OK. So here is my updated version. Please do all add in your thoughts. I know I have left out some key points but I would rather they were added by the people concerned - don't be shy! I have simplified the timeline data so it only contains a single date rather than a range. I have also added in an extra item which is an image link. Hembo and I will use this in generating the interactive timeline from these data. Cheers,

This work is part of a long standing collaboration between Szymon Rusinkiewicz and CHI around what has come to be known as Algorithmic Rendering – the use of non -photorealistic rendering (NPR) approaches to make clearer information contained in Red, Green, Blue, Normal (RGBN) data.CHI subsequently employed this approach in a range of cultural heritage contexts. http://gfx.cs.princeton.edu/pubs/Toler-Franklin_2007_IOC/index.php and http://culturalheritageimaging.org/Technologies/Algorithmic_Rendering/ August 2007 http://gfx.cs.princeton.edu/pubs/Toler-Franklin_2007_IOC/pinecone.jpg >> David Potts created a side-by-side PTM viewer proof of concept based on the materialobjects PTM viewer. This allowed viewing in stereo of PTMs captured with a suitable eye separation. He also produced a version of the materialobjects browser that could be embedded in a webpage. Subsequently Hembo Pagi produced a WordPress plugin to wrap up the same code.

Paper compares Polynomial Texture Maps with 6 coefficients against Spherical Harmonics with 9 coefficients and shows that more terms increases the perception of shininess and reduces error. http://users.soe.ucsc.edu/~prabath/prabath_viewlight.pdf September 2009 http://zurich.disneyresearch.com/~owang/pub/images/viewlight.jpg >> Creation of the Leuven minidome. http://www.3d-coform.eu/index.php/tools/minidome and http://www.3d-coform.eu/downloads/3DC_D_4_1_WP4_YR1_FINAL.pdf November 2009 http://www.3d-coform.eu/images/stories/minidome.jpg >> Release of new version of RTIBuilder. This added the ability to use the HSH - Hemispherical Harmonics - algorithm for building RTIs. It also added the ability to reopen an existing "project" and so build the same data set using both algorithms quite easily. There were log file improvements, and other usability improvements as well. http://culturalheritageimaging.org/What_We_Offer/Downloads/Process/ January 2010 >> Blog post by Tom Goskar about Virtual RTI and LiDAR data.

This paper compared the results of PTM, photometric stereo and laser scanning. It concluded that photometric stereo produced the best normals. This is further developed in detail by MacDonald 2011. He also produced a PTM fitter (and phometric stereo fitter) in MatLab that crucially is able to fit arbitrarily large input images by tiling. http://www.isprs.org/proceedings/XXXVIII/part5/papers/152.pdf and http://ewic.bcs.org/upload/pdf/ewic_ev11_s8paper4.pdf June 2010 >> Publication of "Polynomial texture mapping and related imaging technologies for the recording, analysis and presentation of archaeological materials" by Earl, Beale, Martinez and Pagi.

This paper provided an evaluation of PTM across a range of archaeological applications. It demonstrates the value of the Malzbender and Ordentlich 2005 approach to maximum entropy lighting and the potential for batch processing of a PTM archive to identify the best views. We are building on this in our latest work on mining our RTI archive. http://eprints.soton.ac.uk/156253/1/EarlMartinezMalzbender2010.pdf December 2010 http://www.jcms-journal.com/article/viewFile/56/67/558 >> Creation via the AHRC RTISAD project of an annotation framework for RTI data, based on the addition of bookmarks to the RTI Viewer enabling viewer controls to be set according to the parameters saved in an XML bookmarks file. These files could be shared allowing for collaborative annotation. http://acrg.soton.ac.uk/tag/rtisad/ January 2011 >> Martin Hunt described his method for capturing underwater RTI via the RTISAD wiki. He captured a small set of PTMs in freshwater. He also examined a Cornish marine site but at this stage no clear marine PTMs were gathered. He made a fibreglass dome with apertures for placing a light in consistent positions. Data were then processed via a standard LP file. The work was first made public to my knowledge at the AHRC RTISAD workshop in Oxford. http://acrg.soton.ac.uk/blog/1528/ January 2011 >> First multispectral imaging undertaken by CHI.

This paper introduced the RTISAD project and also included the use of RTI data in computer graphic rendering (at Catalhoyuk), microscope capture, RTI annotation and a minidome mounted on and controlled by a commodity camera. It also introduced the use of MentalRay for contour shading, enhancement and non-photorealistic rendering of RGBN data derived from RTI. http://eprints.soton.ac.uk/204531/1/ewic_ev11_s8paper3.pdf July 2011 >> Presentation by Lindsay MacDonald of integration of PTM, photometric stereo and laser scan data to analyse the original and cast of the Hunters Palette, an early Egyptian (c. 3100 BCE) stone slab in the British Museum. http://www.cosch.info/documents/10179/30087/Abstract_WG2_Lindsay+MacDonald.pdf/e21bf8cf-004c-4ce6-86eb-1ad597c6ec6c;jsessionid=52E1F1AB6A31E3E001A9AC7282D8BCC2?version=1.0 March 2012 >> Publication of “Printing Reflectance Functions” by paper with specular micro-geometry by Tom Malzbender, Ramin Samadani, Steven Scher, Adam Crume, Douglas Dunn and James Davis.

May 2012 http://graphics.soe.ucsc.edu/prf/Teaser.jpg >> Hembo Pagi wrote a blog post about a simple way of switching between screenshots from RTI Viewer and original input photographs.

The first attempted capture of PTM that I am aware of took place in 2010 and used a frame with holes cut to provide a means to place lights in a consistent dome orientation. Turbidity proved a significant issue hence the focus of Selmo’s work. Selmo produced the first highlight RTI capture I know of. http://forums.culturalheritageimaging.org/index.php?/topic/230-rti-underwater-a-research-project-university-of-southampton and http://cma.soton.ac.uk/blog/2013/05/underwater-reflectance-transformation-imaging-a-success/ March 2013 http://cma.soton.ac.uk/files/2013/05/Dave-Notes-change-400x300.jpg >> Publication of "Multi-light Imaging for Heritage Applications" by Sarah Duffy.
