Researchers have developed a novel framework called SMAC for monitoring shape and surface color in 4D point clouds, which represent both geometric and material properties. This registration-free approach utilizes the spectral properties of the Laplace-Beltrami operator to detect deformations and color anomalies without requiring mesh reconstruction. A simulation and a case study on functionally graded materials show SMAC's effectiveness in identifying subtle defects and diagnosing their sources. AI
