This study introduces an approximation for rendering one bounce glossy interreflection in real time. The solution is based on the most representative point (MRP) and extends to a sampling disk near the MRP. Our algorithm represents geometry as rectangle proxies and specular reflections using a spherical Gaussian. The reflected radiance from the disk was efficiently approximated by selecting a representative attenuation axis in the sampling disk. We provide an efficient approximation of the glossy interreflection and can efficiently perform the approximation at runtime. Our method uses forward rendering (without using GBuffer), which is more suitable for platforms that favor forward rendering, such as mobile applications and virtual reality.
