CT data to 3D print in 15 minutes using free software
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 →
COLMAP + OpenMVS scripts [Updated]
[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 →
Free photogrammetry software review: 2017
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 →
Maya to Liggghts: Converting complex Euler rotations into Axis-Angle via quaternions.
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...

Automating free photogrammetry: Scripts I use
[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 →

How to generate a height map with CloudCompare
This should give you the basics to generate a heat map of height for a 3D model (in this case a fossil dinosaur footprint), using CloudCompare (One of my top choices of freely available software*). I’m going to assume you have a model correctly scaled, but not necessarily oriented to any specific world axis. The... Continue Reading →
