About

    A library for plotting 2D graphs of mathematical equations and some curved geometric shapes using only vectors. This is not an advanced library but it has some cool features and easy-to-use if your need is simple.

    This was a university project in 2018-2019 spring semester. Challenge of the project was using only vectors so that's why this library implemented using just vectors.

Code Example

Figure *fig;
Color c = {.red = 80, .green = 20, .blue = 0};

fig = start_figure(10, 10);
set_thickness_resolution(fig, 0.05, 1000);
set_color(fig, c);

draw_fx(fig, your_function, -10, 10);
export_eps(fig, "filename.eps");

Features

  • Capable of drawing equations with one input
  • Draws ellipse, circle, polyline
  • Resizable paper size
  • Resolution, color and thickness settings
  • Takes domain of a function
  • Scaling
  • Resizing
  • Appending
  • Exporting to SVG and EPS files
  • Importing from SVG files

Setup

  1. Clone this repository to your project.
  2. Give -Iinclude option to your compiler.
  3. #include <RPS/libvector.h> in your file.
  4. Compile src/libvector.c and give object file to your linker.

Demo

    You can follow comments in file test/driver.c for demo instructions.

  • To run demo, type make in the main folder where you cloned this repository.
  • A folder will be created named demo where you can see exported graphs.
  • Type make clean if you want to remove generated demo files.
