Comparing WebGL Frameworks for Complex 3D Product Configurators

The Journey of Finding the Right Stack for Manufacturing Configurators

In the manufacturing and industrial sector, complex custom products are increasingly being sold through interactive 3D product configurators. This is an early trend but its becoming a powerful differentiator when there are three to four main competitors in a given landscape.

These digital tools allow customers to visualize and customize products, leading to improved new customer education, fewer specification errors, higher overall satisfaction, and more efficient sales processes. We also see sales reps being able to run through configurator work with clients onsite as putting them head and shoulders above competitor sales presentations.

For manufacturers selling complex solutions—like (ehem!) custom products with a series of variations across a series of product families—implementing an effective configurator requires the right tech stack selection. The configurator must:

1. efficiently render detailed 3D models
2. handle multiple interactive configurations
3. integrate with existing systems
4. maintain performance across devices

We did a lot of that legwork so hopefully you have to do less and can make a more informed decision. Below guide compares the top technology stacks for building browser-based 3D product configurators, analyzing their strengths and limitations for complex design and/or custom manufacturing applications.

We are not biased to any solution at this point. I will say that React Three Fiber (R3F) does emerge as a strong contender for many use cases, and therefore requires some extra attention; but we explore all viable options to help you make an informed decision based on your specific requirements.

Understanding WebGL-Based 3D Technologies

The foundation for browser-based 3D graphics is WebGL, a JavaScript API that renders interactive 3D graphics without plugins. On top of WebGL, developers have created higher-level libraries and frameworks that simplify 3D development. Current major contenders include:

• Three.js – A popular JavaScript 3D library
• Babylon.js – A full-featured JavaScript 3D engine
• PlayCanvas – A web-first 3D engine with a collaborative editor
• Unity WebGL – A game engine that can export to WebGL

When integrated with React, these technologies form the basis for powerful product configurators that can be embedded seamlessly within modern web applications.

Comparing 3D Rendering Enginesduct team is like

Selecting the right rendering engine is the most critical decision when building a 3D configurator for complex manufacturing products. Each engine offers different capabilities, performance characteristics, and integration options.

Three.js — The Flexible WebGL Workhorse

Three.js is the oldest and most widely adopted WebGL library, often considered the de facto standard for web 3D development.

Three.js provides a straightforward API that abstracts WebGL, allowing developers to create scenes with meshes, cameras, lights, and materials. Its popularity is evident with significantly higher Google Trends interest than competitors (HT Spot Virtual, but US trends below show even greater difference).

So another consideration is cost to service a Babylon JS app over time.

Babylon.js — The Batteries-Included Engine

Babylon.js positions itself as a more feature-rich engine with “batteries included” — many features that would require external add-ons in Three.js come built-in.

Babylon’s out-of-the-box capabilities mean developers can achieve complex results with less custom code. For example, Babylon provides a ShadowGenerator class to handle shadows and multiple light setups more granularly (again, HT Spot Virtual).

PlayCanvas — The Web-First Game Engine

PlayCanvas is a 3D engine designed specifically for the web, with a cloud-based editor for building scenes and game logic.

PlayCanvas is known for being lightweight and performant, with a runtime performance similar to Babylon’s. Its visual editor can significantly speed up development, especially for teams with artists and designers (via Stackshare).

Unity WebGL — The Powerhouse (with a Price)

Unity is a leading game engine that can export projects to WebGL via WebAssembly.

Unity WebGL exports are notably bulky, with even simple scenes potentially resulting in multi-megabyte downloads. A basic Unity WebGL demo might produce ~4.6 MB of WebAssembly code and ~12 MB of binary data, compared to about 1 MB total for a Three.js app of similar content (see threejs.org forum for more there).

Note on Imperative vs Declarative integration

• Declarative: The 3D scene is integrated directly with the React tree (React Three Fiber, react-babylonjs).
• Imperative: The 3D engine runs as an embedded layer (PlayCanvas, Unity), and React communicates with it manually.

React Integration Strategies for Manufacturing Product Configurators

For manufacturing product configurators that often require complex UI controls and extensive form validation, seamless integration with React can be a critical factor. Each 3D engine has different approaches to React integration, with varying degrees of complexity and elegance.

React Three Fiber (R3F) — Declarative Three.js in React

React Three Fiber has become the most popular solution for integrating Three.js with React. It’s a custom React renderer that allows developers to use Three.js in a declarative, React-friendly way.

Key Benefits for Manufacturing Configurators:

• Seamless integration with React’s rendering lifecycle and state management
• Components can directly react to complex configuration rules and constraints
• Support for React hooks and suspense (crucial for loading heavy industrial models)
• Vibrant ecosystem (@react-three/drei provides many helpers and components)
• Ability to leverage existing React state management solutions (Redux, Zustand, etc.)

