Buddha Statue Photogrammetry for 3D Printing

3D Modeling | Photogrammetry | 3D Printing Prep

The Buddha Statue 3D Model involved creating a 3D model of an historic artefact through photogrammetry and then post-processing the model so it was optimised for 3D printing.

Challenge

Joi Polloi were looking for a way to realistically recreate an artefact and give audiences a way to hold it in their hands without knowing it wasn’t the real thing. We settled on photogrammetry of an object within the Sheffield Museums’ stores. The 3D model would then be processed for 3D printing and painted at a later time.

Solution

Photogrammetry allows for highly realistic digital copies of objects and, for those made of fabrics such as stone, you can get very high quality results. Though 3D printers can now print colours, the colour printing isn’t precise enough to make a perfect colour replica. Therefore, we processed the mesh model and made sure it was fit for the 3D printing process.

Innovation

The process of creating a 3D model from an object using photogrammetry is quite straightforward and therefore quite an affordable option for those seeking ways to create digital or physical replicas that can be viewed by audiences in new ways.

Parlormade Building Photogrammetry

| Photogrammetric processing | Drone SFM

The Parlormade 3D Model is an engaging and creative way to educate and share with visitors the rich history of this shops’ past. The owners of the scone house wanted a way to share the fascinating stories from the building’s history in a way that could be engaged with while sitting inside enjoying a scone and a cup of tea or before customers even stepped foot inside. The photogrammetry model serves as a virtual tour of the building through all three levels and gives a sense of the size of the building when taken apart from its surrounding neighbours in the Shambles area of York.

Challenge

The shop owners wanted a way to showcase the 15th century building, inside and out, while drawing out some of the historical stories - some of which they’ve integrated into the very walls of the tearooms! For instance, there was so much more to be said about some of the infamous ladies of tea, like Queen Victoria, whose portrait hangs over the second floor staircase.

Case Study in SfM + Photogrammetry

 

Solution

It was decided that a photogrammetry 3D model of the interior and exterior would be created over a more conventional 360 tour as this would provide a more immersive and well-rounded experience of the structure virtually. With a 3D model, users could move around inside and see the building from different perspectives, and would not be limited to a path predetermined by the 360 images taken. It was also a way to fully get a sense of the building as it stands apart from the surrounding buildings and understand it as a whole unto itself.

Innovation

To produce a full model of a building like Parlormade, photogrammetry models of each floor were created by taking hundreds of pictures thoroughly capturing each space. Similarly, the exterior needed to be fully captured. For this, drone (or Unmanned Aerial Vehicle (UAV)) Structure from Motion (SfM) 3D modeling was used to reach the high angles required.

Models from both methods were then combined in post processing to create the complete model. This model was then put onto Sketchfab for easy viewing and informational points were added.

CHERISH project Landscape Photogrammetry

| Photogrammetric processing

The RCAHMW CHERISH project sought to provide an interactive way for audiences to better understand some of the historically important landscapes along the coastline in Wales. Having carried out drone photography at four locations, they were then seeking to have photogrammetry models created and processed for uploading on to their page of the 3D model publishing site Sketchfab.

Challenge

Photogrammetry, and especially drone photogrammetry which collects vast amounts of data, creates huge point clouds. We were tasked to take the point clouds the RCAHMW had created, process them into models, and reduce their size so that they could be uploaded on to Sketchfab while keeping them looking high quality.

Innovation

Photogrammetry of landscapes and the resulting 3D models are a relatively new solution to help audiences better understand and visualise an area that otherwise might only be viewed in whole by air.

 
 
 

“It was a pleasure to work with Experience Heritage. Communication throughout the process was just brilliant and the final products were exactly what we were looking for.”

Nostell Priory Dolls’ House 3D Animation

Photogrammetry | 3D Modeling | Digital Animation

The Nostell Priory Dolls’ House 3D Animation involved the Priory’s 18th century dolls’ house which was being restored and placed in its own, new exhibit with in the house. Curators sought a 3D digital animation which would reconstruct the dolls’ house digitally and provide animation which displayed how the house’s doors, which are now separated from the main structure, would have slid open and closed. The digital animation, presented as bookends to a wider video presentation, is now currently displayed as part of the dolls’ house exhibition.

Case Study in Photogrammetry

Challenge

Curators at Nostell Priory wanted a realistic recreation of the historic and fragile dolls’ house in digital form. The intended animation would be a way to exhibit the movement of the object which was no longer available.

Solution

Photogrammetry (or the creation of a 3D model by lacing a series of photographs together) was chosen as the modeling technique because this would provide a much more realistic looking model and picture-perfect textures.

Because of its size and fragile nature, photogrammetry of the front and sides was carried out and the back and top had to be reconstructed with 3D software. Furthermore, because of the intricacies, the interior was represented by placing a 2D image over the front of the model rather than modeling it in 3D.

Innovation

The innovative technique of photogrammetry made it easy and affordable to recreate the artefact digitally and provide a unique storytelling device for Nostell Priory to feature along with the exhibit. Though it’s becoming more popular, as an offering from digital media providers photogrammetry is still quite a niche skill and something even more rare among companies specialising in visualisations for heritage.

Nostell Priory Top Hall 2D image manipulation

Image Manipulation | 3D Modeling | Photogrammetry

The Nostell Priory Top Hall 2D Image Manipulation project involved the creation of a visualisation of the Top Hall showcasing how the space was originally planned with a much more Neo-Classical design. The architect, Robert Adam, was working with owner Rowland Winn on the room when Winn died suddenly and work stopped. Two hundred years later, National Trust curators at the Priory were looking to present the room as it was originally intended with a 2D image displayed on an iPad in the Hall and provided to guests by a room attendant.

The Nostell Priory Top Hall visualisation presents audiences with what might have been had architect Robert Adam’s work continued as intended.

 
 
 

Challenge

The revisualisation of the Top Hall involved replacing the current wood floor with a reflective marble for which the pattern existed within the Priory’s archive. Therefore, the project required the recreation of this floor while realistically reflecting sunlight and colours of objects in the room.

Solution

To recreate a realistic marble floor, a 3D model of the room was created using photogrammetry and the marble floor was created in 3DS Max. By casting light through windows of the room model as well as placing objects in the model as they were in the room, accurate lighting and reflection was achieved.

Innovation

The use and integration of 3D models into heritage visualisation is still quite a new procedure and one in which Experience Heritage specifically specialises. In the Top Hall project, rather than editing a 2D image entirely with Photoshop, the use of 3D model integration added a realism to aspects like the marble floor in sunlight and the Neo-Classical statues with correct shadowing.
