This is a hobby project to build a game engine and eventually a game in my spare time.

Building

This project will likely not build for anyone else at this time.

• SDL3 dll and lib needed
• KTX dll and lib needed
• vcpkg and vcpkg install needed

Assets are not included in the repository and the application will immediately halt without them.

This application is hard coded to run on an Nvidia GPU and Windows 11.

TODO

• config for physical device to use
• bindless resources https://henriquegois.dev/posts/bindless-resources-in-vulkan/
• more bindless https://blog.traverseresearch.nl/bindless-rendering-setup-afeb678d77fc?gi=ff07f56c3097
• descriptor indexing https://chunkstories.xyz/blog/a-note-on-descriptor-indexing/
• resource sync https://themaister.net/blog/2019/08/14/yet-another-blog-explaining-vulkan-synchronization/
• read links in https://github.com/Darianopolis/Links/blob/main/Links.txt
• Do resize and draw in SDL resize callback for maximum responsiveness

Generating Cubemaps with ktx

 ktx create --format R8G8B8A8_SRGB --generate-mipmap --mipmap-filter box --encode uastc --uastc-quality 0  --zstd 5 --cubemap  .\xp.png .\xn.png .\yp.png .\yn.png .\zp.png .\zn.png  skybox.ktx2

Then have to open them up in Nvidia Texture Tools and save them to get the VkFormat correct

I initially relied a lot on this for developing my scene graph.
