    @CodePangZ Hello! Here is an automated response to your question:

    Thank you for your feedback and for providing a screenshot.

    关于 enableCulling 在 Canvas 渲染器下失效的问题

    根据 官方文档,enableCulling(视锥体裁剪/视野裁剪)配置项理论上适用于所有 G 渲染器,但在部分实现中(尤其是 Canvas 渲染器),该特性可能尚未完全支持或存在限制。

    检查配置方式

    请确保您的初始化方式类似于以下示例:

    import { Renderer } from '@antv/g-canvas';
    
    const renderer = new Renderer({
      enableCulling: true, // 启用视野裁剪
    });
    
    const canvas = new Canvas({
      container: 'container',
      width: 600,
      height: 500,
      renderer,
    });

    当前支持情况

    • WebGL/WebGPU 渲染器:enableCulling 已支持,可以显著提升渲染性能。
    • Canvas 渲染器:部分版本可能尚未实现该优化,或效果不明显。建议查阅 release notes 或升级到最新版本进行验证。

    建议与替代方案

    1. 确认依赖版本:确保 @antv/g 和 @antv/g-canvas 均为最新版本。

    2. 切换渲染器:如需极致性能优化,可根据场景适时切换至 WebGL 或 WebGPU 渲染器:

      import { WebGLRenderer } from '@antv/g-webgl';
      canvas.setRenderer(new WebGLRenderer({ enableCulling: true }));
    3. 性能优化选项:Canvas 渲染器目前更推荐通过 enableDirtyRectangleRendering 等选项优化性能:

      const renderer = new Renderer({
        enableDirtyRectangleRendering: true,
      });

    在最新版的G6图形库中

    是遇到性能问题了么?

    渲染很多节点的时候有点卡,我想只渲染视口内的节点,所以想开启enableCulling

    我想弄清楚,因为会默认开启脏矩形优化,无论是否开启enableCulling,是不是都会只渲染视口内节点。

    我想弄清楚,因为会默认开启脏矩形优化,无论是否开启enableCulling,是不是都会只渲染视口内节点。

    如果是使用 G6,大量节点的拖拽交互性能不好的话,脏矩形优化机制没有意义,因为每个像素都会发生变化。 enableCulling 对该场景的性能改善比较有限,现在的性能瓶颈一部分原因在于 G 的核心渲染管线由于支持过多的特性导致了性能不佳,目前在持续做性能优化,有阶段性成果,但距离预期可能还有不小的差距。

    启用enableCulling 的话,初始渲染会只渲染视口内的节点,起码渲染速度变快了,但是我启用enableCulling ,似乎没有效果。
