The first image is a conventional photograph taken from directly in front of the fossil. I've adjusted the levels in the image to bring out the detail. Note the rather wonderful feather impressions of the wings and the fuzz on the neck.
This is the 3D data generated from the photographs taken for reconstruction using photogrammetry. There were 38 images in all, and these were combined to generate the above mesh. The bones are clearly visible, and the feathers of the left (our right, we're looking at the front of the bird) wing are also visible. The rectilinear features visible on this mesh are possibly artefacts of the alignment of the photos, perhaps due to subtle changes in the way each photo was lit or having the glass in-between the camera and the subject. However, I'd have to check this - oh for the luxury of on-site processing!
Above is an unadjusted render of the final textured mesh. Below is a close-up of the final mesh, with the camera positioned at a jaunty angle which shows off the quality of the model. This is lit with a single omni light with ambient occlusion active.
The quality of the mesh is well displayed in this image, and enables us to examine the fossil from all angles and also by loading the model into a viewer we can take a high-quality 3D model of this fossil anywhere we can take our laptops, iPads or smartphones. This is an effective way of accessing fossils, gathering usable data which is readily available at any time, and creating a record of the specimen which is useful for research.
