PointsMaterial

Extends:

ComponentMaterial → PointsMaterial

Configures the size and shape of "points" geometry primitives.

Usage

In the example below, we'll customize the Scene's global PointsMaterial, then use an XKTLoaderPlugin to load a model containing a point cloud.

[Run this example]

import {Viewer} from "../src/viewer/Viewer.js";
import {XKTLoaderPlugin} from "../src/plugins/XKTLoaderPlugin/XKTLoaderPlugin.js";

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

viewer.scene.camera.eye = [0, 0, 5];
viewer.scene.camera.look = [0, 0, 0];
viewer.scene.camera.up = [0, 1, 0];

viewer.scene.pointsMaterial.pointSize = 2;
viewer.scene.pointsMaterial.roundPoints = true;
viewer.scene.pointsMaterial.perspectivePoints = true;
viewer.scene.pointsMaterial.minPerspectivePointSize = 1;
viewer.scene.pointsMaterial.maxPerspectivePointSize = 6;

const xktLoader = new XKTLoaderPlugin(viewer);

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