Stefan Boeykens

Stefan Boeykens is an architect-engineer from Leuven (Belgium). After graduation, he was involved in architectural practice for about 4 years, before returning to the KU Leuven for his PhD in 2007 on the integration of Building Information Modeling (BIM) in the design process. He worked on a variety of research and education projects, ranging from CAD and BIM to metadata for architectural archives and cost simulations. His main research interests are BIM, 3D modeling and visualization, digital historical reconstruction, parametric design, programming, and interoperability between a variety of software tools, with a special focus on openBIM. He is also the author of Unity for Architectural Visualization, Packt Publishing, the first Unity book on this subject. He is also the author of the http://CAD-3D.blogspot.com blog, which discusses CAD, 3D, and BIM, with a particular focus on free and educational software for architects and interoperability. Under the name of stefkeB he is active online on various platforms and networks.

Who this video course is for

This video course is meant for architects, designers, engineers, students, or in a nutshell, anyone interested in developing interactive environments with Unity. A quick brush up on the basics of Unity and you will be ready to go.

In Detail

Translating CAD or BIM models into a real-time application can seem a tiresome ordeal. Luckily, Unity is very accessible for architects with some 3D experience and it makes importing and presenting models a fun task to do. Architectural visualization through Unity will help you analyze designs and make related decisions even before the actual building is built.

Starting from 3D models in common architectural software, we will discuss the workflow to load the models into Unity and even incorporate model changes. The building model will be refined, with better materials and lighting, so it looks attractive to the visitor. With a few basic scripts, we add the necessary interactivity and finally export it into an application you can share.

This video tutorial shows an efficient and easy approach to apply an architectural 3D model into your project for quick and reliable results.

Approach

Packt video courses are designed to cover the breadth of the topic in short, hands-on, task-based videos. Each course is divided into short manageable sections, so you can watch the whole thing or jump to the bit you need. The focus is on practical instructions and screencasts showing you how to get the job done.

This video tutorial takes an illustrative approach, with attention to how and why you need to do things. Each step leads you to the final walkthrough and, what’s more, the concepts can be applied to other architectural software too.
