运行程序时处理停止

【中文标题】运行程序时处理停止

【英文标题】：Processing stalls when running a program

【问题描述】：

我试图编写一个程序来模拟地月系统，它运行了一段时间，但出乎意料的是，Processing 开始停止。每次我点击“运行”时，都会出现大约 10 秒的异常延迟，然后我的 Windows 11 任务栏通知我草图窗口已打开，但我无法访问它，并且没有任何显示。其他程序运行良好，包括使用 P3D 的程序。

这是我的代码：

PShape earth,moon;
void setup()

  size(6000,6000,P3D);
  PImage img = loadImage("earth.jpg");
  PImage img2= loadImage("moon.jpg");
  noStroke();
  earth=createShape(SPHERE,212.6); //radius of earth is 6378, sized down to by a factor of 30
  earth.setTexture(img);
  moon=createShape(SPHERE,57.9); //radius of moon is 1737, sized down by a factor of 30
  moon.setTexture(img2);

float z = -300; //transversal along z-axis
float angle; // angle of rotation wrt center
float rotAngMoon=6.68; //angle of moon's rotation
float rotAngEarth=23.5; //angle of earth's rotation
float inclination=5.14; //angle between moon's orbital plane and earth's orbital plane
float orbitDistEarth=155.6666; //distance from earth's center to barycenter (4670, sized down by a factor of 30)
float orbitDistMoon=1298.9; //distance from moon's center to barycenter (389670, sized down by a factor of 300)
void draw()

  background(0);
  translate(width/2,height/2,2*z);
  
  pushMatrix(); // Earth
  rotateY(27.321661*angle); //Earth spins faster
  translate(orbitDistEarth,0,0); //go to the point where earth would be
  rotateZ(rotAngEarth*PI/180); //rotate the earth
  shape(earth);
  popMatrix();
  
  pushMatrix(); //moon
  rotateY(angle);
  translate(-orbitDistMoon,(tan(inclination*PI/180))*orbitDistMoon*sin(angle*PI/180),0); //go to the point where the moon would be, additionally, the moon lies on a plane of inclination

//the line above might be incorrect with respect to the simulation, but I was debugging it when the stalls started occurring. There doesn't seem to be any error with it as far as I can see, so it should run fine

  rotateZ(rotAngMoon*PI/180); //rotate the moon 
  shape(moon);
  popMatrix();
  
  
  angle+=0.01;
  

对可能出现的问题有任何想法吗？

【参考方案1】：

由于 6000 宽和 6000 高的巨大窗口大小，您的系统已停止运行。这远远超过你在今天的屏幕上看到的（2021 年）。缩小窗口大小：

size(6000, 6000, P3D);

size(1920, 1280, P3D);

【讨论】：

成功了！不过，它之前并没有出现任何问题（尽管我必须手动调整窗口大小以适应我的屏幕）。不知道为什么突然觉得 6000*6000 太大了？

@NaN 可能是显卡驱动的问题，在 Windows 更新后。
