Working with photogrammetry, laser scanning, and all the other techniques I dabble with/intimately rely on, I generate a lot of 3D data. For the most part that data is usually very high resolution, and often quite noisy and in need … Continue reading The best free software for editing and cleaning (decimating and retopologizing) meshes and 3D data 
I get a lot of contacts asking what’s wrong with their software, and usually the answer is that the photos don’t have good overlap, or differing backgrounds. Sometimes I get directly asked how to take the photos, and certainly my … Continue reading Small object photogrammetry – how to take photos
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 … Continue reading How to generate a height map with CloudCompare
Here’s the original post, and links to all posts I think I’ve found a new favourite photogrammetry software! Available here: http://people.inf.ethz.ch/jschoenb/colmap/, I actually came across it when I followed back referral to my own site to this thread on Sketchfab, where … Continue reading Photogrammetry Testing 8: COLMAP
Small post announcing the publication of a new paper: Xing, L., M. G. Lockley, H. Klein, P. L. Falkingham, J. Y. U. L. Kim, R. T. Mccrea, J. Zhang, W. S. P. Iv, T. A. O. Wang and Z. Wang … Continue reading New Dinosaur footprints from China + open data
I should probably have made this post sooner, as it’s about my chapter in the Great Dinosaur Track Book Of 2016: “Dinosaur Tracks: The Next Steps”. It’s a volume I was privileged enough to be an editor for, and it … Continue reading The importance of 3D for tracks -or- how big is your footprint really!
Here’s the original post, and links to all posts I have previously outlined my goal of testing multiple photogrammetry solutions on a single dataset, and reporting times and results. I’m using a dataset based on photographs of this Styracosaurus model … Continue reading Photogrammetry Testing 4: OpenMVG and MVE (+TexRecon)
