3D Product Configurator
Overview
3D product configurators let customers explore products from every angle, swap colors and materials in real time, and interact with feature callouts — all in the browser with no plugins. This showcase demonstrates the core patterns: OrbitControls for navigation, PBR materials for realism, and 3D-to-screen projection for hotspot labels.
Technical Approach
Real-Time Material Updates
The product uses a MeshStandardMaterial with physically-based rendering (PBR). Color, roughness, and metalness are controlled by Alpine.js state and update the Three.js material uniforms in real time — no scene rebuild needed.
Hotspot Projection
Feature hotspots are 3D meshes positioned in the scene. Each frame, their world-space positions are projected to screen coordinates via the camera's projection matrix. HTML labels are positioned at the projected coordinates, creating a hybrid 3D + DOM annotation system.
Environment Mapping
A procedural gradient environment map gives the metallic material realistic reflections without loading any HDR textures. The PMREM generator pre-filters the environment for correct roughness-based reflection blur.
Real-World Applications
E-Commerce Custom Products
Nike, Tesla, and furniture brands let customers configure products in 3D before buying. Color, material, and feature options update the model in real time, reducing returns by 40%.
Automotive Configurators
Car manufacturers use 3D configurators for trim, color, wheel, and interior selection. Buyers spend 10x longer on configurator pages than static galleries.
Jewelry & Luxury Goods
High-value items benefit from 360° rotation and material preview. Customers who interact with 3D product views convert at 2-3x the rate of those who don't.
Industrial & B2B Products
Complex machinery, server racks, and modular systems use 3D configurators to let buyers assemble custom configurations and see exact specifications before quoting.
