This course is addressed to bioscience researchers and technicians who routinely work with complex biological structures and need to analyze them in three dimensions, and who digitise their samples for any reason, such as digital preservation or retrospective analysis of a previously scanned sample. You may arrive at this course from a diversity of different backgrounds (laser, photogrammetry, CT, etc.) and use it as a basis to move on to further analyses. The course is designed to enable participants to arrive at a three-dimensional image solution by concentrating on not just one methodology or technology but by considering the range that is available. This range is now quite extensive, including such things as 3D imaging, 3D printing, image processing, image filtering, laser imaging, photogrammetry, computed tomography (CT), and more. Images resulting from one methodology or technology should not be the end of the road but a starting point from which you can gain much more by performing other analyses, applying other methodologies or using different technologies, even with existing data. It is easy to become satisfied by one methodology that you know well, yet there may be much more you can achieve. And there are other advantages. Not only will your final result be more precise and accurate, you also have the potential of finding a more efficient approach than the one originally chosen, even though a multi-solution approach might seem inefficient at the outset. The goal of this course is to explain how you can work with a range of technologies with the aim of obtaining a 3D model from different sources. By the end of the course participants should be able to work in an autonomous way to develop high quality digitalizations of samples with the most commonly used techniques and also be able to edit and manipulate the digital models that are produced.

A series of educational resources on 2D and 3D formats are described in this contribution, both applicable to the teaching of subjects related to biology and geology and for research in these areas. The 3D models were generated by three systems: the use of a 3D scanner, 3D photography and digital video camera, plus 3D SketchUp and 3D MAX programs that produce images and videos in several formats. 3D Scanned Objects come from some collections of the Complutense University of Madrid (UCM), which may not be well known but have great educational value. Three-dimensional models can be seen at the institutional website as in a virtual museum. We have chosen objects in the Museum of Comparative Anatomy of Vertebrates (MACV), Faculty of Biological Sciences and the collection of ceramic crystallographic models Romé Jean Baptiste L'Isle (18th Century), composed of 312 pieces belonging to the Department of Crystallography and Mineralogy at the Faculty of Geological Sciences. On the other h...

The digitization of the Pisa Griffin took place in the preliminary phase of a much larger research project; it was part of the extensive scientific investigations that were planned to build a complete corpus of evidence data on the object. The digitization of the Griffin aimed at producing a very high-resolution and accurate sampling of its shape and of its surface decoration and colour, thus touching the spheres of both the 2D and 3D representation. The Griffin is a remarkable object that imposed a number of constraints in the planning and implementation of its digitization. The constraints were both in the complex shape of the Griffin (since the representation of the overall shape should be paired by an accurate sampling of the very thin decorations carved on the surface of the statue) and the dark and often reflective bronze surface. We describe here the procedure implemented to perform the 3D scanning of the object and to process the raw data produced by the sampling instrument....

A call for bioimaging software usabilityBioimaging software developed in a research setting often is not widely used by the scientific community. We suggest that, to maximize both the public's and researchers' investments, usability should be a more highly valued goal. We describe specific characteristics of usability toward which bioimaging software projects should aim.
