Stephanospermum braidwoodensis sp. nov. has four longitudinally orientated sarcotestal wings, two to each side of the major plane that demonstrate 180° rotational (bilateral) symmetry, while the sclerotesta has three prominent longitudinal commissural ribs and the pollen chamber has three small ribs and triangular nucellar beak, both demonstrating radial (threefold) symmetry. This demonstration of both radial and bilateral symmetries in different tissues emphasises the complexities of inferring systematic affinities of fossil seeds from symmetry alone. We consider S. braidwoodensis to be closely related to the co-occurring S. konopeonus Drinnan et al., and postulate that it was born on a fertile truss similar to that of the latter species. Finally implications of our findings for the utility of these methods in identifying additional species from the Mazon Creek biota are discussed, and the advantages and disadvantages of different methods of nodule preparation are considered. We conclude that additional species are likely to be recognised from the Mazon Creek flora by application of the same methodologies used in this investigation.

as case study to test the SiArch, i.e. the rchitectonical lnformative System studied by the Research Unit of L'Aquila University. Before the earthquake of ApriI 6th 2009, happened
during the research period, the building was surveyed using digitaI photogrammetry techniques by PhotoModeler Scanner
6 software. After the seismic event the church was surveyed
with laser scanner. About architectonical surveying, according
to the used instruments, digitaI photogrammetry techniques
are simpler, faster and more economie, but surfaces built by photogrammetric point clouds are satisfying only for flat façades or with regular curvature, and elements with limited
prominence. Using alI surveying data, was reelised the church s
3D photorealistic model. To build an Architectonical Informative
System, the first step is planning the database, that required
to compose 3D model according to constructive elements. Then the 3D model, textured by Autodesk 3DStudioMax 20 1Oand exported in *.3ds format, is imported in ArcScene
of ESRI ArcView 9.3 software. This procedure gives the
possibility to realize an architectonical informative system with
photorealistic 3D model into GIS environment. Moreover another
testing is about the importation of churciis mesh textured
surface, realized by digitaI photogrammetry techniques,
into ESRI GIS environment.

The project aims to test the use of virtual reality as an instrument of exploitation and multi-platform visualisation for villas and historic gardens. This paper describes the methodology utilised which allows us to create clear models of architectural and vegetation elements that will be contributing towards the final model: a successful compromise between realism and easy visualisation. While the modelling of the architectural components has followed a well defined process, as far as the garden is concerned, the development of the project presented greater problems since the methodology requires an hybrid approach between traditional software for garden design and representation and modelling activities for all the parts of gardens that require mankind intervention such as continuous shape pruning. The historical reconstruction of the house might therefore turn out to be a good basis for providing tourists and visitors with new instruments for learning and understanding, even using experiences in augmented reality, and may also offer planners further means to evaluate projects and support them in the decision-making process.

of Manhattan World (MW) building geometry; i.e., the predominance of three mutually orthogonal directions in the scene. Our approach works in two-steps. First, the input points are classified according to the MW assumption into four local shape types: walls, edges, corners, and edge-corners. The classified points are organized into a connected set of clusters from which a volume description is extracted. The MW assumption allows us to robustly identify the fundamental shape types, describe the volumes within the bounding box, and reconstruct visible and occluded parts of the sampled structure. We show results of our reconstruction that has been applied to several synthetic and real-world 3D point datasets of various densities and from multiple viewpoints. Our method automatically reconstructs 3D building models from up to 10 million points in 10 to 60 seconds.

Visualising a phantom: 3D-reconstruction, architectural survey and modern urbanistic valorisation of Schloss Neugebäude, Vienna

Paper: 15. Workshop 15, "Cultural Heritage and New Technologies", 15.- 17. November 2010, Rathaus Wien; co-authored with Michael Schneyder (Wien); Marcel Tschannerl (Regensburg)

However, by showing the first planning stage of Maximilian II and his architects this model is trying to evoke some kind of a historical phantom actually never to be accomplished. Thus, ample historical research had to close the gaps in the archaeological record, shedding light on fundamental questions of architectural history. By using analogies from 16th century Italy, France and Bohemia, the actually unfinished core of the representative southern façade, an impressing ensemble of columns and vaulted arcades, was tentatively reconstructed and linked to a specific fashion of Late Renaissance architectural design. In the same manner, the original shape and subsequent historical development of the roofing was convincingly explained for the first time. Regarding the large gardens and hunting facilities, compelling new evidence could be gathered in combination with the results of the preceding 3D-modeling, allowing for further complex interpretation of Austrian architecture in the late 16th century.

Roman house from Seleucia Pieria, the port city of Antioch. Numerous fine quality mosaics were lifted when the house was excavated in the 1930s and redistributed to several museums in the United States and one in Turkey. With the aid of modern technology, the house has been reconstructed digitally and its mosaics reinserted. Lighting simulation and sightline analysis have been conducted to recontextualize the mosaics, enabling a greater understanding of the interaction between the natural environment and architectural one and how residents integrated these environments into social settings.

support of artificial landmarks. Furthermore, the illumination of the images had to be corrected. The latter consisted in
the gray level adjustment of the background pixels using a correcting polynomial function, which determined the right
intensity for each pixel in the whole image. Many researchers have worked in the alignment problem, mainly using
techniques to minimize various cost functions. We use the average of gray level differences between corresponding
pixels in every pair of consecutive images. This function is minimized using a genetic algorithm. For the 3D
reconstruction, the system detects contours in the aligned images in an interactive fashion. Thus, the user can select
which structures to reconstruct and visualize.
