C++ code to generate SVG files
Various classes for objects which can be written to a SVG file. Most of the classes are subclasses of Polygon, which is a sequence of 3D vertex positions. There are classes for spherical and cylindrical projections of arbitrary 3D polygons.
Once a polygon is created, it is projected to 2D by using a camera (parallel for now), and then written to a SVG. All polygon derived classes objects are written as a path element in the output SVG file.
There are various figures defined in figures.cpp file. A figure (see class Figure) is a set of objects. When a figure is written to a SVG, the full file is created, including header (with the bounding box), and all SVG elements. There are various figures already defined, tailored for a specific paper.
A makefile is provided, which outputs the svg figures (target allsvgs). The makefile can also convert SVG files to PNG or PDF, by using the application rsvg-convert (available in macOS).
Here are some sample images obtained with the code:
