An experimental high-level C++ abstraction library for Vulkan with transparent suballocation, resource tracking, and simplified resource creation.
VkHLF is an experimental high-level C++ framework built on top of the Vulkan graphics API. It simplifies Vulkan development by adding features like automatic resource tracking, transparent memory suballocation, and reference counting, while staying close to the native Vulkan API. It addresses common challenges in Vulkan, such as manual resource lifetime management and device memory allocation, making it easier to write robust graphics applications.
Graphics and game developers working with Vulkan who want a higher-level abstraction to reduce boilerplate and avoid common pitfalls, but still need fine-grained control over GPU resources. It's suitable for those building performance-sensitive applications like game engines or real-time rendering systems.
Developers choose VkHLF because it provides a balance between Vulkan's low-level control and higher-level convenience, offering automated resource management and suballocation without completely abstracting away the API. Its design focuses on performance and safety, reducing the risk of GPU resource misuse while maintaining flexibility for advanced optimization.

Implements a ResourceTracker interface to monitor GPU resource usage, preventing accidental deletion or modification of resources still in use, which reduces common Vulkan pitfalls as described in the GPU Resource Tracking section.
Provides a DeviceSuballocator interface to handle offsets and memory pairs transparently, avoiding OS-level allocation failures when managing Vulkan buffers, as outlined in the Device Suballocator section.
Uses std::shared_ptr and std::weak_ptr to manage object hierarchies, ensuring parent-child relationships like Device and DeviceMemory are maintained correctly, preventing undefined behavior from early destruction.
Simplifies resource creation and management while staying close to the native Vulkan API, reducing boilerplate code without completely hiding low-level control, aligning with its stated philosophy.
The project is under heavy development with expected bugs and interface changes, making it unsuitable for production code, as explicitly warned in the README.
Adds abstraction layers that can incur performance costs relative to native Vulkan if not used with intended patterns, such as during resource tracking or struct copying, as noted in the high-performance design caveats.
Structs containing handles are not binary compatible with Vulkan, requiring data copying for API calls, which introduces overhead and complexity for integration with native Vulkan code.
