For a product like adhesive stone, the purchase decision is made visually. The Three.js configurator lets every visitor rotate Adheazy adhesive stones in every direction, observe textures and veins from different angles and under different lighting conditions. The rendering faithfully reproduces the visual behaviour of each material: the natural irregularity of stone, the surface relief and the colour variations depending on light direction.

Three.js is the reference WebGL library for 3D rendering in a browser. It loads 3D models, applies high-resolution textures and manages real-time lighting directly on the client side, without plugins or downloaded applications. For Adheazy, each adhesive stone is modelled with its real physical properties: roughness, reflection and light absorption. The result is a photorealistic render accessible from any modern browser, on desktop and mobile.

For a consumer hesitating between two finishes for a living room, this can be the difference between an uncertain decision and a confident order. For an architect or decorator validating a material choice with a client, it becomes a professional presentation tool integrated directly into the purchasing platform. The 3D view answers the first questions before the customer even contacts sales or orders samples.

Performance optimisation for the configurator was a project in itself. 3D models and textures load progressively so they do not penalise the initial page load. Rendering is optimised to stay smooth on every device, including mobile where graphics resources are more limited.

The choice of a decoupled React and Symfony architecture was deliberate. React handles the entire client-side user interface: navigation, product display, 3D configurator, checkout and customer area. Symfony handles server-side business logic, database operations, B2B pricing rules, payment integrations and communication with carriers.

This separation brings concrete advantages. Perceived performance is significantly better than on a traditional e-commerce site: page transitions are instant, the 3D configurator responds immediately and the checkout never reloads the entire page. On the backend, Symfony provides a solid structure for business code, fine-grained access management between B2C and B2B accounts, and a robust API serving data to the React frontend.

The REST API developed with Symfony exposes product data, pricing, orders and customer information to the React frontend securely. Every call is authenticated, and sensitive data such as negotiated professional pricing is never exposed client-side without checking the user profile.

One of the most complex technical challenges on Adheazy was managing two radically different purchasing logics in a single codebase. The solution relies on automatic customer profile detection at login. A consumer account and a professional account do not see the same site, even though they navigate the same URL.

On the B2C side, the experience is designed for discovery and inspiration. Collections are staged, interior moods are highlighted and the 3D configurator is accessible in a few clicks. The checkout is simplified as much as possible to reduce friction between intent and order.

On the B2B side, efficiency comes first. A professional returning regularly to Adheazy wants fast access to usual products, negotiated pricing without calling sales, and the ability to finalise an order in minutes. The professional area centralises order history, specific pricing conditions and sample management.

Professional pricing management is one of the most complex parts of the project. Each professional customer has pricing conditions defined by purchase volume and commercial relationship with Adheazy. The Symfony backend manages this complexity transparently: professionals see their prices as soon as they log in, without needing to request a quote.

Payment management on Adheazy covers all use cases. Stripe handles card payments, PayPal supports customers who prefer that method, bank transfer covers professionals managing purchases through accounting, and direct debit supports professional customers with recurring orders.

Stripe integration manages the full consumer payment cycle: payment form display, 3D Secure validation, order confirmation and potential refunds. For professionals, SEPA direct debit creates a smoother commercial relationship without administrative friction on every order. Invoices are generated automatically and made available in the professional customer area.

Each payment method is offered at the right moment according to the authenticated customer profile, without weighing down checkout for users who do not need it. A consumer does not see bank transfer options. A professional does not see the PayPal button. Display logic is handled server-side and passed to React through the API.

Adheazy is available in French, English, Spanish and Italian. Each language version was developed with careful attention to the user experience in that language. The 3D configurator, product pages, B2C and B2B checkouts and customer areas work identically across the four languages.

Multilingual management in the React application relies on an integrated internationalisation system. Translations load dynamically according to the selected language, without a page reload. URLs are adapted per language for organic search. Hreflang tags indicate the relationship between language versions of each page to Google, avoiding duplicate-content issues across international markets.
