Lair of the Hoverfly

 Fencepost of the Week #259

 A fearsome predator lurks in the lichens! This striking creature is the larva of a hoverfly. It mostly eats aphids.

Photogrammetry of Very Small Things

 Exciting progress on 'photogrammetry of very small things' this evening: I have devised a simple, but effective rostrum for photographing tiny subjects from every angle. 

 

 Rostrum made from a flower pot, 2 cardboard circles and a wine cork. Lighting from a very small torch fastened to the rig by a rubber band; there is a white sticky label on the light to make the lighting more diffuse.

A shrivelled, dry Cladonia caespiticia specimen. Small... and very frilly. The ruler is cm, not inches.

A really quite detailed 3d model generated from 60 photos taken from various angles. This time I used Apple's free 3d Scanner App which is easy to use and the results seem okay so far. 

Here is one of the 60 source photos used to construct the 3d model:

Here's a link to the resulting 3d model: https://3dviewer.net/#model=https://www.dropbox.com/scl/fi/2o33u6wbjwsqj07to1p32/CladoniaCaespiticiaModel.zip?rlkey=3vmlxhudxoatpm6d366zzw46s&st=bz8nymih&dl=0

 

 ...and a second one: Cetrelia cetraroides. This one was done on a cloudy day with no artifical light sources. 3d view here.

 

 You can also download the model files and use them with your own 3d software here: dropbox. If you have VR, why not try sticking it in there, and blow it up to the size of a house! =o)
