A set of data samples illustrating the range of data formats and sizes used in the field of Urban Data.

These datasets are the resulting outputs of the cityGMLto3DTiles data pipeline for transforming CityGML datasets from the Metropole of Lyon to 3DTile Tilesets. The results also include the resulting 3DCityDB docker container volume contents used to produce the 3DTiles found in this dataset repository: https://datasets.liris.cnrs.fr/3dtiles-tilesets-metropolis-lyon-version1

Instructions for how to reproduce these datasets manually can be found here : https://github.com/VCityTeam/UD-Reproducibility/tree/master/Computations/3DTiles

This dataset contains the Bidirectional Reflectance Distribution Functions (BRDFs) related to the study presented in the reference below.

Guillaume Lavoué, Nicolas Bonneel, Jean-Philippe Farrugia, Cyril Soler, Perceptual Quality of BRDF Approximations: Dataset and Metrics, Computer Graphics Forum (Eurographics 2021), May 2021. 

The dataset consists in 100 source BRDFs (from the MERL-MIT BRDF database), subject to approximations with different models, producing a total of 2026 BRDFs (including references). The dataset is provided in two formats: the standard MERL binary format and our own TITOPO format.
