Iris

This is a simple OpenGL application whose main purpose is learning Graphics in general and more modern C++. A TODO list will be added and updated as I progress through this journey.

You should be able to compile & run this under most Windows or Linux machines with the following requirements:

• OpenGL>=4.6;
• clang>=9;
• gcc>=8;

The keybindings are as follows:

• ESC: Exits the application;
• F1: Recaptures the frustum;
• F2: Shows Shadow Map debug;
• W,A,S,D: FPS camera movement;
• Shift: Lowers the camera's y;
• Space: Raises the camera's y;
• F: Displays the AABB boxes of the objects;
• G: Toggles between PSSM and PSSM + SDSM;
• C: Toggles frustum culling freeze;
• Right Mouse Button: Enables the camera to be moved around;
• Left Mouse Button: Pick objects in 3D space;

Building

To build this project you will need CMake and a C++ compiler. Futhermore you will need to install Python and pip to install dependencies (jinja2).

Compiling the project requires the following commands:

• git clone --recursive [This Repo]
• cd [This Repo]
• mkdir build && cd build
• pip install jinja2
• cmake .. -G [Your Favourite Generator]
• cmake --build . --target [target] -j[threads]

Where [target] is any of:

• MousePicking
• Framebuffers
• Buffers
• AdvancedLighting
• BasicRaytracing

Assets

To actually run the targets present in this you will need assets, reference the models folder.
