Detailed Description

Introduction

This module is related methods which generates CGH based on depth map. It is supported single core processing, multi-core processing(with OpenMP) and GPGPU parallel processing(with CUDA).

I. Depth Map Hologram Generation

• Implement the hologram generation method using depth map data.
• Improve the performance of the hologram generation method.
• Implemented on CPU and GPU.
• The original algorithm is modified in the way that can be easily implemented in parallel.

II. Algorithm

• Propagate from the previous depth plane to the current depth plane.
• At the last plane, back propagate to the hologram plane.

III. Modified Algorithm

• Back propagate each depth plane to the hologram plane.
• Accumulate the results of each propagation.
