Component object model technology is used to solve problems encountered when using three-dimentional (3D) objects to conduct computer-generated hologram (CGH) fast coding. MATLAB and C/C++ are combined for relevant programming under experimental conditions. The proposed method effectively reduces the time required for holographic encoding of large amounts of 3D object data. The CGHaccelerated computing method based on mixed programming is proven to be highly reliable and practical by testing the 3D data of different data volumes. According to the test results, the proposed method improves the efficiency of holographic encoding. The higher the data volume is, the more significantly the computation speed is improved.
