System Requirements Document (SRD)

Project Name: regal-website

1. Introduction

The regal-website project is a professional platform designed to empower individual LEGO enthusiasts to create complex, high-fidelity LEGO mosaic sets from their personal artwork. The platform aims to attract the interest of the LEGO company by enabling users to design collector-grade mosaics that showcase their creativity and technical skill. By providing tools for image processing, 3D visualization, and professional-grade instruction generation, the website bridges the gap between personal creativity and professional LEGO design.

This document outlines the system requirements for the regal-website project, ensuring it meets the needs of its target audience and delivers an exceptional user experience.

2. System Overview

The regal-website platform will serve as a responsive, visually elegant, and intuitive website that guides users through the process of transforming 2D artwork into physical 3D LEGO mosaics. The system will cater to individual LEGO enthusiasts who aim to build complex sets that could potentially attract the interest of the LEGO company.

Key features include:

• Image upload and processing to convert artwork into LEGO-compatible designs.
• A smart brick mapping engine for optimal layout and aesthetic fidelity.
• Interactive 3D mosaic visualization for previewing designs.
• Automatic generation of professional-grade building instructions.
• Export and order options for digital files, parts lists, and custom kits.
• A user dashboard for saving, sharing, and showcasing creations.
• Selective re-run capability to allow users to regenerate specific outputs (e.g., updated instructions, previews, or parts lists).

The platform will focus on accessibility, gamification, and professional-grade output to inspire users to create designs worthy of official LEGO recognition.

3. Functional Requirements

• As a User, I should be able to upload digital artwork in JPEG, PNG, or TIFF formats.
• As a User, I should be able to preview my artwork as a LEGO mosaic in an interactive 3D environment.
• As a User, I should be able to customize the size and color palette of my mosaic.
• As a User, I should be able to generate step-by-step building instructions in a LEGO-style format.
• As a User, I should be able to export digital build files in formats like .io or .ldr.
• As a User, I should be able to generate a purchasable parts list with BrickLink or LEGO Pick-a-Brick API integration.
• As a User, I should be able to order a custom collector’s kit with packaging designed from my uploaded image.
• As a User, I should be able to save, share, and download my creations from a personal dashboard.
• As a User, I should be able to track my progress with gamified elements like “Master Builder Level” indicators.
• As a User, I should be able to submit my designs to LEGO Ideas for potential recognition.
• As a User, I should be able to selectively re-run specific outputs (e.g., regenerate instructions, update 3D previews, or refresh parts lists) without starting the entire process over.

4. User Personas

5. Creative Reference Stories

Based on the project’s focus on professional-grade output and the target audience of enthusiasts aiming for LEGO recognition, the "Architectural Marble" story is the most suitable inspiration.

Visual Direction:

• Mood: Timeless, structured, grounded, and sophisticated.
• Palette: Warm neutrals inspired by marble and natural materials, with a focus on elegance and professionalism.
• Typography: Elegant serif for headings and clean sans-serif for body text, emphasizing clarity and refinement.
• Layout: Medium density with structured vertical hierarchy, ensuring a professional and organized feel.
• Motion: Smooth and slow transitions, with effects like fade-in and gentle rise to maintain a polished aesthetic.

6. Visuals Colors and Theme

A unique color palette has been created for the regal-website project:

• Background: #F4F1EB (soft cream)
• Surface: #E6E0D8 (light sand)
• Text: #3C3B37 (matte dark gray)
• Accent: #B28A5E (mocha brown) and #7A9D5E (sage green)
• Muted Tones: #D5CEC3 (warm beige)

This palette reflects the timeless and sophisticated mood of the project, ensuring a professional and inviting user experience.

7. Signature Design Concept

"The Mosaic Vault"

The homepage of the regal-website will feature an interactive "Mosaic Vault" concept. Upon landing, users will see a grand, architectural vault door slowly opening, revealing a gallery of rotating LEGO mosaic masterpieces. Each mosaic will appear as a framed artwork, with subtle lighting effects highlighting its details.

Key interactions:

• Hover Effects: As users hover over a mosaic, it will animate into a 3D preview, allowing them to rotate and zoom in.
• Dynamic Background: The background will subtly shift between warm marble textures, creating a sense of depth and sophistication.
• Gamification: A “Master Builder Level” progress bar will be displayed prominently, encouraging users to unlock new features and badges.
• Call-to-Action: A glowing button labeled “Start Your Masterpiece” will guide users to upload their artwork and begin the creation process.

This concept combines elegance, interactivity, and inspiration, making the website unforgettable and engaging.

8. Non-Functional Requirements

• The website must be responsive and optimized for desktop and mobile devices.
• The system should process image uploads and generate previews within 5 seconds.
• The platform must comply with copyright laws and provide licensing acknowledgment guidelines.
• The website should support accessibility features, including tooltips and visual previews.
• The selective re-run feature should allow users to regenerate specific outputs without re-uploading their artwork.

9. Tech Stack

• Frontend: React for Web
• Backend: Python with FastAPI
• Database: MySQL with Alembic for migrations
• 3D Rendering: Three.js for interactive previews
• AI Models:
  • GPT 5.2 for user-friendly responses