With R3F, you can write <mesh> in your React code, with children and props corresponding to Three.js objects, and R3F handles adding those to the Three.js scene. For a complex manufacturing configurator with many UI controls and validation logic, this means your 3D scene can react to state changes just like any other React component.

// Example of React Three Fiber component for a configurable industrial product
function ConfigurableProduct({ color, material, variant, dimensions, attachments }) {
  // Product configuration logic can be handled with React hooks
  const { isValidConfiguration, validationErrors } = useConfigValidator(
    variant, dimensions, attachments
  );
  
  return (
    <group>
      {/* Main product model */}
      <Suspense fallback={<LoadingSpinner />}>
        <Model url={`/models/${variant}.glb`} scale={dimensions.scale} />
      </Suspense>
      
      {/* Conditional rendering of attachments based on configuration */}
      {attachments.map(attachment => attachment.enabled && (
        <Attachment key={attachment.id} type={attachment.type} position={attachment.position} />
      ))}
      
      {/* Material updates based on selection */}
      <mesh geometry={baseGeometry}>
        <meshStandardMaterial 
          color={color}
          metalness={material === 'metal' ? 0.8 : 0.1}
          roughness={material === 'glossy' ? 0.1 : 0.7}
        />
      </mesh>
      
      {/* Visual indication of validation errors */}
      {!isValidConfiguration && <ValidationErrorHighlight errors={validationErrors} />}
    </group>
  );
}

React Integration for Babylon.js — react-babylonjs

While Babylon doesn’t natively have a React renderer, the community has created react-babylonjs — a library analogous to R3F that wraps Babylon.js in a React-friendly way.

This library allows declarative scene construction with JSX, covering most of the Babylon.js API. With react-babylonjs, you can achieve a similar level of integration as R3F provides for Three, though with a smaller community and fewer examples to draw from.

PlayCanvas with React — Embedded Approach

PlayCanvas does not have a dedicated React renderer library. The typical pattern is to embed the PlayCanvas application in a React component and establish communication channels between the React UI and the 3D scene.

This approach typically involves adding a container <div> in React and then, on component mount, initializing the PlayCanvas engine and loading the scene.

Communication between the React UI and the 3D scene happens via PlayCanvas script events or the global context, which can become complex for intricate manufacturing configurators with many interdependent parts. I can just imagine the headache of major product changes that affect multiple product lines in getting everything hand integrated as part of ongoing support.

Unity with React — Separated with Bridge Communication

Unity has no direct integration with React. The primary method is embedding the Unity WebGL build into a React app using utilities like react-unity-webgl, which help manage loading the Unity loader script and canvas as a React component.

Once running, you can send data to Unity by calling functions like unityInstance.SendMessage(gameObjectName, methodName, data) and receive data via calling JS functions from C#. Definitely cumbersome than pure js libraries, as you’re managing Unity runtime and the DOM.

In my mind its a moot point — unless you need ultra sleek or high intricacy visualizations. If the visualization requires capabilities far beyond what WebGL libraries can provide, or if the 3D assets will also be used in non-web environments like VR training or native applications, then it’s a strong option. Otherwise feels like overkill.

Animation Libraries and 3D Interactivity

Animating 3D product models significantly enhances the user experience of a configurator. There are several approaches to handling animations in a web 3D context:

GreenSock Animation Platform (GSAP)

GSAP is a powerful JavaScript animation library known for its performance and flexibility. It operates imperatively — you define timelines or “tweens” in code.

I spent a year learning GSAP when it came out. As a fun aside (for me) this is my “most viewed” animation:

See the Pen GSAP Mountain Range Perspective Shift Change on Load by jim (@jimthornton) on CodePen.

GSAP Mountain Range Perspective Shift Change on Load by jim (@jimthornton)

I thought it was going to be the end-all be-all for web animation so I spent 6 months on the side building a goofy website that I never launched with it.

In a Three.js context, you might grab a reference to a mesh or camera using useRef in R3F, then use gsap.to(ref.current.position, { x: 10, duration: 1 }). GSAP works outside of React’s rendering cycle, directly manipulating Three.js objects.

React Spring.. Honorable Mention?

React Spring is a popular animation library in the React ecosystem that uses spring physics to create natural-feeling animations.

In a React Three Fiber context, React Spring works hand-in-hand (R3F even re-exports some Spring utilities) — enabling you to animate Three.js object properties as part of the React render loop:

const props = useSpring({ 
  rotation: active ? [0, Math.PI/2, 0] : [0,0,0] 
});
return <a.mesh rotation={props.rotation} />;

React Spring is well-suited for interactive transitions, such as rotating a product to a new angle when the user selects a different view, or smoothly morphing between colors and materials.

