Imagination is required to use CityEngine, I’ve said this before and I say it a lot in our 3DPathFinder CityEngine training sessions (shameless plug). The power of the rule file is in it’s ability to be used in other contexts and is often only limited by your imagination. Some of what I think Geodesign is also about this, connecting up other peoples workflows, joining disciplines together to form a coherent team.
Take the humble rule that places a parapet around a roof top and places a satellite dish inside, this is the same rule that I use to make my infamous “procedural sheep”. Get your head around that and the world is yours (in a metaphorical sense).
This leads me to a little rule file I adapted yesterday, my colleague and friend Matthias had created a couple of rule files for a client (Philadelphia University’s Geodesign course). One rule file coloured a surface depending on the steepness of a slope, which clearly when drawing a path or a road can be useful. The other rule file was one that placed arrows facing down a slope in a grid pattern, think about water run-off and this is cool, useful stuff.
