This approximation is unbiased and has the characteristic that the error is spread out over large areas in the image.

Sequential Monte Carlo Instant Radiosity

Abstract Instant Radiosity and its derivatives are interactive methods for efficiently estimating global indirect illumination. We focus on the well-known Instant Radiosity algorithm by Keller [], that approximates the indirect light field using virtual point lights Ekller.

From This Paper Figures, tables, and topics from this paper. When combined, the two algorithms form a rendering system that performs favourably against traditional path tracing methods, both in terms of performance and quality. An overhead view of a scene, the light sources, the camera and the virtual point lights VPLs.

Our main contribution is an algorithm for reusing the VPLs and incrementally maintaining their good distribution.

We introduce a novel heuristic sampling method that strives to only move as few of the VPLs between frames kellsr possible. Currently, the limited VPL budget imposed by instnt the algorithm at interactive rates results in images which may noticeably differ from the ground-truth. Although there are plenty methods that focus on solving this problem, most of them are not fast enough for interactive environments. This increases the quality of the individual frames while keeping the noise temporally coherent — and less noticeable — between frames.
