vulkage

This project was setup by following the mesh shading implementation streaming via Arseny Kapoukine

Now mostly follow the bgfx style with my own rough understanding to do the abstraction.

It is a playground to understand modern graphics programming better.

Depends

• volk
• meshoptimizer
• tracy
• glfw
• imgui
• bx
• bimg
• bgfx_common
• glm
• premake5

niagara part(The streaming by Arseny Kapoukine):

Supports:

• mesh-shading
• task-submission
• Lod
• mesh level occlusion
• mesh-let level occlusion
• frustum culling
• back-face culling

vulkage part:

leash the vulkan in cage

• frame graph

  • sort and clip unnecessary passes and resources based on the contribution to the final result.
  • auto barrier: intend to record the resource state and transform states and layouts atomically.
  • auto alias: alias transition buffers if their lifetime is not overlapped. (Note: images are not been processed yet because a more specific condition required)

• gfx api abstraction

  • vulkan

• profiling

  • based on Tracy

Build and Run:

1. download premake5 and install it first.

2. clone the repo via:

   git clone https://github.com/teassy000/vulkage.git

3. enter the root directory by:

   cd vulkage

4. update sub-modules via :

   git submodule update --init --recursive

5. generate project with command:

   premake5 vs2022 x64

   you can find the solution file in ./build/vulkage.sln

Note: The project tested with vs2022 and worked on Nvidia 3070+ serials card. And it used the vulkan extension: VK_EXT_mesh_shader, default vertex pipeline might not work due to no testing for it.
