Free software for CT segmentation (2019)

Continuing a common theme of this blog – free or cheap software for scientific purposes, I thought I’d give a quick run-down of the free software available for segmenting CT data into digital models (e.g. objs/stls). This list is by no means comprehensive, but I’ve tried everything here to a reasonable degree. I’m not planning... Continue Reading →

Changing default values in AliceVision Meshroom

I previously gave you a little script that can run AliceVision MeshRoom from the command line, speeding things up when you have a lot of photos.

Batch Script for running AliceVision MeshRoom from command line

Here's a script to reduce the processing of AliceVision's Meshroom to a single double click. Much as I did for COLMAP, (and here) I've put together a batch file that can just be dropped into a folder of photos and double clicked to run the full Meshroom process and produce a filtered, textured model without...

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 →
