As far as I know, reflectance should represent the ratio between the results of reflection and refraction. Why not simply blend them using a formula like
a * refract + (1-a) * reflect? Is there any concept I might have overlooked?Additionally, I hope the article can provide more information on the Fresnel equations. In the current article, this part is just presented as a "magic function", and I would appreciate more educational content on this topic."
