Needle optimizes your 3D models using a combination of best practices and technology developed by us. We created a technique we call Progressive Loading to get your content on screen much faster. It functions similar to lazy loading for images on a webpage.

Instead of having to wait for the entire high-quality model to download, we create a number of progressively simplified versions upfront, that load almost immediately. Then, we continue downloading the higher-quality details in the background and seamlessly swap them in once they arrive.

This has a number of benefits:

• Your users see something sooner
  No more staring at blank spaces waiting for big files to finish downloading.
• Your application loads faster
  The overall experience is much more responsive, even on slower connections.
• High-quality details are preserved
  We’re not reducing the quality of your models - they stay as high-quality as you made them. Simplified versions are used during loading, or when users look at them from a distance, but as soon as they get close, we swap in the full detail version.

Think of it like loading an image on a webpage: you might see a somewhat blurry version first that quickly gets sharper. We bring that same instant preview experience to 3D models.
