An old recurring modelling ‘problem’ for architectural renderings: there’s a city/landscape/road with terrain, and want to put some street markings on it. Might sound simpler than it is. How would you go about it?
A) Bitmap
Plus: color/texture can be added. Terrrain geometry does not really matter.
Minus: hard to draw or edit, needs to be quite big to avoid pixel artifacts.
B) Vectors/curves, projected on the terrain. The approach I normally take. I have a Grasshopper script for that, but it has it’s quirks.
Plus: precise, editable, can have some thickness.
Minus: intersections with the street can happen, espectially when the street geo is a mesh, and when the lines have no thickness.
The problem could of course be extended to put any 2D vector graphics on any surface geometry.
Thanks for sharing any ideas!
