How elliahu/hammock works

Hammock is a cross-platform C++23/Vulkan game-engine library. Its primary workflow is an application using the engine to create a window and Vulkan device, load scene assets, prepare GPU resources and graphics pipelines, and render through the engine’s rendering context. The README also documents UI, deferred physically based rendering, volumetric clouds, texture types, and image-based lighting/environment-map generation. The sampled code directly supports resource creation and environment-map generation; several runtime subsystem links are based on the documented capabilities and module boundaries, since their implementations were not sampled.
