Detail Culling

A new DetailCullPlugin will accelerate camera interaction by culling less visually-interesting objects while the camera is moving.

For each Entity that represents an object in your Viewer, DetailCullPlugin will automatically mark it culled whenever

• the Entity is a certain IFC type, or
• the Entity is above a certain complexity and below a certain size.

When culled, an Entity is not processed by xeokit's renderer, leading to a significant speedup.

Use DetailCullPlugin by simply adding it to your Viewer.

const viewer = new Viewer({
    canvasId: "myCanvas",
    transparent: true
});
    
const detailCullPlugin = new DetailCullPlugin(viewer, {
    // TODO
});

const xktLoader = new XKTLoaderPlugin(viewer);

const model = xktLoader.load({
    id: "myModel",
    src: "./models/xkt/OTCConferenceCenter/OTCConferenceCenter.xkt",
    metaModelSrc: "./metaModels/OTCConferenceCenter/metaModel.json"
});
