PointLightHelper.dispose()

The dispose() method is used in the PointLightHelper class of the three.js library. It is responsible for cleaning up the resources associated with a PointLightHelper object in memory when it is no longer needed. This ensures that the application does not run out of resources due to memory leaks.

Syntax

PointLightHelper.dispose()

Description

The dispose() method removes the PointLightHelper object's references from the memory. It also removes the associated data from the GPU memory. This frees up the memory used by the PointLightHelper object and improves the performance of the application.

Usage

var light = new THREE.PointLight(0xffffff, 1, 100);
var helper = new THREE.PointLightHelper(light, 1);
scene.add(helper);

// Use the PointLightHelper and the PointLight

// Remove the PointLightHelper
helper.dispose();

In the above example, we create a PointLight and a PointLightHelper object, adding the helper to the scene. We then use both the PointLight and the PointLightHelper in the application. Finally, we remove the PointLightHelper object from the scene by calling the dispose() method.

Conclusion

The dispose() method is an essential method for cleaning up the resources associated with a PointLightHelper object. It should be called whenever a PointLightHelper object is no longer needed, to free up memory and ensure the application runs smoothly.
