Palaeontologist: Dinosaur Footprints – Biomechanics – Simulation
A couple of weeks ago I was out walking in North Wales near Conwy, and came across this: Intriguing! This was on the top of the hill near Conwy, and there were no animals immediately visible. But it did get my mind thinking about apparent swimming dinosaur tracks I’d seen figured before: I’ve... Continue Reading →

I've tried something new and made a video tutorial: https://www.youtube.com/watch?v=dnwfKBj4WTs However, personally I have little time for video tutorials, so here's a written version: Get your CT data: Fairly obviously, you'll need some CT data. I assume you have your own, but if not, you can download some from John Hutchinson's excellent CrocBase resource -... Continue Reading →
A while back I got a high speed camera from https://www.slomocamco.com/ (I'm planning on doing a write up on the camera at some point). In parallel with a course I've been developing and teaching for the first time this year - Animals in Motion - I've been capturing various videos of animals moving in slow... Continue Reading →
[updated 10/7/18 to use development version of COLMAP, and include environment variables] It's been a while since I wrote anything on the blog - an extremely high teaching load has kept me from tinkering. So to ease myself back in, here are updated scripts for running colmap and openMVS automatically. COLMAP 3.4 changed the way... Continue Reading →
Given how insanely popular my 'trying photogrammetry software' series has been this year, I thought I'd round up what I've tried, what's worked well, and what hasn't. Obviously I gave each piece of software in my blog posts a go with a standard dataset. That photo set was not ideal - it includes photos taken... Continue Reading →
I’ve previously discussed on this blog my love of dealing with a combination of rotation maths and awkward software. I finally solved the problems that have been bugging my simulation workflow for the past 5 years, and I thought now would be a good time to share the mistakes I’ve made, and the code that...

[updated 17/12/17 to get rid of unnecessary meshlab portion] [updated 01/04/18 - Updated scripts for version 3.4+ of COLMAP] In a vain attempt to be useful, I want to share the script I'm currently using to automate my photogrammetry workflow. I'm using COLMAP in conjunction with openMVS on Windows 10 at the moment, and I... Continue Reading →
A somewhat belated blog post about my recent paper with Stephen Gatesy, published in JVP (If you don't have access, just drop me an email). It's one of the papers I'm most proud to have worked on, because I think it's a really interesting discussion about what we mean when we say a track is... Continue Reading →
