Three.js Cookbook

Waiting until resources are loaded

In the Load resources asynchronously recipe, we showed how you can load external Three.js resources asynchronously. For many sites and visualization, loading resources asynchronously is a good approach. Sometimes, however, you want to make sure that all the resources you require in your scene have been loaded beforehand. For instance, when you're creating a game, you might want to load all the data for a specific level beforehand. A common method of loading resources synchronously is nesting the asynchronous callbacks we've seen in the previous recipe. This, however, quickly becomes unreadable and very hard to manage. In this recipe, we'll use a different approach and work with a JavaScript library called Q. ...
