Some suggestions

[thatname]

Hi, this library is very cool !
After using it, I have some suggestions:

• Make VKResource and MTLResource abstract, move implementation to image/buffer/sampler/accel subclasses. After change:
  • Resource subclasses cost less memory.
  • Most branching logic can be removed, because all methods of Resource are virtual.
• Add build targets for each underlying graphics API, then we can build dynamic libraries.
• Add CopyTextureToBuffer(), which is useful.
• Make debug layer optional. For now, debug layer is always enabled when debugger attached, which is slow.
• Add depth range parameter for SetViewport().
• Remove glm from acceleration structure dependency, user may prefer other math library.
• Required CMake version is too high(3.28), lower to 3.1x?
• Use CMake fetchContent instead of git submodules for external dependencies, which is more flexible.
  I've forked the repo, trying to accomplish all the above. I'll open a pull request if helpful.

Hi! I'm glad you liked it. And thanks for pointing out some issues.

Yes, there are some functions missing and probably not just CopyTextureToBuffer or depth range. As well as some code need a bit refactoring.

Add build targets for each underlying graphics API, then we can build dynamic libraries.

I will add target FlyCube that contains implementation for all graphics backends. Is this what you offer?

Required CMake version is too high(3.28), lower to 3.1x?

3.28 was required to link with MoltenVK.xcframework. I ended up replacing the version with 3.22 in bd18fbd . Is this still too high?

I'll take a look at fetchContent.

I mean one target for one backend. If there is a D3D12 DLL and a Vulkan DLL, An app can choose to load only one on start, thus consume less RAM.

3.22 is OK. For Ubuntu v22.04 LTS, current version of CMake package from offical source is 3.22.1-1.
