knut0815 / Luz

a Vulkan real-time rendering engine focused on PBR and Ray Tracing (Windows and Linux).

Luz Engine

A Vulkan engine that I'm developing to study and implement modern rendering techniques used by AAA games.

Features

• Deferred Rendering
• Real-time ray traced shadows and ambient occlusion
• PBR Shading with metallic, roughness, normal, ambient occlusion and emission
• Vulkan bindless resources
• Scene hierarchy
• Asynchronous glTF and OBJ model loading
• Viewport camera with Perspective and Orthographic projections and Fly and Orbit controls
• Widgets for adjusting Vulkan settings at runtime

Gallery

• Deferred Rendering (Light, Albedo, Normal, Material, Emissive and Depth)

• Ray traced shadows and ambient occlusion

• PBR Shading and glTF models

• Textures drag and drop

Requirements

• A GPU that supports VK_KHR_ray_query extension (list of supported GPUs)
• C++17 compiler. Tested with Visual Studio 2019, Clang and GCC
• CMake 3.7 or higher
• Vulkan SDK

For Linux

This projects uses GLFW library, to compile it under Linux with X11 (like the default Ubuntu 20.04) you will need:

sudo apt-get install xorg-dev

If you are using another window manager (like Wayland) you can check the dependencies here.

Build and Run

git clone --recursive https://github.com/hadryansalles/Luz
cd Luz
mkdir build
cd build
cmake ..

• GCC or Clang:

make run -j

• Visual Studio: open build/Luz.sln and compile/run the project Luz.

• GLFW used to open the application window
• glm used as the math library
• ImGui used to make the user interface
• ImGuizmo used to create 3D gizmos
• spdlog used as the logging library
• stb_image used to load image files
• tiny_obj_loader used to load wavefront .obj files
• optick used to profile the engine
