System Requirements Document (SRD)

Project Name: Raven-Highway

1. Introduction

The Raven-Highway project is a highly detailed and precise engineering visualization initiative aimed at creating ultra-realistic 3D renders of a highway corridor in the UAE. The project focuses on preserving the exact geometry of the provided 2D key plan, including all alignments, interchanges, rest areas, and the wadi near IC-8. The renders will adhere to UAE standards for lighting and environmental sensitivity, ensuring a realistic and client-ready output.

This document outlines the system requirements for the Raven-Highway project, including functional and non-functional requirements, user personas, visual design elements, and technical constraints.

2. System Overview

The Raven-Highway project involves the reconstruction of a 2D key plan into ultra-realistic 3D renders, with a focus on nighttime visuals. The system will generate high-resolution PNG images of the following:

1. A full corridor night aerial render (IC-1 to IC-8).
2. Close-up night renders of IC-7 and IC-8, including the wadi.

The renders will incorporate UAE-standard lighting, realistic materials, and precise geometry to ensure accuracy and visual appeal. The project will use advanced rendering tools and techniques to achieve cinematic quality and engineering precision.

3. Functional Requirements

• As a User, I should be able to generate a full corridor NIGHT 3D render of the highway from IC-1 to IC-8, preserving exact geometry and lighting standards.
• As a User, I should be able to generate a close-up NIGHT render of IC-7 with detailed ramps, lighting, and vehicles for scale.
• As a User, I should be able to generate a close-up NIGHT render of IC-8, including the wadi, with contrasting lighting and cinematic effects.
• As a User, I should be able to export all renders in PNG format for client presentation.

4. User Personas

4.1 Engineering Supervisor

• Role: Oversees the accuracy of the geometry and alignment.
• Goals: Ensure the renders match the 2D key plan exactly and adhere to UAE/AASHTO standards.
• Pain Points: Any deviation from the original geometry or lighting standards.

4.2 Visualization Specialist

• Role: Focuses on the visual quality and realism of the renders.
• Goals: Create cinematic-quality images that are client-ready.
• Pain Points: Poor lighting effects, unrealistic materials, or low-resolution outputs.

4.3 Client Representative

• Role: Reviews the final renders for presentation and approval.
• Goals: Ensure the visuals meet the project’s aesthetic and functional requirements.
• Pain Points: Inaccurate geometry, lack of realism, or failure to meet client expectations.

5. Visuals Colors and Theme

Color Palette

The Raven-Highway project will use a unique nighttime color palette to enhance realism and contrast:

• Background: #0A1128 (Deep Midnight Blue)
• Surface (Asphalt): #2B2B2B (Dark Charcoal Gray)
• Text (Lighting Glow): #FFFFFF (Bright White)
• Accent (Vehicle Lights): #FF4500 (Bright Red) and #FFD700 (Warm Yellow)
• Muted Tones (Wadi/Dark Zones): #4A4A4A (Muted Gray) and #1C1C1C (Soft Black)

6. Signature Design Concept

"The Living Highway"

The Raven-Highway homepage will feature an immersive, interactive 3D map of the highway corridor. Users will experience:

• Dynamic Lighting Transitions: As users hover over different interchanges (IC-1 to IC-8), the lighting intensity dynamically adjusts to reflect the specified standards (e.g., brighter at merge zones, softer in the wadi).
• Vehicle Movement Simulation: Realistic vehicle headlights and taillights will move along the highway, leaving light trails that fade over time.
• Cinematic Camera Animations: The camera will smoothly pan and zoom across the corridor, highlighting key features like ramps, bridges, and rest areas.
• Interactive Wadi Zone: Clicking on the wadi near IC-8 will reveal a darker, environmentally sensitive area with soft lighting and natural textures.

This concept will make the Raven-Highway project unforgettable, blending engineering precision with cinematic storytelling.

7. Non-Functional Requirements

• Resolution: All renders must be produced in 4K to 8K resolution.
• File Format: PNG format for all outputs.
• Performance: Rendering time should not exceed 24 hours per scene.
• Accuracy: Geometry must match the 2D key plan with 100% fidelity.
• Lighting Standards: Adhere to UAE lighting guidelines for highways and interchanges.

8. Tech Stack

Frontend

• React for web-based visualization tools.

Backend

• Python with FastAPI for geometry processing and rendering pipeline.

Database

• MySQL for storing project metadata and render configurations.

Rendering Tools

• Blender for 3D modeling and rendering.

AI Tools

• Litellm for LLM routing to assist with lighting and material recommendations.

Orchestration

• Docker and Kubernetes for managing rendering workloads.

9. Assumptions and Constraints

• The 2D key plan is the sole source of truth for geometry.
• All renders must adhere to UAE/AASHTO standards.
• PNG is the only acceptable file format for final outputs.
• Rendering must prioritize accuracy over speed.

10. Glossary

• IC: Interchange, a junction where roads meet or cross.
• Wadi: A valley or dry riverbed that may contain water during rainy seasons.
• UAE Standards: Engineering and lighting guidelines specific to the United Arab Emirates.
• AASHTO Standards: American Association of State Highway and Transportation Officials standards for highway design.
• PNG: Portable Network Graphics, a lossless image format.
