SHADOW STUDY Equivalent- How to generate shadow outline surfaces from multiple brep inputs

Hi All,

Is there a technique to create shadow outlines in a faster way as I need to compute it for 1000s of objects.
Function has to be similar to "Shadow study component of Ladybug.

Hi,

Some ladybug expert will help here also. But to get better results related to Ladybug visit here

Hi Porusvakshoor,

you could try it with the native GH-Component “Occlusion” http://grasshopperdocs.com/components/grasshoppermesh/occlusion.html
You will rather get regions as output ( curves ) than meshes.
But I think it should be faster than ladybug.
And I recommend you to mesh your breps once ( much faster ), this would speed up both variants.
