# BRDF that interpolates between diffuse, glossy and reflective?

Is there a way to obtain a parametrized BRDF that smoothly interpolates between diffuse, glossy and mirror? For example, $$\lambda = 0$$ would be perfectly diffuse, $$\lambda=0.5$$ glossy and $$\lambda = 1$$ a perfect mirror. Linear interpolation seems very wrong here.
