This is a very simple function visualizer built with SDL2. It can show any function defined in the Function.cpp file.

To move around the graph use the left mouse button. To zoom the graph use the scroll wheel. To highlight a point use the right mouse button. To un-highlight double-click the right mouse button on the same spot.

You can alter the behaviour of the Visualizer by changing the values defined at the beginning of main.cpp and compiling.

To compile this application yourself you will need the packages: libSDL2-2_0-0, libSDL2-devel, libSDL2_ttf-2_0-0, libSDL2_ttf-devel. The default compiler is set to clang, however you can change this to gcc in the makefile.

To run the application you will need the packages libSDL2-2_0-0 and libSDL2_ttf-2_0-0. Execute the application in the same folder where the Hack-Regular.ttf file is located.

• Right now you have to "program" your desired function into Function.cpp.
• The sampling does not dynamically scale with the zoom. This is sort of on purpose, as I wanted to see the imperfections created by sampling.
• The offset_x and offset_y variables are inconsistent, which leads to some frustrating programming.
• It is not ideal that the executable has to be in the same folder as the font. Idealy a font from the users computer would get loaded.
