IHC Graphics Framework

A Vulkan graphics framework create by I Hsuan "Mark" Chen

Current structure

• Entry Point
• Application
  • SampleApplication (User defined application)
  • Scene (User defined scenes)
  • CustomBehaviors (User self defined logics like scripting)
    • CPUFrustumCulling (specifically for grass at the moment)
    • ImguiContext (UI Helper for debugging)
• Engine
  • Core
    • Time
    • AssetManager
    • SceneManager/ GameObjects/ Components
  • Graphics
    • Graphics Manager
    • Animation (Model loading/ Animator/ Animation/ Inverse Kinematics)
    • Particle
    • Grass
    • Fluid
    • Vulkan (VKWraps/ RenderSystems/ different pipelines & shaders/ compute shaders)
    • Camera
    • Renderer (Swapchain)
    • GraphicsAssetCreator (between assets & Vulkan resource allocation(descriptorsets/ buffers/ image)
  • Imgui (debugging interface)
  • Input
  • Math (Custom quaternion/ VQS/ Path)
  • Window
  • Physics (Softbody/ Spring)

Build Instructions

1. Download assets and extract to corresponding location
   https://drive.google.com/drive/folders/1jxcT7dTBuUUo0AkOVzhjSxDT3kY5J2M6?usp=drive_link

2. Build project in VS22

3rd party libraries

• glfw 3.3.8.bin.WIN64
• glm 0.9.9.8.
• Vulkan 1.3.243.0
• imgui
• stb_image
• Open Asset Import Library (assimp)
• tinyobjloader

Applications
