The aim of this project is to generate artistic human-like drawn lines/curves.
While there is no precise metric yet discovered to differentiate between hand-drawn and computer-generated line drawings, humans can typically distinguish with ease the difference by a shear glance. The goal of this project is to produce lines that resemble human-drawn lines and may be used to replace traditional computer drawn lines.
Human drawn lines/curves seem more familiar and easy to understand than what computer drawn sharp and crisp line do. An example to illustrate the above is given below -
| Normal Lines | Line generated by application developed in this project |
|---|---|

The output/results of the application can be produced using OpenGl or SVG.
● Go to the "SVG" Folder.
● On terminal type the command : $ make
● If the command is successful, it will produce an executable named "ArtisticLines".
● Create a file in the same folder for giving the input points to the program or you can use the existing "points.txt" file.
● For running the executable, type this command in terminal : $ make run
● Now follow the instructions on the command file.
● After the program has finished, it will produce a file "outputSVG.svg" which can be viewed in the Chrome Browser.
● Go to the "OpenGl" Folder.
● On terminal type the command : $ make
● If the command is successful, it will produce an executable named "ArtisticLines".
● If the command fails, use the SVG method.
● Create a file in the same folder for giving the input points to the program or you can use the existing "points.txt" file.
● For running the executable, type this command in terminal : $ make run
● Now follow the instructions on the command file.
The application asks for the following parameters as input when the executable is run -
● Points Filename : Name of file that contains the input points to be given to the program.
● Final Time(tf) [<int> ideally 2] : Time value for the final hand position while drawing a line between a pair of points.
● dt (Δt) [<float> ideally 0.2] : Value for the time step Δt.
● Randomness (D) [<int> ideally 5] : Value for the deviation parameter squiggle.
● Spline Curve Parameter [<int> ideally 50] : The number of points to be plotted between pair of control vertices while
constructing the Catmull-Rom Splines.
● Line Width [<int> ideally 3] : Line Width that is used to draw in SVG.
