Fisheye image that highlights only the areas with a potential risk of glare

Hi everyone,

I’m wondering if it’s possible in Honey Bee to generate a fisheye image that highlights only the areas with a potential risk of glare, including the DGP values (as shown in the attached example).

Could anyone help me fixing the script to obtain the desired result?

I can’t attach the HDR image because it’s too large, but any other HDR image should work if linked in the Grasshopper script.
(The image was generated with a reflex camera, following the tutorial on Luminance Maps for Daylighting Studies from High Dynamic Range Photography.)

Thanks in advance!

Hi @tru,

In the sample file from honeybee-grasshopper-radiance you can add text to an image. Use the image from the check_hdr output in HB Glare Postprocess.

Hi @mikkel

Thanks a lot for the tips. I managed to get the text on the fisheye image, but I’m not able to color the area with glare corresponding to different DGP values. Is it possible to do that with Honeybee? (see second picture as referance)

Thanks again for the help


Daylight Glare Probability (DGP) with color

Hi @tru,

The only way to highlight the glare sources with Honeybee is to use image that is produced by “HB Glare Postprocess”. But you will not be able to select specific colors as it will use the colorset defined in evalglare.

Hi @mikkel

Thanks again for the information. Even though it’s not possible to assign a specific color since it’s done randomly, is there a way to get a legend for the cd/m2 value associated with each color?

Thanks Mikkel

Hi @tru,

You can’t do this in Honeybee. If you run evalglare in command-line with the detailed results (-d), you will get results for each glare source; the averaged luminance of the glare source is one of them. You also get the averaged position (x and y) of the glare source so you can tell which glare source it is in the image. It will not produce a legend, but it will give you the averaged luminance of each glare source.

That’s fantastic. Exactly what I needed. Thanks so much @mikkel
