ImplicitPlotter

ImplicitPlotter is a command-line tool that can plot graph of any binary implicit function equation or inequality, supporting both Cartesian and polar coordinates.

The plotting algorithm is based on interval arithmetic.

Usage

Usage:

Example

Curve

ImplicitPlotter --relation "sin(x^2-y^2)=sin(x+y)+cos(x*y)" --output "./output.png" --width 1000 --height 1000 --xmin -10 --xmax 10 --ymin -10 --ymax 10 --drawColor "#0078D7"

Heart

ImplicitPlotter --relation "17*x^2-16*abs(x)*y+17*y^2+150/abs(5*x+sin(5*y))<225" --output "./output.png" --width 1000 --height 1000 --xmin -6 --xmax 6 --ymin -6 --ymax 6 --drawColor "#ED4336"

Face

ImplicitPlotter --relation "1/15*(6-y)+1/6400000*(8*x^2+4*(y-3)^2)^3+cos(max((x+y)*cos(y-x),(y-x)*cos(x+y)))<sin(min((x+y)*sin(y-x),(y-x)*sin(x+y)))" --output "./output.png" --width 1000 --height 1000 --xmin -8 --xmax 8 --ymin -5 --ymax 11 --drawColor "#366AAD"

Tai Chi

ImplicitPlotter --relation "(cos(a-r)-sin(a))*(r^4-2*r^2*cos(2*a+2.4)+0.9)+(0.62*r)^1000<0" --output "./output.png" --width 1000 --height 1000 --xmin -3 --xmax 3 --ymin -3 --ymax 3 --drawColor "#000000"

Pattern

ImplicitPlotter --relation "floor(sin(x+sin(y+sin(x))))=floor(cos(y+cos(x+cos(y))))" --output "./output.png" --width 1000 --height 1000 --xmin -10 --xmax 10 --ymin -10 --ymax 10 --drawColor "#E8AC4A"
