A tree creeper working up the trunk. I selected this part for the vigorous head shake at ~30.0. Different lens this time: Samyang 135mm f2.0 - rather short, no autofocus, no stabilization (but IBIS). Filmed at 1080p 240fps / 8x highspeed mode. No audio.
This talk covers some of my explorative attempts to approximate the density distribution of biological samples from micro-CT data. It was a practice talk but closely resembling the real thing.

Compilation of three videos of northern wren, in bad lighting conditions. Mostly boring, far away, or hidden by leaves, plus there is no audio, yet there are one or two magic moments in here!
Filmed at 1080p 240fps / 8x highspeed mode.
My first real XROMM video.
... or, almost.
The oscillating bone was filmed with biplanar xray videos, its position digitized, and the mesh (from CT scan) then superimposed to match the digitized positions.
Theoretically, the position of the bone (a piglet femur) should match the landmarks, because those were used to find its position.
The offset is parallel, and I suspect that it was introduced by the mesh export which I will have to figure out.
Also, this is actually my first working blender data project, so please excuse the playful beginner's aesthetics (glowing landmarks! Shadows!).
Yet to me, this is an exciting proof of concept, and certainly the entry to a lot of work in blender.
Software used:
ORS dragonfly
blender
custom python code
This is the result of my attempts to port the XROMM workflow to an independent software environment (python, blender).

The daily dose of local European slowmo bird action. Or, in the case of the green woodpecker, less action (the spotted one spotted me) but not less beauty.
Filmed at 1080p 240fps / 8x highspeed mode. No audio.

I was lucky to come across a Pheasant, some of which we know live in the area. It crossed a street with some difficulty, then ran off into a sportsground, where I followed.
Recorded 1080p at 240fps (8x), no audio, manual focus.
