Culling seems not working

[zhouccccc]

Hi, I created a map with pixi.js and this plugin. As the picture shown I create lots of points, each point is PIXI.Container (some sprites inside it )

According to the document, the less points shown, the higher the map rendering performance. but when I zoomed the map and let less points shown, I found that rendering performance has not improved (the FPS is low). I also log the culling

I believe this is a problem with my usage. The following is my code:

  const cull = new Simple({ calculatePIXI: true });
  cull.addList(viewport.children);
  cull.cull(viewport.getVisibleBounds());

  const callRender = () => {
    if (viewport.dirty) {
      cull.cull(viewport.getVisibleBounds());
      viewport.dirty = false;
      console.log(cull.stats());
    }
    renderer.render(viewport);
  };
  viewport.on('moved', callRender);

the function callRender is used for re-render map manually.

Could you please help me resolve this?

The code looks right. The culling results also look okay (although I guess you can count to find out for sure). Have you tried turning off culling and render 1300 objects? The performance problem may be with how you set up your objects instead of the culling. Culling doesn't guarantee good performance.

I tried turning off culling and render 1300 object just now, it seems okay. Maybe you are right, I will do some research on how to properly set up an object. Thank you
