We introduce a new hardware-accelerated method for constructing Deep G-buffers that is 2x-8x faster than the previous depth peeling method and produces more stable results. We then build several high-performance shading algorithms atop our representation, including dynamic diffuse interreflection, ambient occlusion (AO), and mirror reflection effects. Our construction method s order-independent, guarantees a minimum separation between layers, operates in a (small) bounded memory footprint, and… CONTINUE READING
