How do we make your 3D models load faster?

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.

What are the core technologies behind Needle Engine?

Needle Engine brings together several key technologies that are required to build today's modern 3D web apps.

Development Environment: Needle Engine is built with TypeScript, and uses vite and node.js as development environment. This allows you to use hot reloading and fast iteration speeds, similar to other modern web development frameworks.
Rendering: Needle uses the popular three.js library for rendering.
Component System: Needle provides a component-based architecture for building interactive experiences. This allows you to create reusable components and attach them to objects in your scene, similar to other game engines.
- Built-In Functionality: Needle Engine provides many built-in components that can be used to create interactive experiences. These components are designed to be easy to use and can be added to objects in your scene without writing any code.
- Physics: We use Rapier.js for physics simulation, which is an efficient physics engine that works well in the browser.
- Networking: Needle Engine has built-in networking capabilities, powered by WebRTC and Peer.js, running on our own networking stack.
- Custom Components: New components can be created in TypeScript or JavaScript. We automatically generate UI for Unity and Blender so that you can easily assign and configure them in the editor.
Data: The core asset format we use is glTF 2.0. Beyond the standard glTF features and Khronos extensions, we're using custom extensions (called vendor extensions) to store rich scene and component data like lighting settings, physics data, audio, video and much more.
Integrations: Needle Engine has integrations for Unity and Blender, which allow you to create and export 3D scenes directly from these applications. The integrations provide a seamless workflow for artists and developers, allowing them to use the tools they are already familiar with while taking advantage of the powerful features of Needle Engine.

I need high-quality visuals. Is that possible on the web?

Yes. Needle Engine fully supports Physically-Based Rendering workflows (PBR). We support many sophisticated glTF material extensions like clearcoat, transmission, IOR, specular, iridescence, anisotropy, volume and dispersion for rich visual effects and realistic results.

Needle also provides fine-grained control over lighting and shadows of your scene and assets. You can use modern tonemapping algorithms like AgX and ACES, and add a wide range of post-processing effects like bloom, depth of field, color grading, and more to your scene.

Can I use visual shader tools like Unity's Shader Graph?

Yes, when using the Unity integration, custom unlit shaders created with Shader Graph can be exported to the web, allowing artists to create custom visual effects without writing code.

Please vote for MaterialX support in Needle Engine for even more seamless workflows.

How does Needle Engine handle light, shadows, and lightmaps?

Needle Engine supports image-based lighting, real-time light sources and baked lighting. Image-based lighting (IBL) uses high-dynamic-range (HDR) images to create realistic lighting and reflections with near-zero performance impact. It can be used with or without real-time lights. Real-time lights can be point, spot, or directional light sources.

Needle also allows fine-grained control over shadows, including enabling shadow casting and receiving on a per-object basis. Lightmaps can be baked and exported from our Unity and Blender integrations.

Additionally, reflection probes are also supported, and you can add post-processing effects like bloom, depth of field, and color grading to enhance the visual quality of your scenes.

Can I create collaborative apps or multiplayer games with Needle?

Yes. Networking is a built-in feature in Needle Engine, and many of our components support networking out of the box. Our networking stack can be used at no additional cost across all supported platforms.

We provide both no-code components and scripting APIs for creating multi-user experiences with synchronized world states, networked objects, persistent storage, and integrated voice chat and screensharing capabilities.

These features allow creating real-time collaborative applications, virtual worlds, multiplayer games, and other interactive experiences where multiple users can interact with the same 3D environment, or where a user can come back to the same state of the world later.

Does Needle Engine support Augmented Reality on Android and iOS?

Yes. Needle Engine supports AR on Android and iOS right from the browser. Where available, we use WebXR, which brings VR and AR to browsers on devices like Android phones and Quest headsets. For iOS devices, which currently lack WebXR support, we convert your scene on-device to interactive USDZ, the format required for Apple QuickLook.

Our Everywhere Actions allow creating interactive apps for all platforms without writing any code.

chevron_right

What are Everywhere Actions?

Everywhere Actions are components that ship with Needle Engine and are available in the Unity integration. They allow creating common interactions, like playing audio or animations on click, changing materials, toggling visibility or having objects look at the camera, without writing code.

