Fringe projection profilometry (FPP) plays an important role in the quality control of complex surface workpieces. Simulation using realistic image synthesis referring to physical sensors provide valid measures for the design and optimization of FPP systems. In the simulation of FPP. ray tracing can simulate the fringe image acquisition process. https://www.chiggate.com/igora-vibrance-4-99-medium-brown-violet-extra-sale/
