Real-time rendering of high-quality effects using multi-frame sampling

Abstract

In a rendering environment of comparatively sparse interaction, e.g., digital production tools, image synthesis and its quality do not have to be constrained to single frames. This work analyzes strategies for highly economically rendering of state-of-the-art rendering effects using progressive multi-frame sampling in real-time. By distributing and accumulating samples of sampling-based rendering techniques (e.g., anti-aliasing, order-independent transparency, physically-based depth-of-field and shadowing, ambient occlusion, reflections) over multiple frames, images of very high quality can be synthesized with unequaled resource-efficiency.
