It's a while since I've posted about new papers, so I'm going to have a series of posts catching up on 2022's papers. First up is Jens Lallensack's cool paper in Interface about using AI and machine learning to distinguish between theropod and ornithopod tracks. For those unfamiliar, ornithopod tracks and theropod tracks are both... Continue Reading →
I’m A Reality Capture Convert.
Since I first started getting into Photogrammetry in a serious way, with my 2012 paper on using Bundler and PMVS, and throughout much of this blog’s life, I’ve been a massive proponent of free and open-source photogrammetry software. For years I used COLMAP, and then Meshroom. The latter was particularly good, offering a full pipeline... Continue Reading →
Neural Radiance Fields (NERF), and Instant-ngp – Future of photogrammetry?
I’ve been testing out instant-ngp recently, it’s an open-source software from Nvidia that generates neural radiance fields. That’s a 3D representation of an object that is fundamentally different from the points or verticies and faces we may be used to. Rather than representing an object through 3D coordinates, connections between them, and colours (i.e. vertices... 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 →
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 →
I really dislike rotation maths!
For the last couple of days and nights, I've been doing my best to try and get my Maya scripts working to convert XROMM animations into input files for LIGGGHTS. I've previously done this for my paper with Stephen Gatesy, 'The Birth of a Dinosaur Track', but that was a) quite a while ago now,... Continue Reading →
Trying all the free Photogrammetry!
In which I tried - and failed - to document pros and cons for about a million different combinations of software.
Installing Bash on Windows 10
The recent update for Windows 10 enabled a feature that I’m sure has gone unnoticed by many: You can now install a native linux terminal in Windows. Who cares? I hear you ask. Well, I’ll be writing up guides on some open source software soon, and using Bash on Windows 10 is waaaaay easier than... Continue Reading →
Getting good supports, printing with Dremel Idea Builder 3D20
**update 21/2/19: Not only has Dremel moved to a waaay better slicing software (based on Cura), but the latest firmware (v1.5, 20180611) has enabled standard *.gcode support for the 3D20 model. Finally...** Last year I got hold of a Dremel Idea Builder 3D printer. It’s been great, and I’ve been able to print a... Continue Reading →
Why Windows 8.1 and Onedrive are awesome (and Windows 10 is RUBBISH)
My extolling the wonders for productivity given by windows 8.1 and Onedrive, and my disappointment with Windows 10
