Photogrammetry + Books!

My book for #3DScanBooks on Sketchfab is “The Buildings of England, Cornwall” by Peter Beacham and Nikolaus Pevsner.

This model was created using Autodesk Remake with 100 photos. I also tried Agisoft Photoscan though the mesh came out much simpler in Remake and Agisoft couldn’t pick up all of the black surfaces. The book cover was very shiny and as I had to take the photographs outside, although the lighting was more even, the weather was slightly windy so there was some slight distortion in the model.

The Pilgrim Rabbit, St Mary’s Church, Beverley

The “Pilgrim Rabbit” is one of my favourite medieval carvings and is located at the sacristy entrance within St Mary’s Parish Church, Beverley, East Yorkshire.

The corbel carving, c.1330, is claimed to be the inspiration for Lewis Carroll’s White Rabbit who leads Alice down the hole into Wonderland. But could the Pilgrim Rabbit be a hare? There are also visual similarities with Carroll’s other character The March Hare, otherwise known as Haigha / The Messenger.

In Through the Looking Glass (Carroll, 1871) Haigha is the personal messenger to the White King and is visually alike to the Pilgrim Rabbit in this accompanying illustration by John Tenniel:

From a visit to St Mary’s Church in Beverley, I created a model of the Pilgrim Rabbit (see above Sketchfab model embed) using photogrammetry techniques – quite a change from my usual poly-by-poly modelling in Blender.

To do this I took a series of photographs of the sculpture, around 25, gaining as much coverage as I could from all angles. I then imported these photographs  into Autodesk 123D Catch to create a mesh, and uploaded the obj file along with the texture file to Sketchfab. The model turned out better than I expected, particularly as the area above the rabbit was quite difficult for me to photograph with the sculpture being above head height.
