shape drawing, rotation, scaling
Inviting desired shape easily, responsive design, rotation in several ways.
for calculations, it is possible to request and rewrite values with an external class call.
to draw a cube, declare class, call initialization method:
@Override
public void paintComponent(Graphics g){
super.paintComponent(g);
RotatingFigure rf = new RotatingFigure((Graphics2D) g, x, y, width, height, alfa);
rf.setDrawGuideLines(true);
rf.setColor(Color.BLUE);
rf.cube();
}Detail of drawing a cube shape:
public void cube(){
double beta =20;
CircleIntersectionPoint circle1a = new CircleIntersectionPoint(width, height, beta, xOrigo, yOrigo);
CircleIntersectionPoint circle1b = new CircleIntersectionPoint(width, height, (180-beta), xOrigo, yOrigo);
CircleIntersectionPoint circle2a = new CircleIntersectionPoint(width, height, (360-beta), xOrigo, yOrigo);
CircleIntersectionPoint circle2b = new CircleIntersectionPoint(width, height, (180+beta), xOrigo, yOrigo);
int widthc1 = (int) (circle1a.getxPoint()-circle1b.getxPoint());
int widthc2 = (int) (circle2a.getxPoint()-circle2b.getxPoint());
double[] xpoints = new double[]{circle1a.getxPoint()+x, circle1b.getxPoint()+x, circle2a.getxPoint()+x, circle2b.getxPoint()+x};
double[] ypoints = new double[]{circle1a.getyPoint()+y, circle1b.getyPoint()+y, circle2a.getyPoint()+y, circle2b.getyPoint()+y};
g2d.rotate(Math.toRadians(theta), (width/2)+x, (height/2)+y);
if(drawGL){
drawGuideLines(xpoints, ypoints);
}
g2d.setColor(color);
drawCube(widthc1, widthc2, xpoints, ypoints);
