Eurographics 2013 Best Paper Award
Congratulations to Ben Spencer and Mark W Jones for winning an award for Best Paper at Eurographics 2013 for their paper 'Photon Parameterisation for Robust Relaxation Constraints' - [Link to paper]
The paper introduces a technique that augments each photon with information about its origin trajectory. Using this, lighting is separable during density estimation queries. Additionally, we spot fine edge detail using PCA allowing us to employ photon relaxation without detrimental effects. This results in high qualify photon maps that reduce variance and can be rendered with very low bandwidth kernels reducing bias.
