@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:
当前支持情况
enableCulling已支持,可以显著提升渲染性能。建议与替代方案
确认依赖版本:确保 @antv/g 和 @antv/g-canvas 均为最新版本。
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:
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:参考资料
如果仍有疑问或需进一步协助,请补充您的代码片段或 G 及相关依赖的具体版本号,方便我们进一步排查。
感谢您的反馈!

在最新版的G6图形库中

是遇到性能问题了么?
CodePangZ commentedon Nov 10, 2025
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
CodePangZ commentedon Nov 10, 2025
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。
wang1212 commentedon Nov 10, 2025
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。#1967

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。
