# Makefile (for gnumake) to translate OBJ files to Radiance octree representing
# an exemplary model of a cellular office (one work desk with small meeting
# desk) as a realistic setting for daylight simulation.
# Modelling and assignment of material names in Blender, export to Wavefront OBJ.
# Furniture is modelled by collections in Blender with marker triangles for
# replmarks, these get material <object>Marker with <object>.obj being the file-
# name of the exported, detailed geometry. The latter are exported with the main
# model but mapped to void by obj2rad.
