Automated Architectural 3D Model Generation for Virtual Reality Walk-Through

Research project in the area of Virtual and Augmented Reality.

About this Project

The proposed project addresses the interactive virtual exploration of buildings. Virtual walkthroughs of property are becoming increasingly popular in the real estate sector. However, currently virtual walkthroughs are costly due to the labor intensive manual generation of virtual 3D content and walkthrough design, and thus, not applicable for brokerage of residential properties. A cost reduction to create 3D virtual walkthroughs and interior would change the entire business in residential property. Especially for designed but not yet built properties, it is a key factor in financing to sell objects already in the development state. However, clients usually fail to imagine a virtually designed building using only state-of-the-art static 2D images or non-interactive 3D renderings. This often results in not purchasing the real estate object until the end of the construction process. For that reason, there is an enormous interest, especially of property developers, to be able to present a real estate object in a convincing and realistic manner at the earliest stage possible.

In this project we aim to develop novel methods for automated geometry creation from the floorplan of a building and automatic interior design by furniture and material placement. Moreover, we plan to investigate methods for immersive VR exploration and intuitive interaction. The methods investigated in this project will enable the automated generation of VR walkthroughs from the floorplan of a building with minimal user intervention within only a few minutes. Additionally, the developed methods will enable a reconfiguration of interior design in real-time. The generated virtual walkthrough will feature high-quality rendering, dynamic lighting (for variable daytime simulation), real walking, and advanced interaction to provide immersive and outstanding user experience. This project also addresses open topics in state-of-the-art virtual exploration and interaction with generated 3D environments.

Based on the expected results of the proposed research project, it will be possible to develop a market ready solution by our partner company after the project finishes to provide realistic, user-centered and interactive visualizations of residential real estate objects. With the intended methodological approach, it is possible to tremendously reduce the costs for 3D content creation by using a novel automated 3D extrusion process based on commonly used 2D blue prints. Other application scenarios of our proposed solution are detached and semi-detached houses. Here, our novel technology can replace the very cost-intensive sample houses by providing a virtual house walk through. Furthermore, we expect our technology to be beneficial for architects and development planners.

In addition to the main focus of the proposed research on indoor spaces and interior design, the results of this project will be beneficial for many areas which require automated generation of 3D digital content, including training, education, rehabilitation, architectural visualization, psychological studies, simulation, in the entertainment industry, and other fields.
