Giraffatitan in all its 3D digital glory (was Digitizing entire dinosaurs 2 (digiS 2016))

Quite a while ago I mentioned that for fiscal year 2016 I again received funding from the Berlin digiS program. Whereas 2015 saw Bone Cellar material digitized, the linked post shows one of the the first results of the 2016 … Continue reading

EAVP 2016 at Haarlem’s Teylers Museum (1)

After all the recent photogrammetry posts it is high time to get away from “stuff that somehow has to do with dinosaurs a little bit” and finally write again about dinosaurs themselves. Which is why I now will write about … Continue reading

Photogrammetry tutorial 12: How to preserve strike and dip or cardinal directions in your 3D model

Photogrammetry is a really nice and easy way of surface digitizing specimens in collections, but also useful in the field. Recently, Marie Attard, a colleague working in England, asked me to help with a project that deals with rock surface … Continue reading

Making Mike Taylor gloriously green-eyed

It has become a bit of a tradition that I use this blog to make Mike Taylor of SV-POW! (and much other) fame a tiny bit jealous. By posting photos of the Museum für Naturkunde Berlin dinosaurs, for example a … Continue reading

“Liberation from the Bone Cellar” – a progress report

Here’s a short update on how my digiS 2015 project is coming along. Yes, 2015 is still running, due to a bunch of unforeseen circumstances a huge theropod sticking its ugly skull into my affairs and demanding to be photogrammetrized … Continue reading

a selfie (digiS2016)

I rarely take selfies. Mostly because I hate being photographed, but also because I do not see the need to show everyone in the world everything I do. Here’s one, though, that I just had to take, mostly in order … Continue reading

Digitizing entire dinosaurs 1 (digiS 2016)

Last year I received funding to digitize a lot of big bones of the Tendaguru collection from the Museum für Naturkunde’s Bone Cellar. This year, I was lucky to again secure funding from the digiS programme. This time, it’s for … Continue reading

some more pictures of Tristan the T. rex

When Niels Nielsen, his brother and I sat down to plan the posture for Tristan we faced a few limitation. Obviously, the posture had to be biomechanically possible. We also wanted it plausible, i.e.: we wanted to show the animal … Continue reading

more Juramuseum & the Kulturgutschutzgesetz

The previous post about the Juramuseum was full of fish, although it did end with a few higher vertebrates. All flattened, though. This time, there’ll be more higher verts, and the spineless stuff will be in 3D! Let’s start with … Continue reading