They are called Everywhere Actions because they work on all platforms, including the limited interactivity environment of iOS AR (QuickLook/USDZ).

Learn More: Everywhere Actions

chevron_right

Does Needle Engine support physics simulation?

Yes, Needle Engine includes support for real-time physics simulation. You can add Rigidbody components and various collider types (box, sphere, mesh) to objects within the Unity or Blender integrations, and these physics properties will be exported and simulated in the web runtime.

chevron_right

Can I use animations and sequencing in Needle Engine?

Yes. Needle Engine allows for animation workflows ranging from simple object animations, over character state machines, to choreographing and sequencing many different clips and assets.

You can animate characters, lights, cameras, component properties, and materials. When using the Unity integration, both Animator controllers (for state machines) and Timelines (for sequencing) are exported into web-ready formats, including Animation, Audio, Activation, Control, and Signal tracks. Some features are limited, like blend tree and sub-statemachine support.

Technically, animation in Needle Engine is made possible by the KHR_animation_pointer glTF extension and our own extensions for timelines, sequencing, audio, video and more.

chevron_right

Can I write custom code or make my own components?

Yes! Needle Engine uses a component-based workflow. You can create custom components using TypeScript or JavaScript, and attach them to objects in your scene.
When using the Unity/Blender integration, there's a system where you write TypeScript code, and a compiler automatically generates corresponding C# components / panels in Unity/Blender for easy assignment and property inspection in the editor. This allows you to leverage the editor's visual tools while still writing custom logic in TypeScript.

chevron_right

Do I have to write code to work with Needle Engine?

No. Needle Engine is designed to be accessible to artists and developers alike. You can create interactive experiences using Visual Tools like our Unity and Blender integrations, and use Everywhere Actions for common interactions without writing code. A lot of projects can be made without any coding at all.

If you want to create more complex interactions, you can write custom scripts in TypeScript or JavaScript. Our scripting API is designed to be intuitive and easy to use, even for those new to programming. We also provide AI assistance for coding help, and a lot of examples to get you started.

chevron_right

How does Needle Engine make projects load so fast on the web?

Needle Engine incorporates an automatic optimization pipeline. This optimization pipeline can improve load times tremendously, even for very complex scenes, without you having to do anything.

Here's how it works:

We automatically create multiple levels of detail (LODs) for all meshes and textures in your scene. These LODs are in separate files, so they can be loaded progressively. This means that when a user first loads your scene, they see a low-resolution version of the model, and as they get closer, the higher-resolution versions are loaded in the background.
We compress all 3D assets using state-of-the-art, industry-proven compression algorithms like Draco for meshes and KTX2 or WebP for textures. Together with progressive loading, this ensures faster load times, vastly lower memory usage, and better runtime performance.
At runtime, we use GPU instancing and automated batched rendering for additional performance.

Where can I host apps made with Needle?

Apps made with Needle can be hosted anywhere. Needle Engine projects are often static web sites – that means they don't require any server code, only file hosting. So projects can be deployed wherever you can host files, for example on a web server, cloud storage, or hosting platform. Of course, you can also bring your own server-side code.

Needle Cloud is our recommended hosting solution, designed to work seamlessly with Needle Engine. It includes a Content Delivery Network (CDN) for fast global access. It also provides easy deployment options from Unity and Blender, and allows managing 3D assets and web apps with your team.

Other options include:

Hosting Services: Services like Needle Cloud, Netlify, Vercel, GitHub Pages, Cloudflare Pages, itch.io, or Glitch are excellent choices and often have free tiers. Needle's editor integrations include direct deployment options to some of these services.
Cloud Storage: Cloudflare R2, AWS S3, Google Cloud Storage, Azure Blob Storage and others can serve pages globally via CDN, similar to Needle Cloud.
Web Servers: Deploy to Apache, IIS, or other servers capable of serving static content.
On-Premises: You can host apps made with Needle on your own servers and infrastructure.
As part of other websites: You can seamlessly integrate Needle within existing web applications made with any framework – React, Vue, Angular, Svelte, Next.js, etc.

chevron_right

Can I integrate OAuth or other authentication methods?

Yes. Needle Engine runs as part of a standard web page or web application. It does not handle authentication directly, but you can implement authentication using standard web practices and connect it to your app.

