Radiance colorpict and perforate
For anyone familiar with the Radiance picture.cal and perforate.cal functions, I have a few questions:
- What are the acceptable file types for picture.cal?
- What other commands exist beside -s that can dimension the perforate.cal pattern? Is it possible to set the distance between objects separately from the object size?
- What is the relationship between RGB value in the colorpict and picture.cal commands and the transmissivity? It appears that the RGB value that I set in my image file determines the visible transmittance. I performed a simple box study with windows mapped with solid fills at three different RGB values (black, grey, white) and found a somewhat linear relationship between transmittance and RGB value. I would attach an image file visualizing this study but apparently I need ten points to do that...
Thanks in advance for your help and insight.
EDIT: Now that the diagram is uploaded, the RGB values are black (0,0,0), grey (155,155,155), and white (255,255,255) for the image files used with the colorpict + picture.cal function.
You should have enough points to upload now.
I suggest to post this question to radiance forum: https://discourse.radiance-online.org/
Good point, Mo!
Thanks, Mostapha. I am still awaiting approval from the Radiance discourses site so I am exploring answers elsewhere.
Let me check that for you. I didn't get any notifications to approve new accounts on Radiance discourse.
