Generative Detail Enhancement for Physically Based Materials

no code implementations19 Feb 2025 Saeed Hadadan, Benedikt Bitterli, Tizian Zeltner, Jan Novák, Fabrice Rousselle, Jacob Munkberg, Jon Hasselgren, Bartlomiej Wronski, Matthias Zwicker

The details it generates are then backpropagated from the enhanced images to the material parameters via inverse differentiable rendering.

A Radiance Field Loss for Fast and Simple Emissive Surface Reconstruction

no code implementations27 Jan 2025 Ziyi Zhang, Nicolas Roussel, Thomas Müller, Tizian Zeltner, Merlin Nimier-David, Fabrice Rousselle, Wenzel Jakob

Building on existing emissive volume reconstruction algorithms, we introduce a subtle yet impactful modification of the loss function requiring changes to only a few lines of code: instead of integrating the radiance field along rays and supervising the resulting images, we project the training images into the scene to directly supervise the spatio-directional radiance field.
