In this paper we present an extended GPU progressive radiosity solver which integrates ideal diffuse as well as specular transmittance and reflection. The solver is capable to handle multiple specular reflections with correct mirror-object-mirror occlusions. The use of graphics hardware allows to consider attenuation of radiation due to reflections and/or transmissions on a per-pixel basis, enabling us to handle multiple specular triangles with different reflection coefficients at once. Alpha masks are used to replace complex geometry in certain cases to reduce computation times. Furthermore, the inclusion of ambient overshooting into the radiosity solver is discussed.
