This section describes the technologies that make DomiDo possible. It covers the engineering of the block itself — geometry, the universal interlocking mechanism, material candidates, and manufacturability — together with the 3D and augmented-reality (AR) viewer that brings user-generated designs to life on a phone or in a browser, the assembly companion that turns a kit into a finished build, the payment systems that move money safely across the phased rollout, and the scoring system that ranks designs in the gallery. DomiDo is built by Avvyland Limited (UK) and sells universal blocks and fasteners only; every construction shown on the platform is a user-generated design built from those blocks. The pages below describe the technology that serves that simple physical-product business and the user-generated-content (UGC) platform around it.
- Block design — The engineering side of the block: dimensions, the universal interlocking mechanism, material candidates and trade-offs, structural performance, manufacturability, and design-for-tooling rules.
- 3D and AR — How designs are rendered in the browser and on mobile devices: 3D viewer libraries, assembly visualisation, AR placement, glTF/GLB pipelines, file optimisation, performance budgets, and accessibility.
- Assembly instructions — How a buildable design becomes a step-by-step assembly guide: instruction generation, visual conventions, interactive UX, animated sequences, error recovery, accessibility, and printed-versus-digital formats.
- Payment systems — How Stripe is used across the phases: SetupIntent for no-capture pre-orders, PaymentIntent for kit purchases, Billing for AI design credits, Connect Express for designer payouts, plus tax, refunds, fraud, and reconciliation.
- Product scoring — How designs are scored and ranked for the gallery: signal sources, model structure, freshness handling, anti-gaming protections, and the relationship between scoring and merchandising.