How it works:

Your surrounding web application – the page where Needle is used – handles the authentication flow (e.g., redirecting to an OAuth provider like Google, Azure AD, Auth0, Okta; or handling JWT tokens).
Once the user is authenticated, your application's frontend code has access to user information or tokens.
You can use this authentication status to:
- Control access to the Needle Engine experience itself.
- Pass user information or tokens to Needle Engine components and scripts if needed, for example to personalize the experience or make authenticated API calls from within the 3D scene
- Secure backend API calls made from your Needle application using bearer tokens or session cookies.

Essentially, Needle Engine operates within the security context established by your broader web application.

chevron_right

Can Needle Engine connect to backend databases or APIs?

Yes. Needle Engine applications are web applications running JavaScript in the browser. You can use standard browser APIs like fetch() or libraries like axios within your custom Needle Engine components to:

Fetch data from any RESTful API, GraphQL endpoint, or similar
Send data back to your servers, for example to save user progress, submit high scores, update state.
Connect to backend services for real-time updates using WebSockets or other protocols if needed.

Your backend can be built with any technology (Node.js, Python, Java, .NET, etc.) and connect to any database (SQL, NoSQL). Needle Engine interacts with it via standard web API calls.

For some of your backend needs, Needle's built-in networking might already be enough – for example, for storing a persistant world state across sessions. Consult the documentation for more details on how to choose the right approach for your use case.

Can Needle Engine scale to many users? What about multiplayer?

Yes. Scalability involves multiple aspects:

Website Load Times: Needle uses best practices for the modern web and modern formats, like compressed glTF and progresssive loading, to optimize load times and rendering performance. This means that many users can simultaneously access websites made with Needle, same as other static websites. Using a CDN like Needle Cloud improves load times for globally distributed users as well.
Rendering Performance: Performance depends on scene complexity, target hardware, and optimizations. Needle builds on Three.js, benefiting from its performance characteristics. Needle does many optimizations out of the box, and you can additionally optimize your assets within Unity or Blender (reducing triangle count, draw calls, texture sizes) if needed.
Networking and Multiplayer: Needle's built-in networking uses WebRTC (PeerJS), which is suitable for shared sessions with ~16-32 concurrent users, depending on scene complexity and server performance. For larger-scale concurrency (hundreds/thousands of users), you would typically need a dedicated server architecture or integrate with third-party scalable networking solutions. Needle's networking components might serve as a starting point and you can later switch to solutions for massive-scale scenarios if needed.
Backend Scalability: If your application relies heavily on server-side code, the scalability of that backend infrastructure is a separate but critical factor for handling many users. This depends on your backend technology and architecture. For example, using serverless functions or microservices can help scale your backend to handle many concurrent users.

Can I use Needle Engine for tradeshows or other areas with limited internet access?

Yes! Through Progressive Web App (PWA) capabilities, your Needle app can run even without internet, and even be installed on devices if needed.

The typical workflow:

Create your app using Needle Engine.
Add the Needle PWA plugin.
On the presentation device (kiosk, tablet, PC), open the application's URL once while online. All assets will automatically be cached.
The device can now be taken offline. The PWA will run reliably from the local cache, providing a seamless experience. You can also install the PWA on the device – adding it to the home screen or desktop – for easier launching.

Can apps made with Needle run without internet access?

Yes, apps made with Needle Engine can be configured to run offline by turning them into Progressive Web Apps (PWAs), or by embedding them in native frameworks like Flutter.

With a single line of code, you can turn your app into a PWA, which allows it to be run offline and even be installed on devices. This is done by leveraging the browser's capabilities to cache assets and serve them locally – battle-tested technologies that most browsers have adopted. Service workers and the Cache API allow fine-grained control over what gets cached and when, so you can ensure that your app is always available, even without an internet connection.

Here's the concept:

You enhance your Needle Engine web project with PWA capabilties. This adds a Service Worker and a Web App Manifest.
When a user visits online for the first time, the Service Worker installs and caches the app's assets.
On subsequent visits, even without internet, the Service Worker serves the cached files, enabling offline operation. The PWA can also be installed by users for easier access.
If needed, this PWA can be wrapped in a native app container (like Tauri, Electron, Capacitor or Trusted Web Apps) for distribution through app stores.