Engine Native Animation Systems

Both Three.js and Babylon.js include built-in animation capabilities:

Three.js Animation:

• AnimationMixer can play skeletal animations or morph target animations from loaded models
• Basic keyframe tweening via the .animate function or manual updates
• No high-level timeline API like GSAP

Babylon.js Animation:

• Robust system with Animation objects for properties
• Support for keyframes and easing functions
• Scene-level animation management via beginAnimation()

Animation Approach	Integration Style	Strengths	Use Cases in 3D Configurator	Notes on Performance
GSAP (GreenSock)	Imperative (external lib) – timeline & tweens on JS objects	Extremely fine-grained control; timeline sequencing; robust easing; works outside React (no re-renders)​ via @designspluscodes on Medium	Complex choreographed animations (e.g., an intro sequence or multi-step part swap). Animating multiple properties or objects in sync (camera + model + UI).	Highly optimized for large numbers of tweens via Creole Studios. Minimal impact on runtime.
React Spring	Declarative (React hooks) – spring physics interpolation	Natural, fluid transitions with minimal config; tied to React state (easy to trigger via state changes)​ via Creole again.	Interactive state-based animations (e.g., smooth movement when user selects something, hover effects on 3D objects). Small iterative animations (rotation, position, material changes) that should react to user input.	Very efficient for moderate elements. Part of React render loop – great for <= dozens of objects; but heavy use (hundreds of springs) less ideal than GSAP​
Engines’ Built-in	Depends on engine (keyframes, skeletal animations, etc.)	Leverages engine capabilities (GPU skinning for skeletal anims; author animations in 3D tools). No extra lib needed.	Playing pre-authored animations (open/close, moving parts). Simple repetitive motions (spin, bob) via frame updates. Physics-based motions (e.g., drop an object) using engine physics.	Excellent for skeletal/morph animation (runs on GPU). Simple property animations are fine, but complex sequences are harder to manage than with a dedicated lib.

3D Model Loading and Optimization

Efficiently handling 3D assets is crucial for performance and user experience in a product configurator. The chosen stack must support modern model formats and provide optimization techniques.

glTF — The “JPEG of 3D”

The glTF 2.0 format has become the standard for delivering 3D models on the web:

• All major engines (Three.js, Babylon.js, PlayCanvas) have strong glTF support
• Compact format that uses binary chunks for geometry
• Includes PBR material definitions that map well to engine materials
• Perfect for storing product variations with high-quality materials

For a product configurator, glTF is ideal to store each product or part variation, complete with materials and even variant definitions.

Draco Mesh Compression

Draco is an open-source geometry compression library that dramatically reduces the file size of 3D meshes:

• Can reduce mesh sizes by up to 90%
• Supported by Three.js, Babylon.js, and (with extra setup) PlayCanvas
• One user reported compressing models from 100MB to 3MB (via babylon forum).

The cost of Draco is that decompression happens on the client via a WebAssembly or JS decoder, which can add processing time. Generally, this trade-off is worthwhile when network speeds are the bottleneck.

Level of Detail (LOD) and Mesh Simplification

For responsive performance across devices, LOD techniques are essential:

Babylon.js offers built-in LOD support and even an in-browser mesh simplification tool. Its mesh.simplify() function can generate lower-poly approximations of a mesh on the fly see babylon docs.

Three.js supports LOD by allowing you to attach multiple versions of a mesh at different detail levels, but doesn’t provide an automatic simplifier in the core.

Material and Texture Variants

A common scenario in product configurators is changing materials or colors:

• The glTF ecosystem includes an extension called KHR_materials_variants which allows multiple material sets in one glTF
• Both Babylon.js and Three.js support this extension
• Enables switching between material variants (e.g., 5 color options) without loading separate model files

Loading and Caching Strategies

For a configurator with many variants, intelligent asset loading is critical:

• All engines support asynchronous loading of models
• Consider preloading the most common variants
• Implement proper resource disposal when variants are no longer needed
• Use loading indicators or low-detail placeholders during loading

Optimization Pipeline

From original 3D model → glTF conversion → Draco compression → LOD generation → final optimized assets

Performance Considerations for Manufacturing Product Configurators

Performance is particularly critical for manufacturing product configurators, where complex models with high detail levels must remain responsive across various devices, including sales representatives’ tablets in the field.

Rendering Performance for Complex Industrial Models

In terms of raw WebGL rendering capability for detailed manufacturing products:

Three.js and Babylon.js are roughly equivalent in rendering performance. Both can handle complex models with tens of thousands of polygons while maintaining good frame rates when properly optimized. As Andrei Stepanov on babylon forum noted, “neither is going to impose an upper ceiling on the performance of your project”.

