To modify symbols on the OpenLayers WebGLPointsLayer, you can use the following methods:
Adding symbols: You can add symbols to the layer by adding new features to its source. For example, you can create a new feature with a different symbol and add it to the source using the addFeatures() method.
Removing symbols: To remove symbols, you can use the removeFeature() method to remove the feature with the symbol that you want to remove.
Changing symbols: To change symbols, you can modify the style of the feature. You can create a new style and assign it to the feature using the setStyle() method.
Here is an example of how to modify the symbol of a feature on the WebGLPointsLayer:
const style = new Style({
image: new Circle({
radius: 5,
fill: new Fill({
color: "#ffcc33",
}),
}),
});
const feature = new Feature(new Point([0, 0]));
feature.setStyle(style);
const source = new VectorSource({
features: [feature],
});
const layer = new WebGLPointsLayer({
source: source,
});
// Modify the symbol of the feature
const newStyle = new Style({
image: new Circle({
radius: 10,
fill: new Fill({
color: "#ff0000",
}),
}),
});
feature.setStyle(newStyle);
