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 picked out Xing et al 2013 because it was the first paper on swimming dinosaur tracks that came to hand, but there are many others. Sometimes the tracks look more like feet than these, but not always. A mechanism for the formation of such tracks … Continue reading Swimming dinosaur tracks in the grass in wales? (No)

I’ve tried something new and made a video tutorial: 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, … Continue reading CT data to 3D print in 15 minutes using free software
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 … Continue reading Introducing my Animals in Motion YouTube playlist
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 things are called from the command line, breaking my previous script. If you want detail on what each bit does, check out the original post here. Updated COLMAP + OpenMVS script (v3.4+): ColmapScript.bat: ::These parameters are specific to computer ::Store current Directory: set currDir=%CD% ::get folder name as variable SET “MYDIR=%~p0” set MYDIR1=%MYDIR:~0,-1% for %%f in (%MYDIR1%) … Continue reading COLMAP + OpenMVS scripts [Updated]
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 … Continue reading Free photogrammetry software review: 2017
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 … Continue reading Maya to Liggghts: Converting complex Euler rotations into Axis-Angle via quaternions.
