(三)利用processing绘制简单规律图像

class DrawMap{

}
void draw_Round(){

smooth();
noStroke();
for(int y = 0; y <= height; y+=40){

fill(0, 125, 100);

}
}
}
void draw_Needle_Line(){
background(200, 140, 25);
smooth();
fill(102);
stroke(102);
for(int y = 20; y <= height-20; y+=10){
for(int x = 20; x <= width-20; x+=10){
ellipse(x, y, 4, 4);
line(x, y, width/2, height/2);
}
}
}
void draw_Net_Point(){
background(0);
smooth();

for(int y = 32; y <= height; y += 8){

}
};

void setup(){

}
void draw(){

map.draw_Round();
//map.draw_Needle_Line();
