[Radiance-general] Specular and diffuse reflection

[Jiajie Zhu]

Hi everyone,

I have a fundamental question about material types.
Do these material types, 'glass', 'metal', 'plastic' and 'mirror' all
perform both specular reflection and diffuse reflection in the simulation?
Or which type of reflection they can represent?
Could someone give a direct answer and explain in a mathematical ways if
possible.
Many Thanks!

Best Regards,
Jiajie
