Focal Engine

Focal Engine is a personal project of a 3D rendering engine, showcasing an array of custom shaders, materials, and rendering techniques.

Features

• Physically-based rendering
• High dynamic range (HDR) rendering internally
• Gamma correction
• Deferred shading
• Screen-Space Ambient Occlusion (SSAO)
• Cascaded soft shadows
• Fast Approximate Anti-Aliasing (FXAA)
• Sky with atmospheric scattering
• Compressed textures support with multi-threaded loading

Terrain

• Chunked terrain with tessellation for LOD
• Frustum culling of sub chunks
• Up to 8 terrain layer materials
• Each layer can define foliage spawn rules

Performance

All instanced entities will have a pass with multiple computer shaders that perform LOD level calculations, Frustum and Occlusion culling entirely on the GPU.

Building the Project for Visual Studio (Windows) as .lib

# Initialize a new Git repository
git init

# Add the remote repository
git remote add origin https://github.com/Azzinoth/FocalEngine

# Pull the contents of the remote repository
git pull origin master

# Initialize and update submodules
git submodule update --init --recursive

# Generate the build files using CMake
# Will work in Windows PowerShell
cmake CMakeLists.txt

Scene Editor

This repository only contains the engine itself to maintain modularity. For the full experience, it is recommended to use the Focal Engine Editor.
