Folks I am confused. Please help clarify what is the difference between the ‘Sunlight hour analysis’ done via LB vs ‘Shadow range study’ done using HB/ Radiance.
On Hydra I found a ‘Sunlight hour analysis’ script which uses a LB component. (see screen capture 1 below). This gave me a wonderful butterfly diagram so I can explain how many hours of sunlight the street or plaza etc will get. (see screen capture 2 below)
Next on Hydra I found the ‘Shadow range study’ which uses HB (see screen capture 3 below). I saw a you tube video where Mostapha showed how to run this script (see screen capture 4 below). I was able to run the script and get a HDR image.
My question is what is the difference between these two? Can I extract any sunlight/ shadow values from the HB HDR image or is this just a pretty looking visual? I mean how is this informing my design? What should I learn from it.
