After studying the composite phase-shifting algorithm for 3D shape compression, two novel methods two-channel phase encoding algorithm and three-channel phase encoding algorithm are proposed. They can improve the compress ratio and the reconstruction quality by storing the 3D shape data into two or three channels of a 24 bit color image. Computer experiments and quantitative analysis provide a guide to achieve appropriate reconstruction quality and compression ratio.
