[BTF Capture and Representation]

Innovative Capture and Representation of the Bidirectional Texture Function (BTF)

Introduction

This project originates in a commercial collaboration between UCL and Change of Paradigm Ltd., with the initial scope of developing an automated facility to capture, model and transmit a compact representation for photo-realistic appearance of delicate fabrics. The publications below reflect academic outputs and follow-up projects of the work.
