The Projections project leverages the Blender Cycles renderer to output high resolution
Each print starts life as an image, the image is turned into a feature set (via SURF and
manual selection) and this is exported as .OBJ and .MAT files (with the colours being pulled
from the original image under the Voronoi region centroid).
Whilst exporting, the Z coordinate of each polygon point is scaled using a mapping from the RGB
colour space, this forms the start of the depth map.
The files are then imported into Blender and the poly are translated or extruded along the Z axis manually until
a suitable final structure is found. Various different light sources are positioned in and around
the structure and finally it is rendered. Shadows are kept in most cases to give the structure
an architectural feel and are removed in other cases when it causes to much of a noisy image.
Each A0 render takes about 12 hours using dual GTX 970s.
