Compile with $ g++ source.cpp -std=c++11 -o tfv and execute with $ ./tfv. You'll be prompted for number of graduations (dimension of square aspect output) and number of frames (how many frames to render). Output will be that many .PGM images. Convert with ImageMagick $ convert -delay 1 anim*.pgm animation.gif.

A simple C++ program to visualize trigonometric functions. Along the x and y axes, the boundaries are clamped to -4..6 and -12..5 respectively. The z axis is used for animation and is clamped to 0..2*PI. The program will create an image frame of the function field over the xy plane using a z value of 0, then another using a z value of 2*PI / frames, where frames is the number of frames as user defined, then another frame using a z value of 2 * (2*PI / frames) and so on up until frames * (2*PI / frames) or just 2*PI. Ultimately, these frames can be packed into a .GIF using ImageMagick.

The function visualized is (cos(z) * ((0.5)*sin(x) + (0.5)*cos(y))) but this can be edited by the user.
