Interior design is a complex process that involves spatial planning, aesthetic arrangement, and efficient utilization of available resources. Traditional interior design approaches rely on manual sketches, 2D layouts, or expensive professional software tools, which often fail to provide real-time interaction and accurate visualization. These limitations lead to inefficient decision-making, increased costs, and unsatisfactory design outcomes.This paper presents the design and implementation of a Web-Based Virtual Interior Designer, an interactive system that enables users to create, manipulate, and visualize interior spaces in a real-time 3D environment. The system leverages Three.js, a WebGL-based JavaScript library, for rendering high-performance 3D graphics directly within a browser. The backend is developed using Node.js and Express, providing RESTful APIs for data processing and communication. User data and design configurations are stored in MongoDB, ensuring scalability and efficient data retrieval.The system supports advanced interaction features such as object selection using raycasting, translation along multiple axes, rotational transformations, and persistent storage of user designs. Secure authentication is implemented using JSON Web Tokens (JWT) to ensure data integrity and access control. Experimental evaluation demonstrates that the system achieves smooth rendering performance, low latency interaction, and efficient database operations. The proposed solution is scalable, cost-effective, and suitable for applications in interior design, real estate visualization, and architectural planning.
