The public will have the
first chance to see the stunning 3D visualisations of the Mackintosh Building
created following the fire it was revealed today 6, October 2016. An exhibition featuring
large-scale point cloud images together with photographs of how the work to
create visualisations was undertaken will open in the Reid Building at the GSA
on Friday 7 October 2016.

The images have been created
from a series of digital surveys of the building starting in the immediate
aftermath of the fire. The work was undertaken initially by the Centre for Digital Documentation and Visualisation – the partnership between the GSA and
Historic Environment Scotland behind the acclaimed Scottish Ten.

“The
collective experience of working on a range of highly challenging historic
buildings and heritage sites around the world had allowed us to build unique
expertise in documenting complex structures,” says Head of Data Acquisition Alastair Rawlinson. “This
was of significant benefit for the digital documentation of the Mackintosh in
the difficult circumstances immediately following the fire.”

The 3D visualisations of “the Mack” form the basis of a BIM (Building
Information Model) which will document every stage of the restoration and
create a detailed record of the work undertaken for future use both by the GSA
and other organisations carrying out complex restorations of historic
buildings. Currently the team has scanned from over 500
individual locations within the building as well as capturing high-resolution
HDR photography from each scan position.

“By using this
cutting-edge technology, the architectural beauty of the Mackintosh is seen in
ways never before possible. It allows new visual perspectives to be gained,
while the 3D data is providing tangible, practical benefits for the restoration
process.”

3D laser scanning is a
rapid, non-contact, accurate and objective method for digital documentation of
the built environment and lends itself particularly well to historic buildings,
which are often architecturally complex. The technique can also be used to
record engineering structures, urban streetscapes, archaeological sites and
landscapes.

landscapes.
A laser beam scans the
surface of an object up to 1 million times every second. The returning,
reflected laser light is used to compute the distance to the surface and the
angle of incidence. Up to 1 million spatially accurate xyz coordinates (or
points) are collected every second with current models of laser scanner. This
data is referred to as a 3D point cloud, which defines the surface
geometry of the building or site of interest.

In addition to xyz
coordinates, the 3D point cloud often includes other information, such as
intensity of the return of laser signal and RGB values. Point clouds are
acquired from many locations within a single project and joined together to
produce a 3D dataset with accurate dimensions. The point cloud can be very
useful in itself for conservation analysis and condition monitoring, or it can
be further processed to produce architectural drawings, interactive 3D models
and building management models.