The difference lies in default settings and optimization approaches:

• Three.js starts minimal and you add what you need, resulting in potentially better performance by default but requiring more manual optimization.
• Babylon.js has more features enabled by default (like picking for interactive elements) which might need tuning for max performance.
• PlayCanvas has historically prioritized performance and I think of as for more sleek marketing visualizations. Its auto batching and optimization can be good for complex product scenes.
• Unity WebGL provides advanced rendering capabilities, but the WebAssembly layer adds a fair amount of overhead. For very complex industrial machinery with numerous moving parts and high poly counts, this overhead might be justified by Unity’s advanced capabilities, but for most configurators, the performance trade-offs aren’t worth it.

Load Time and Initial Experience

For manufacturing customers, long initial load times can significantly impact adoption:

• Three.js/React Three Fiber: 0.5-1MB core library + your application code
• Babylon.js: ~2MB (though tree-shakable to smaller size)
• PlayCanvas: Similar to Three.js when using just the engine
• Unity WebGL: Much larger initial download (typically ~15-30MB)

Progressive Loading Strategies:

• Three.js/R3F and Babylon.js: Both support progressive loading where a low-detail model appears quickly and details stream in
• PlayCanvas: Good support for asset streaming and prioritization
• Unity WebGL: More challenging to implement fine-grained progressive loading

Manufacturing Context Impact: Field sales reps can operate in more rural areas with variable connectivity. A configurator that loads quickly with a base model, then progressively enhances detail, provides a better experience than one that forces the user to wait for a complete download.

Memory Usage for Product Variant Management

Managing dozens or hundreds of product variants requires careful memory management:

• Three.js/Babylon.js: Give developers fine-grained control over what models are loaded and unloaded
• PlayCanvas: Good memory management with its asset system
• Unity WebGL: Higher baseline memory requirements, which can be problematic on mobile devices

Strategic Considerations for Manufacturing Configurators:

1. Component Reuse: For modular products, reusing component geometries across variants
2. Texture Atlasing: Combining multiple material textures into larger optimized textures
3. Instance vs. Separate Models: Using instancing for repeated components rather than separate meshes

Performance a la Manufacturing Use Cases

Heavy CAD Models: Manufacturing configurators often start with CAD data that must be significantly optimized:

• Three.js/Babylon.js: Require external decimation tools before import
• PlayCanvas: Similar to Three.js/Babylon.js for optimization requirements
• Unity: Has some built-in decimation tools but still requires pre-processing

Complex Material Representations:

• Three.js: Excellent PBR material support for realistic metals, plastics
• Babylon.js: Possibly stronger built-in material system with less setup
• PlayCanvas: Strong PBR support
• Unity: Most advanced material options, but at a performance cost

Assembly Visualization Performance:

• Three.js: Requires custom implementation for complex assembly visualization
• Babylon.js: Built-in physics may help with assembly visualization
• PlayCanvas: Good physics support for assembly visualization
• Unity: Excellent physics and collision detection, but with WebGL overhead

Emerging tech: WebGPU Considerations

All frameworks are preparing for WebGPU, which will eventually replace WebGL for high-performance 3D:

• Babylon.js has been a pioneer in WebGPU support, with features like WebGPU snapshot rendering that can significantly reduce CPU usage
• Three.js has an experimental WebGPU renderer
• PlayCanvas and Unity will likely adapt as WebGPU becomes more widespread

For forward-looking manufacturing configurators meant to last several years, WebGPU support should be a consideration.

Performance Benchmarking for Framework Selection

When evaluating frameworks for your specific manufacturing configurator, consider benchmarking:

1. Initial load time for your typical product models
2. Time-to-first-pixel (how quickly something appears)
3. Frame rate during interaction with complex assemblies
4. Memory usage when multiple variants are loaded
5. Performance on target devices (especially sales tablets)

Developer Ecosystem and Community Support

The strength of the ecosystem significantly impacts development speed and long-term maintainability.

Three.js Ecosystem

Three.js has the largest and most mature ecosystem:

• Countless tutorials, examples, and community resources
• Active forum with participation from core contributors
• Extensive add-on libraries like three-stdlib, @react-three/drei, and physics integrations
• Monthly release cycle with regular feature additions and bug fixes

Babylon.js Ecosystem

Babylon.js has a smaller but highly supportive community:

• Direct access to core developers (many from Microsoft) on the official forum
• Exceptional support with bug fixes often implemented within days source: spotvirtual.com
• Comprehensive documentation and Playground examples
• Fewer third-party resources compared to Three.js

PlayCanvas Ecosystem

PlayCanvas has a specialized community focused on the editor and collaboration features:

• Active forums with core team participation
• Documentation covering both engine API and editor usage
• Smaller overall community compared to Three.js or Babylon.js

Unity Ecosystem

Unity’s ecosystem is enormous, but less focused on WebGL specifically:

• Huge community and extensive documentation
• Asset Store with thousands of plugins and resources
• Limited WebGL-specific resources and examples compared to the overall ecosystem
