Refraction in rhino

Is there a plugin that calculates refraction (direction and colors) within rhino?

can you elaborate a bit about what you are trying to do?

To do a refraction study according to the location of the source and the prime and to know how patterns like this are formed

also see the intensity of the colors on the surfaces

Any rendering plugin does essentially what you’re asking.
Vray or Bella, just to say 2 of them, does this in a very accurate way.
The images you posted here show also the dispersion and diffraction behavior not only refraction.
What’s your goal?

Are you looking for text data to be generated that you can add to a spreadsheet, or just images where you can experiment with the shapes and refractions?

The Mosquito plugin has a refraction component.
