Hikari

Hikari is my personal Game Engine that I'm writing in my free time.

Vision

To write a easy to use, modular and performant Game Engine in Rust, and also learn more about writing Game Engines in the process.

Features

• Physically Based Rendering
• Image Based Lighting
• Sample Distribution Shadow Mapping
• Multithreaded Asset Loader
• Shader Hot Reloading
• Powerful Render Graph API powered by Vulkan
• Compute Shader support
• ECS Architecture
• WYSIWYG Editor for loading and editing Scenes (imgui)

Current Goals

• Editor and QoL Improvements
• Add scripting functionality (Lua)
• Animation System
• Bindless Render Resources
• Global Illumination (DDGI)

Build

To build Hikari, you'll need to have Rust installed, along with the VulkanSDK.

To build everything in the workspace, run:

cargo build --all

Project Structure

Hikari is divided into a number of smaller crates found inside inside the crates folder. All of the functionality in these crates is reexported by the main hikari crate.

There are also two additional crates hikari_editor and hikari_cli.

You can run the editor from the project root:

cargo run -p hikari_editor

Note: By default the debug builds are compiled with optimizations

Thanks

Here is a list of projects that I'd like to thank which have heavily inspired the development of Hikari:

• Hazel - Hazel Engine
• Bevy - A refreshingly simple data-driven game engine built in Rust
• kajiya - Experimental real-time global illumination renderer
• Granite
• Godot - Multi-platform 2D and 3D game engine
• egui-gizmo - 3d transformation gizmo built on top of the egui library
