FrameGraph

FrameGraph simplifies prototyping on Vulkan and can be used as a base layer for the graphics engine. FrameGraph designed for maximum performance but not at the expense of usability. API developed as simple as possible, it hides all synchronizations, memory allocations and all this boilerplate code that is needed to get Vulkan work. Builtin validations together with Vulkan validation layers allow you to quickly find and fix errors.

Features

• multithreaded command buffer building and submission.
• simple API, hides memory allocation, host<->device transfers, synchronizations.
• shader debugging and profiling.
• supports RTX extensions.
• supports async compute and async transfer queues.
• all render tasks are stateless.

Used vulkan features and extensions:

• push constants
• dynamic buffer offset
• specialization constants
• VK_EXT_debug_utils
• VK_KHR_dedicated_allocation
• VK_KHR_sampler_mirror_clamp_to_edge
• VK_EXT_descriptor_indexing
• VK_NV_mesh_shader
• VK_NV_shading_rate_image
• VK_NV_ray_tracing
• VK_KHR_shader_clock
