DGraphX

This program is a simple and cute 2D and 3D grapher (to draw various 2d and 3d plots) from scratch. It doesn't have any dependencies at all. For creating graphics it uses only homebrewed C сode and X11 (main windowing system on UNIX-like systems). Grapher DGraphX is a very lightweight program and is capable of working on very slow devices (without any graphics accelerators).

Requirements

  • X11
  • С compiler (e.g gcc or clang)

Install

Clone this repo and make the executable file:

git clone https://github.com/davidmiheev/DGraphX
cd DGraphX
make

Usage

Run executable and enjoy:

./DGraphX

After that, you will be dealing with the GUI. The GUI is very modest, but (I hope) simple to understand. Important keyboard commands (program doesn't support mouse yet) for the 3D mode:

  • Use <- and -> keys for rotation about one of the coordinate axes
  • By default, the plot rotates about the Z axis, but you can change the axis: X key change to rotation about the X axis, Y key rotation about the Y axis, and Z key rotation about the Z axis.
  • If you want to see axes, just press Enter
  • Use Up and Down for changing the camera distance from the coordinate origin.
  • C key for zoom in, V key for zoom out.
  • You can also change the light source position: first press l key and change the position of the light source with <- and -> keys, then again press l key
  • You can also change the color method with L key (not l key)
  • To quit press q

Important keyboard commands (program doesn't support mouse yet) for the 2D mode: Coming soon...

Further Comments

Sad but to choose what specific plot you want to draw, you need to correct the code of functions that you want to plot in DGraphX.c and recompile, it needs to fix. Also, there is some wish to add mouse support and rewrite the program with the more modern technologies...
