Introduction

What is it all about?
This project was created as a part of doctorate research by Oleksii Doronin. It contains a modelling of the most common types of light field dipslays, including some algorithms to enhance the quality of their visual output without changing the hardware configuration.

What is light field display?
Light field (LF) display is a 3D display which is able to show different picture from different viewing angles, without the need for user to wear a special glasses or enabling position tracking. The most common types of LF displays are lenslet-based (integral imaging, also most of multi-view, and more simple parallax barrier), projector-based (e.g., Holografika), and multiplication-based (e.g., MIT Tensor).

How to use

This project was created and maintained on Windows 10 machine, but potentially can be easily transfered to another platform.

It has the following dependencies:

• OpenCV (tested 4.3) — mandatory.
• LFRayTracerPBRT — mandatory (for now).

You should build the project as follows.

1. Make sure you have OpenCV build, preferably 4.3. If not, download it.
2. Clone this project to some folder on your machine. E.g., in D:/Work/ call git clone https://github.com/LeksiDor/LFDisplay.git.
3. Clone LFRayTracerPBRT to the same folder. E.g., in D:/Work/ call git clone --recursive https://github.com/LeksiDor/LFRayTracerPBRT.git.
4. Build LFRayTracerPBRT. For detailed instructions, go to its project page. Shortly, you should execute a regular CMake build, while choosing build folder as, e.g., D:/Work/LFRayTracerPBRT/build. Don't forget to check PBRT_FLOAT_AS_DOUBLE flag. Then, compile in both Debug and Release.
5. Call Initialize3rdparty.sh script from D:/Work/LFDisplay/ folder. This script will instantiate the 3rdparty folder, which contains all necessary things from LFRayTracerPBRT.
6. Build this project using CMake. Choose build folder as D:/Work/LFDisplay/build.
7. Compile this project. If you have errors, it's not ok.
