A new version of EulumdatTools 0.9.8.v20120205 was published on February 5th at http://www.fold1.com/eulumdattools/. We cleaned up the license checking code and removed a potential nasty null pointer exception. This improved parser and conversion utility is also available free of charge at ies2eulumdat.appspot.com.

Installation

For use in Eclipse you can use the standard Eclipse update site

• http://www.fold1.com/eulumdattools/.

For stand alone RCP versions of EulumdatTools choose your platform and perform update after installation.:

• Windows 32 bit OR Windows 64 bit
• Linux GTK 32 bit OR Linux GTK 64 bit
• Mac OSX Cocoa 32 bit OR Mac OSX Cocoa 64 bit

Converting IES files to EULUMDAT: 4500 files in less than 2 minutes!

To demonstrate the speed of large scale batch conversion I created a small demo video for EulumdatTools.

I recently added ready to install downloads for Windows, Linux and Mac OSX both 32 and 64 bit at the download site. 30 day free trial after registration!

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.

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 γ

We 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.

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.
