We began the 3D modelling process on the basis of the results of the scan. The data the laser scanner had provided contained millions of points, complicating manipulation in the 3D editing software. We therefore generated a model with a lower density, which was more manageable and retained the original’s geometry.
We used the scan’s reflectance data to generate a black and white image, this being the apse’s “skin” or 3D texture map. Displaying the “skin” in two dimensions gave us the base upon which we drew out and animated the audiovisual project.
