So Engine

This is a learning project, for grasping some basic concepts in Vulkan APIs and building a game engine.

Dependencies

• spdlog (submodule)
• glfw3 (submodule)
• glm (submodule)
• ktx (submoudle)
• tinygltf (submodule)
• Vulkan SDK (note: need to be installed locally, so that tools like vkconfig can be utilized)

Architecture Overview

This project adopts an object-oriented, modular architecture. The core idea is to implement different application features by inheriting from a common Application base class:

• Application: Implement some basic logic like Vulkan instance, physical device, logical device and swapchain initialization
• ComputeApp: Inherits from Application and implements compute-focused tasks (such as particle simulation) using Vulkan compute pipelines.
• ModelApp: Inherits from Application and implements model loading, rendering, and texture management.

Each derived class can have its own configuration struct (such as ComputeAppInfo, ModelAppInfo). This design makes it easy to extend the engine with new application types—simply inherit from Application and implement the required interfaces.

I have just decoupled window management procedure from the rendering engine (basically following the same architecture in Vulkan-Samples). Maybe the next improve is to construct a user interface using Dear ImGui?

Functions Implemented

Compute Application

The program runs a simulation of up to millions of paricle collision simulation(works on my laptop).

Model Application

The program can load a gltf model from models directory, while loading ktx2 texures. However, it supports only one texure file for mapping.

Issues

Because I'm working on macos, there might be some compatibility issues building on other platforms.

To do

• Support cubemaps and texture arrays
• Deffered shading
• Ray tracing
