I have a new alpha version of ies2rad containing bug fixes and enhancements. I am looking for people who would like to try it out.
It fixes the following problems:
- Generates correct Radiance geometry for spheres in 1995, 2002, and 2019 IES files.
- Generates correct Radiance geometry for vertical cylinders that are taller than they are wide.
- Ignores the file source (“File Generation Type”) field in the 2019 version of the file, which would otherwise be incorrectly used as an output multiplier.
It offers the following enhancements:
- Shape information is included in the .rad file comments.
- 1995, 2002, and 2019-version luminous opening geometry is accounted for.
- The 2002 and 2019 IES file versions are recognized and processed appropriately.
- I have made an attempt to do something intelligent with less common “luminous opening” shapes in the 1995, 2002, and 2019 versions of the standard, though I have not implemented any support for new geometry; approximations are substituted and warning messages issued.
