Latest Patents

Bitterli's latest patents encompass groundbreaking methods in light transport and image filtering. The first, titled **"Informed choices in primary sample space for light transport simulation,"** introduces systems and techniques for rendering three-dimensional virtual environments through reversible jumps. This patent describes how mappings from random numbers to light paths can be modeled as an explicit iterative random walk. By leveraging inverses of path construction techniques, Bitterli's invention enhances the Multiplexed Metropolis Light Transport (MMLT) technique, allowing for path-invariant perturbations that preserve the geometry of light paths while generating new samples.

The second patent, **"Robust regression method for image-space denoising,"** presents a novel approach for filtering rendered images. This method utilizes feature buffers that capture key image information, such as surface positions and depths. By performing first-order regression in pixel neighborhoods, the denoising application effectively refines pixel colors, thus enhancing image quality. Collaborative filtering further improves outcomes by averaging results from overlapping neighborhoods.
