Palaeontologist: Dinosaur Footprints – Biomechanics – Simulation
I was contacted just before Christmas by Alan Broun from Beholder Vision, asking me to give it a twirl and write about my thoughts. Beholder Vision, https://beholder.vision/, s a cloud-based photogrammetry solution. That means everything runs in the cloud, rather than on your local hardware. I tend to avoid the cloud-based solutions, because I live... Continue Reading →
One year ago, on Christmas eve 2020, I posted about the Surface Pro X. I was very happy with it, except for one thing - the size. I ended up replacing the Pro X with the Surface Go 2 just a month or so later. My reasoning was that it was about as powerful as... Continue Reading →
Much as the popular view is that palaeontologists spend their days out in the dusty desert digging up fossils, the fact is most of us spend more time at a computer than anything else, and that goes doubly so when your research revolves around computer simulations. As such, a keyboard is probably one of the... Continue Reading →
Yeah, 'Academic' here is more of a stretch than usual... Having been locked down/working from home for however long it's been (12 months? 18 months? a billion years?], and having been using the same computer, tablet, and phone during this time, I've been getting antsy for a new device, particularly one that either fills a...

Using "color match" in photoshop to make two photogrammetric models made under different lighting conditions, more consistent.
A little while ago I wrote about COLMAP-CL, a fork of the original project re-written so as to remove the reliance on CUDA, and therefore Nvidia GPUs. Now, from the same source, OpenPhotogrammetry on Github, comes Meshroom-CL. It's still in pre-release, at version 0.7, but I gave it a run through on my work iMac... Continue Reading →
This is an update of a previous post, because updates to meshroom broke the previous scripts. There's two main changes to Meshroom that have occured: Instead of Meshroom_photogrammetry.exe, you now call meshroom_batch.exeYour scene must have a publish node after the final node. Here's the updated script, and it should be commented appropriately: :: meshroomCMD.bat ::... Continue Reading →
I've previously detailed my process for removing backgrounds from non-ideal photogrammetry data sets, using Photoshop and it's pretty neat object selection tool. The result of removing backgrounds from images is that you can use the 'void' method, without needing a full photoshooting studio. For instance, I have a lightbox, but it's only good for small...

ContextCapture is Photogrammetry software from Bentley. In fact, it is a pretty comprehensive set of tools for photogrammetry, laser scans, meshing, GIS, etc. I was contacted by someone from Bentley, who asked me if I'd like to give it a test run. I was set up with a trial, but aside from that I've not... Continue Reading →
I scan a lot of 2.5D things. That is to say, 3D, but only a surface. Think dinosaur tracks, like this: One of the problems you can come across is if you want to 3D print something like this, it needs thickness. Visualization can also be helped if there’s context for the edges. I’ll outline... Continue Reading →
