Creating a Dispersion Shader in Cycles (CGC Weekly #17)

It's easy to add a glass shader to anything in Cycles, but it's more challenging to make it disperse light like a real-world prism. In this video, we'll explore the physics behind dispersion, and how we can utilize this info to create a realistic dispersion shader.


  1. thank you for the tutotial.
    i didn't tried yet, but how to tell the shader the difference between white and white?
    real white with the all the wavelengths between red and blue
    and synthetic white with only red, gree, blue wavelength components?

    on a light separating prism, will shader produce three sharp distinct colors or a real rainbow'ish color transition?

    as i saied, i didn't tried yet - i am away from blender at the moment. :(
