Selected by Sketchfab: The Latest Architecture and News

In most architecture projects, the input of the end user of the space is an important consideration; but what if those users are no longer living? Memorial architecture for the dead is a uniquely emotional type of design and often reveals much about a certain culture or group of people. Especially in the case of ancient tombs, archaeologists can learn about past societies’ customs and beliefs by examining their burial spaces. The personal nature of funerary spaces and monuments conveys a sense of importance and gravity to viewers and visitors, even centuries after the memorials were created.

The list of 3D models that follow, supplied by our friends at Sketchfab, explores memorial spaces and artifacts that span both space and time, representing a variety of cultures and civilizations.

Once again, thanks to our collaboration with Sketchfab, here we have a selection of 9 virtual experiences through churches and chapels from Europe, Africa and the Americas. Each small building has its own special story, either geographical, political or structural—from one building that has experienced its own mini tour of Europe, to another which contains some rather unusual building materials. The diverse sites each seem to hold secrets, all of which can now be explored through 3D scanning technology. The fascinating variation in structural forms is also apparent, showcasing how even humble architecture has the potential to create a rich list of virtual spaces.

For a more immersive experience, all of these models can be viewed on a virtual reality headset such as Google Cardboard.

Traditional 3D models made up of surfaces have for a long time aided us in visualizing buildings and spaces, but they often come at a cost: large models require a lot of storage and processing power, and can become incredibly complex to the point where they are difficult to navigate. As a part of our Selected by Sketchfab series, Sketchfab has their eye on a more efficient, increasingly common method of capturing architectural spaces; namely, point clouds. Point clouds are made up of a set of points located in a three-dimensional coordinate system, that when put together merely give an impression of the surface of an object, or the façade of a building.

The method is fairly simple. The collection of data points is generated by a 3D scanner that rotates while emitting a laser that measures the distance to points on surrounding surfaces. This data can then be converted into a polygonal model that can be rendered like any other 3D model. However, the advantages of keeping the scan in point form are what makes it great; the file sizes are much smaller, and the porosity of the point clouds make it possible to see through walls and surfaces, accessing "hidden" spaces and uncommon views of seemingly familiar surroundings. Read on to find out more about the possibilities and advantages that come with point cloud modelling.

Our friends at Sketchfab have noticed a recurring trend: among the many 3D scans shared on their platform, a significant number are of historical doorways. Often neglected in today’s designs, doors and doorways are essential physical and mental transition points between the interior and the exterior of a building. While Mies van der Rohe’s strive for visual continuity and the use of glass doors has some critical advantages, it is not applicable – or only poorly applicable – to every design case. Fortunately, history shows that visually and spatially differentiating doors and doorways from the rest of a facade can be a resourceful alternative.

With this set of 3D models selected by Sketchfab, viewers can explore historical doorways online and discover the spatial sequences that they can offer. From framed, indented, raised, lowered, protruding and ornamented doors, these models clearly showcase the various design strategies available for you to keep your doorway design options open.

Today, thanks to our partnership with Sketchfab, we take you on a virtual tour of some of the most breathtaking historic fortresses across Europe. The design of castles and fortress complexes are particularly interesting because of their strategic siting and defense mechanisms. As strongholds of territorial claim, fortress complexes are meant to be self-sustaining in times of conflict and contain not only defense fortifications but a suite of supporting structures such as chapels, schools, and housing. This effectively turns fortress complexes into a village within a village. These richly detailed scans hosted on Sketchfab allow us to see in detail the urban planning strategies of different historic periods and places.

Using photogrammetry to capture and model existing buildings is a fantastic way to share cultural treasures with the world, and with VR features cropping up everywhere even enables us to give people virtual tours of a site of cultural significance from thousands of miles away. But beyond that, capturing a model of a building is also a great way to digitally preserve that structure at a given point in time - this technique is even being used by Harvard and Oxford to protect structures placed at risk by the ongoing wars in Syria and Iraq.

In that spirit, our friends over at Sketchfab have compiled a selection of cultural treasures that have been immortalized on their platform. Read on to see all seven models, and don't forget that you can view all of them in virtual reality using Google Cardboard.

When making a 3D model, just as with a physical model, one of the biggest challenges is in effectively conveying the feeling of a design's interior. This is made worse by the fact that historically, 3D modeling and viewing software has treated the design being modeled as primarily an object to be orbited around, rather than as a space to be viewed from within. The introduction of first-person viewing modes has improved this, but these still are hampered by the fact that movement is never as simple or intuitive as simply walking around in real space. All of this can make presenting interior spaces a frustrating experience.

However, there are a variety of techniques you can use to display interiors more effectively. In the second of our Selected by Sketchfab series, our partners at Sketchfab have picked out the best examples of from their platform of models that inventively show off interior spaces.

At ArchDaily, we've said before how sharing 3D models online has the potential to change architecture for the better, allowing viewers to explore a design for themselves rather than being presented only the most flattering views via photographs. At the forefront of this 3D-sharing revolution is Sketchfab, a platform which allows users to upload their model and view it directly in their browser.

In this new series, ArchDaily is joining forces with with Sketchfab, to present the best architectural models featured on their platform, as selected by staff members at Sketchfab. In this first installment, we're taking a look at some of the best scans of historical buildings - and don't forget, all of these models can be viewed in virtual reality for the maximum architectural experience!
