A new version of EulumdatTools 0.9.7.v20111220 available
A new version of EulumdatTools 0.9.7.v20111220 was published on December 20th at http://www.fold1.com/eulumdattools/.
We again improved the batch conversion of IES files to EULUMDAT by fixing a nasty bug in the File/Import routine.
This improved parser and conversion utility is also available free of charge at ies2eulumdat.appspot.com.

A new version of EulumdatTools 0.9.6.v20111129 available
A new version of EulumdatTools 0.9.6.v20111029 was published on October 29th at http://www.fold1.com/eulumdattools/.
We again improved the conversion of Type B photometry IES files to EULUMDAT to the existing conversion of Type C files.
We also hardened the parser so more files with errors can be opened and displayed, so they can be corrected.
We extended the hardcoded expiry date of this release to well in 2012.
This improved parser and conversion utility is also available free of charge at ies2eulumdat.appspot.com.
Installation

New version of EulumdatTools 0.9.4.v20110729 available
A new version of EulumdatTools 0.9.4.v20110729 was published today at http://www.fold1.com/eulumdattools/.
We added the conversion of Type B photometry IES files to EULUMDAT to the existing conversion of Type C files.
We also hardened the parser so more files with errors can be opened and displayed, so they can be corrected.
We extended the hardcoded expiry date of this release to well in 2012.
Some background theory
The photometric intensity distribution in EULUMDAT files is similar to that a Type C IES file. The center of beam is straight down (or up) and there are vertical (IES: lateral) planes rotating around this central down axis. In each vertical (IES: lateral) plane there are a number of vertical angles. For more info see AGI32 website.Trigonometric conversions
To determine the intensity at a pair of the C and γ angles, we need to interpolate at a corresponding pair of B and β angles. The corresponding B and β angles can be found using these formulas:tan B = cos C * tan γ
sin β = sin C * sin γWe added some extra logic to handle the determination of the right quadrant.
Interpolation used
Interpolation is done using standard lagrange over 3 planes and then over the 3 resulting points.More info

New version of IES to EULUMDAT to IES converter
A new version of the free online IES to EULUMDAT Converter was published today at http://ies2eulumdat.appspot.com/.
There was a nasty bug in the HTML/javascript preventing conversions to take place.
Up on the list of to do items is handling Type B and Type C photometry. Please provide feedback with the poll on the right hand side.

New version of Ies2Eulumdat Converter (again)
A new version of the free online IES to EULUMDAT Converter was published today at http://ies2eulumdat.appspot.com/.
After a discussion on LinkedIn lighting simulation group, I improved the character set recognition, so even if you do not use the "official" ASCII only encoding, your IES and EULUMDAT will still be converted correctly
The parser was improved to handle more case with funny whitespace characters, empty lines and other clutter that does not really follow the standard. Also IES files with versions before IESNA91 can be handled more or less. Instead of giving an error on incorrect format, the parser will now use the oldest format and try anyway. Not all fields will be filled in.

EulumdatTools 0.9.0.v20110121 released: convert EULUMDAT to IES
After extensive testing on http://ies2eulumdat.appspot.com/ the conversion of EULUMDAT files to IES files is now also added to EulumdatTools, the Eclipse based workbench for photometric files.
Select a project or folder with EULUMDAT files in the workspace (files you have previously imported) and choose File/Export. You can further select the files individually.
After selcting the desitination container in the workspace, youy can press finish.
Feedback on conversion progress is shown while the conversion takes place.
People who purchase before the relase dat will be able to use the new release with their existing license.
How it works
Official Release 1.0.0 planned
These are the last feature that will make it into the planned release of version 1.0.0.People who purchase before the relase dat will be able to use the new release with their existing license.
