Res Gestae Divi Augusti, Ara Pacis, Rome, Italy

3D Model of the Res Gestae Divi Augusti on the wall of the Ara Pacis museum, Rome, Italy. Created from 13 images taken on an iPhone 5s. While the wall is completely flat, the model has a slight curve due to uncorrected lens distortion in the camera.

Res Gestae Divi Augusti (The Deeds of the Divine Augustus) is the funerary inscription of the first Roman emperor, Augustus, giving a first-person record of his life and accomplishments. The Res Gestae is especially significant because it gives an insight into the image Augustus portrayed to the Roman people. Various inscriptions of the Res Gestae have been found scattered across the former Roman Empire. The inscription itself is a monument to the establishment of the Julio-Claudian dynasty that was to follow Augustus. Wikipedia

Star Wars is new official reference scale

Low polygon model of the Temple of Apollo at Delphi with a Stormtrooper and AT-AT for scaleI began this model of the Temple of Apollo at Delphi some while back, but only now have I got around to finishing it. It’s a low polygon model, nothing fancy or intricate, and the dimensions are as best as I can get from the literature. The temple today is about as ruined as anything could be, so everything above ground is pretty much conjecture, although there are rules to Greek architecture and some well-preserved examples, so it’s likely not far off.

The model was made using Autodesk Maya and rendered in 3ds Max. It has a simple ambient occlusion material applied and it would originally have been polychrome, i.e. it would have been pretty gaudy!

The Stormtrooper 1 and AT-AT 2 are there for scale. The Stormtrooper is c. 1.8m and AT-AT is, I don’t know, as big as it is. Who knows? It’s not as if it’s real thing or anything. Anyway, it’s scaled to the height of the Stormtrooper based on an image I found searching on Google. Deal with it.

3D Printing and Archaeobotany

Can archaeobotany benefit from 3D printing technology?

pollen-microscopeTwo things I’ve read recently have led me to ask myself this question. The first was reading that a researcher at Massey University, New Zealand, had created 3D printed models of pollen scaled 2000-3000 times actual size. Dr Katherine Holt noticed that her students struggled to identify pollen types through the two-dimensional imaging of traditional optical microscopes. Having seen 3D models being viewed on a computer screen, she thought that the next obvious step would be to 3D print scaled-up models of pollen and, using a confocal microscope, created 3-dimensional models of pollen from four tree species.

We can replicate it for you wholesale

This is incredible. The video below, from the Fraunhofer Institute for Computer Graphics Research (Fraunhofer IGD), showcases what the latest 3D digitisation technology can achieve. Their CultLab3D modular scanning system can take a cultural artefact and produce a high resolution 3D model in just ten minutes. Amazingly, this system carries out all the post processing, image colour correction and texture creation automatically; all the curator has to do is place the object on the conveyor belt at the start, and remove it at the end.

Through automation, 3D digitisation can now be carried out at scales previously unheard of, bringing with it a reduction in cost. By bringing down the cost of 3D digitisation, Fraunhofer IGD claim to have made it financially viable for institutions to digitise whole collections.

From VisualSFM to MeshLab

VirtualSFM point cloud before cleaning.So you’ve created a dense point cloud with vertex colour in VisualSFM, (or any other software), and now you want to convert this into a textured 3D model. How do you do that? With MeshLab, creating textured meshes from point clouds is a straightforward process. This quick tutorial will show you how.

There are three steps in the workflow:

  1. Edit the high resolution VisualSFM colour point cloud
  2. Create a 3D model from the high resolution point cloud
  3. Transfer the colour attributes from the point cloud to the mesh
