gle - Graphics Layout Engine SYNOPSIS
gle [options] file.gle ... DESCRIPTION
GLE (Graphics Layout Engine) is a graphics scripting language designed for creating publication quality graphs, plots, diagrams, figures and slides. GLE supports various graph types (function plots, histograms, bar graphs, scatter plots, contour lines, color maps, surface plots, ...) through a simple but flexible set of graphing commands. More complex output can be created by relying on GLE's scripting lan- guage, which is full featured with subroutines, variables, and logic control. GLE relies on LaTeX for text output and supports mathematical formulea in graphs and figures. GLE's output formats include EPS, PS, PDF, JPEG, and PNG. DOCUMENTATION

gle - an introduction to the GLE Tubing & Extrusions Library SYNOPSIS
#include <GL/gle.h> DESCRIPTION
The GLE Tubing and Extrusion Library is a graphics application programming interface (API). The library consists of a number of "C" lan- guage subroutines for drawing tubing and extrusions. The library is distributed in source code form, in a package that includes documenta- tion, a VRML proposal, Makefiles, and full source code and header files. It uses the OpenGL (TM) programming API to perform the actual drawing of the tubing and extrusions. A "sweep" or "extrusion" is a 2D contour (polyline) that is swept or extruded along a 3D path (polyline). For example, sweeping a circle along a straight line will generate a cylinder. Sweeping a circle along a circular path will generate a doughnut (torus). The library also includes a set of utility routines for drawing some of the more common extruded shapes: a polycylinder, a polycone, a gen- eralized torus (circle swept along a helical path), a "helix" (arbitrary contour swept along a helical path) and a "lathe" (arbitrary con- tour swept along a helical path, with torsion used to keep the contour aligned). The most general extrusion supported by this library allows an arbitrary 2D contour to be swept around an arbitrary 3D path. A set of nor- mal vectors can be specified to go along with the contour; the normal vectors determine the appearance of the contour when lighting is turned on. A set of colors and affine matrices can be specified to go along with the 3D path. The colors are used to color along the path. The affine matrices are used to operate on the contour as it is swept along. If no affine matrices are specified, the contour is extruded using the mathematical concept of "parallel translation" or "Gaussian translation". That is, the contour is moved (and drawn) along the extrusion path in a "straight" manner. If there are affine matrices, they are applied to the contour at each extrusion segment before the segment is drawn. The affine matrices allow work in a quasi-non-Euclidean space. They essentially allow the contour to be distorted as it is swept along. The allow the contour to be rotated, translated and rescaled as it is drawn. For example, a rescaling will turn a polycylinder into a poly- cone, since the circle that is being extruded is scaled to a different size at each extrusion vertex. A rotation allows the contour to be spun around while it is being extruded, thus for instance allowing drill-bit type shapes to be drawn. A translation allows the appearance of shearing in real space; that is, taking a contour and displacing it, without otherwise bending it. Note that the affines are 2x3 matri- ces, not 3x4 matrices, since they apply to the 2D contour as it is being extruded. WEB SITE
