I’m trying to create shadows in Grasshopper that can be exported as meshes and that have interacted with 3D geometry, casting onto complex surfaces, not just flat planes.
In older versions of Ladybug, there was a Shadow Study component that did exactly this (video: YouTube demo. I’m currently using Ladybug 1.8.0, and that component is no longer available.
I’ve searched through similar threads, including this one, but unfortunately, the method suggested using Direct Sun with a fine grid doesn’t produce the same result. I’m specifically looking to generate actual shadow geometry, preferably as meshes.
Hi @AbrahamYezioro, I’m working on generating meshed shadows for export as vectors via Make2D. I love this method because it gives me full control over the shadows, treating them as any other geometric object to create unique illustrations. However, as mentioned in this Rhino forum thread, the Shadow component tends to crash when handling more than one or two objects, which is expected since it’s a discontinued legacy component. I’m looking for an alternative solution that can reliably produce meshed shadows.
The issue is the grids. That’s basically doing what the ShadowStudy does but projecting it onto a grid. I don’t want it on a grid. Using the legacy component currently produces cleaner shadow than doing it via the SunlightHoursAnalysis component. I’m looking for the same technique the legacy component used but a method that can handle more than two geometries.
