[Radiance-general] glass modifier under different angles

[Lars Oliver Grobe]

Hi,

I have one question about the glass modifier.

Transmittance depends on both the materials properties and the distance
that light is traveling through the material. This distance depends on
the angle under which the ray hits the surface, and will be shortest if
hit perpendicular. Is this correctly modeled by the glass modifier,
which does not know the thickness (but the refraction of the material)?
Or do I need a 'solid' glass body to model this, with dielectric?

CU Lars.
