System Requirements
System Requirements Document (SRD)
Project Name: rapid-game
1. Introduction
Welcome to the System Requirements Document (SRD) for rapid-game, a groundbreaking SaaS-based AI 3D Game Engine designed to autonomously generate complete 3D games from user prompts. This document outlines the functional and non-functional requirements, system architecture, and design principles for building the AutoGame AI Engine.
Kapil Kumar, based in India, envisions this project as a revolutionary tool for game development, leveraging cutting-edge AI technologies and modular design principles to create a scalable and production-ready system.
The AutoGame AI Engine will empower users to create fully playable 3D games by simply entering descriptive prompts, making game development accessible to everyone, regardless of technical expertise.
