Abstract
Three-dimensional (3D) visualization technology, such as augmented reality (AR), has served as the display for building information modeling (BIM)-based architectural design collaboration to provide more effective design observation and communication for stakeholders. That said, AR has several technical limitations in terms of personal device issues, user experience, and visualization quality. A new form of AR called spatial augmented reality (SAR) has been introduced to address these issues, which uses a digital projector to present graphics on physical objects for augmenting real-world objects. Therefore, SAR has great benefits and potentials to combine with BIM for design collaboration. This paper introduces a BIM-based SAR operational framework, where 3D building models generated from BIM software are imported to projection mapping tools to display building surface textures on physical white building models. A case study using Revit and 3ds Max as the BIM software, and MadMapper as the projection mapping tool, was conducted to demonstrate the feasibility of the proposed framework and to evaluate the projection performance of SAR. The case study showed that the texture of BIM models could be projected on the objects clearly and realistically. Additionally, the proposed SAR method potentially offers intuitive observation of building models and comfortable wear-free experience for collaborative design, and the qualitative analysis by changing the parameters was conducted to test the different projection conditions. Since it is expected that the use of SAR can be promoted by overcoming the discussed technical limitations and possible solution application, this study aims to traceability provide the whole process of BIM-based SAR for architectural design collaboration.
Highlights
For architectural design, effective design collaboration is vital, as it helps to promote teamwork through encouraging cooperation, as well as sharing stakeholders’ ideas and project knowledge [1].Architects often work with peers and professionals from other relevant backgrounds to address complex problems that are synthesized by multidisciplinary issues
We propose a conceptual framework for building information modeling (BIM)-based projection mapping using spatial augmented reality technologies for better architectural design collaboration through rapid prototyping of BIM-based 3D models
BIM-based augmented reality (AR) design collaboration has been a popular means of presenting design solutions
Summary
Effective design collaboration is vital, as it helps to promote teamwork through encouraging cooperation, as well as sharing stakeholders’ ideas and project knowledge [1]. Effective design collaboration can foster more creative design proposals, which might not be possible with the limited capability of architects [2]. The use of building information modeling (BIM) has facilitated close cooperation between different project stakeholders, including architects, engineers, contractors, Appl. Sci. 2020, 10, 5915 and clients during the design phases of construction projects [3]. The technical core of BIM consists of could further promote the use of visualization as a method to exchange ideas and share knowledge within and amongst various stakeholders in a project, and some BIM viewer software are developed and available for users’ communication [5]
