To reduce the calculation time of synthesizing mesh-based computer-generated hologram (CGH), we define valid frequency domain in off-axis condition which makes different path of DC and three-dimensional (3D) object. Also, we propose a graphics processing unit (GPU) based fast Fourier transform (FFT) method for calculating angular spectrum of mesh-based CGH.
