it's really not so complex what's going on, but what could be really interesting - what I'm after - is to 'suggest' different types of inhabitation eg running, walking, climbing, sitting etc by way of geometrical operations informed by the underlying surface curvature. A steep area might get enclosed by a railing, in fact there might be railings at several different threshold lines which would indicate different possible routes. Other than that, maybe if the curvature is almost non-existent the stairs would be'excluded' and open, smooth ramp type space would be made available. But one thing at a time, I suppose. Right now I'm fixated on translating the equivalent shifts in colour from the analysis into geometry - curves on a surface. if you have any ideas, I would be very appreciative. thanks!
