The Wireframe Model
The REDM survey generated over 3500 points which were first put into Excel before being imported into CAD to assign different layers to different groups of data. With 3500 data points untangling the mass of data was very labour intensive and because none of the data had been captured an the same physical plane the profiles of architectural features such as pillars, columns and arches could not be swept or extruded but had to be redrawn and 'traced' onto a single plane in AutoCAD before they could be accurately created in the wireframe.
The wireframe model was constructed using a combination of the REDM data and rectified photographs of the interior. The millimeter accuracy of the spatial data created by the REDM meant that all elements could be cross referenced ensuring that the spatial integrity and accuracy of the model was not compromised, even when working from photographs.
Various elements of the interior were not added at this stage such as the mouldings and angels above the north door in the nave; these would be modelled once the wireframe had been exported into the 3d application to produce the final renders if they were thought necessary.
Once the wireframe was completed it was exported into Autodesk VIZ for the final stage of modelling- adding the textures, lighting and wall paintings.
