont language and interpreter. MetaPost excels at producing diagrams in the PostScript programming language from a geometric/algebraic description...

C++
C++ is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language. It is regarded as an intermediate-level language, as it comprises a combination of both high-level and low-level language features. It was developed by Bjarne Stroustrup starting in 1979 at Bell...
