how to convert Euler angle to IPF color code?

[Chang-Yun Song]

Hello 

I am a student who wants to learn more about EBSD.

Thanks to the detailed explanation on the site referenced below, I was able to understand how Euler angles are converted in Euler colors.

http://www.dream3d.io/Filters/OrientationAnalysisFilters/GenerateEulerColors/

[ phi1 / 2Pi * 255,  Phi / Pi * 255,  phi2 / 2Pi * 255  '

Unfortunately, I cannot understand IPF color which is commenly use.

I know I can simply use a filter, but I'd like to know how it's converted.

              Euler angle --> which equation?? --> IPF color(001)

Thank you in advance

Best regards,

Chang-Yun Song

Dear Mike Jackson,

I am working on a research paper involving with Euler angles for EBSD data, and I will like to visualize using IPF data. I have tried loading my data into dream3d so that I can generate IPF colors for it, but I was unsuccessful.

Can you help me find a way to do this?

Kind regards,

Emmanuel Atindama

If your EBSD data is in the form of a .ang file then you can use an example that we have included with DREAM.3D:

Prebuilt Pipelines -> Examples -> Exad IPF Colors and just substitute your data in the first filter. 

If your EBSD data is in the form of a .ctf file then you can use the included pipeline, and again, just adjust the input and output filter to load/save data to your computer.
