I am a newbie in computer graphics and I am trying to develop a special case of path tracing really slowly! But first: I came up studying the Mitsuba renderer and one of its uses in the so-called GDPT (Gradient Domain Path Tracer). I am trying to build a Cornell Box in this framework and my silly problem arises in realizing which kind of material is a "mirror". In simpler words: I want a mirroring sphere in my scene but I don't manage to create it. According to the documentation that you can find here (http://www.mitsuba-renderer.org/releases/current/documentation.pdf) we can have all the different surfaces explained in section 8.2, which are:
- Smooth Diffuse material (diffuse)
- Rough diffuse material (roughdiffuse)
- Smooth dielectric material (dielectric)
- Thin dielectric material (thindielectric)
- Rough dielectric material (roughdielectric)
- Smooth conductor (conductor)
- Rough conductor material (roughconductor)
- Smooth plastic material (plastic)
- Rough plastic material (roughplastic)
- Smooth dielectric coating (coating)
- Rough dielectric coating (roughcoating)
Can you please help me understand what set of parameters will make a mirroring surface material?
Usually for each kind of material there is a reference XML code (which is what I am using to build the scene). Therefore, the main question remains understanding how to build a mirror, but please take those examples in considerations because the parameters in those are the only things I can tune. Thanks in advance!
