A Review of Techniques for Total Color Appearance Capture of Material Surfaces
In the domains of computer graphics,the expression of total color appearance of material surfaces,especially the expression of material texture information,is recognized as essential for realizing the three-dimensional digitalization of real objects.Function models and measurement techniques for capturing the total color appearance of material surfaces were examined in this paper.A comprehensive review was conducted on the evolution of material surface reflection characteristics,with a focus placed on the detailed analysis of the unique attributes associated with the Bidirectional Reflectance Distribution Function (BRDF),Spatially-Varying BRDF (SVBRDF),and Bidirectional Texture Function (BTF) models.The development of technologies for measuring the total color appearance of material surfaces was also consolidated and retraced.Advancements were classified and summarized based on the differing mechanical designs of appearance capture devices,which were primarily categorized into robotic arm-based systems,prism-based systems,and camera array systems.The current trajectory of total color appearance acquisition techniques was encapsulated,and insights into future trends in this domain were ventured.Through these efforts,it aims to provide a roadmap and foresight for sustained advancements in the field.
