java - 创建一个 Squircle

Question

我是一年级程序员。我正在尝试创建一个 squircle。 (带圆角的正方形)。

到目前为止我已经成功了。我得到了 a、b 和 r 的常数。如果有人可以提供帮助，我将非常感激。我对此一无所知。所以要好:)

package squircle;

import java.awt.*;
import javax.swing.*;
import java.lang.Math;

public class Main extends javax.swing.JApplet {

  public void paint(Graphics g){

   // (x-a)^4  +  (y-b)^4  = r^4

   //    y =   quadroot( r^4 - (x-a)^4  + b)     
   // x values must fall within   a-r < x < a+r

    int[] xPoints = new int[200];
    int[] yPoints = new int[200];
    int[] mypoints = new int[200];

    for(int c = 0; c <200; c++){

       int a = 100;
       int r = 100;
       int b = 100;
       double x = c ;


       double temp = (r*r*r*r);
       double temp2 = x-a;
       double temp3 = ((temp2)*(temp2)*(temp2)*(temp2));
       double temp6 = Math.sqrt(temp-temp3);
       double y = (Math.sqrt(temp6) + b );
       double z = (y*-1)+300;

       mypoints[c]=(int)z;

    // if (c>100){
    //     y = y*1;
    // }
    // else if(c<100){
    //     y = y*1;
    // }

       xPoints[c]=(int)x;
       yPoints[c]=(int)y;


    // change the equation to find x co-ordinates 
    // change it to find y co-ordinates. 

    // r is the minor radius     
    // (a,b) is the location of the centre

    // a = 100
    // b = 100
    // r = 100
    // x value must fall within  0 or 200

    }

    g.drawPolygon(xPoints, yPoints, xPoints.length);
    g.drawPolygon(xPoints, (mypoints), xPoints.length);
  }
}

您没有使用 Graphics#drawRoundRect() 是家庭作业还是其他原因？
