Java-Function-Grapher

Screen.Recording.2022-11-06.at.8.20.54.PM.mov

Features

• zoom towards mouse pointer using scroll wheel
• transalte using WASD
• Input n dimesional power equations using java scanner
• Overide equation reader to graph custom functions such as sin or cos with ease
• Seperation of math and graphics
• graphs min and max points

How To Enter Your Own Equations

first go to the manager script and set 'userInputOverride' to true

private boolean userInputOverride = true; //like this

then go to the 'rawEquation' function and enter your function as shown below:

public double rawEquation(double input){
		double output = 0;
		if(userInputOverride){
			//type your equation here as output = 'input'
			//here is an examples:
			output = Math.sin(input/10)*10; //'y=sin(x/10)*10'
		}else{
			for(int x = 0; x < equationVariables.size(); x++) {
				output += equationVariables.get(x) * Math.pow(input,x);
			}
		}
		return (output);
	}

Problems

• min and max point no longer have worldspace accuracy
• if you zoom to far out everything breaks

Areas for Inprovment

• graphspace to worldspace should be done with a static well defined function
• add ability to graph more than just functions such as circles
• display area under curve rather than print it out
• display function rather than print it out
• graph multiple functions
• make more intuitive input
• re-impliment linear and logistic regression
• zooming twords mouse should be done with matrix math
• grid lines should be infinitly zoomable in and out (codded algorthimicaly rather than hard coded)
