This thesis describes the simulation of light-object interaction, occlusion, and light wave propagation for the purpose of creating CGHs. Two algorithms that harness the parallel-computing capability of a graphics processing unit for fast CGH generation are presented. The key insight is to divide the CGH computation process into small, independent computation tasks that can be executed concurrently. Different paths for parallelisation are considered, as well as methods of approximation to seek a balance between computational complexity and visual quality. The optical reconstruction of CGHs is analysed to identify the source of reconstruction errors and their impact on the visual quality of the reconstructed images. The study proves that Fourier CGHs can be used to display rich 3-D content with considerable depth and full parallax just like any other types of hologram.
