From 4e4b5ccf148f3ca5b7d94dd111a4b89ee9422934 Mon Sep 17 00:00:00 2001 From: MichaelFisher1997 Date: Mon, 19 Jan 2026 08:02:43 +0000 Subject: [PATCH 01/49] refactor(rhi): decouple RHI into subsystems Extracts core RHI subsystems to address the God Object anti-pattern: - Created `src/engine/graphics/rhi_types.zig` to separate data types from interfaces - Created `src/engine/graphics/vulkan/` directory for subsystem implementations - Implemented `ResourceManager`: Handles Buffers, Textures, Shaders, and staging - Implemented `FrameManager`: Manages frame sync (fences, semaphores) and command buffers - Implemented `SwapchainPresenter`: Wraps swapchain creation and presentation - Implemented `DescriptorManager`: Manages descriptor pools, layouts, and sets - Refactored `VulkanContext` in `rhi_vulkan.zig` to coordinate these subsystems instead of implementing everything directly Fixes #190 --- src/engine/graphics/rhi.zig | 256 +- src/engine/graphics/rhi_types.zig | 227 ++ src/engine/graphics/rhi_vulkan.zig | 2604 ++++------------- .../graphics/vulkan/descriptor_manager.zig | 265 ++ src/engine/graphics/vulkan/frame_manager.zig | 180 ++ .../graphics/vulkan/resource_manager.zig | 690 +++++ .../graphics/vulkan/swapchain_presenter.zig | 96 + 7 files changed, 2131 insertions(+), 2187 deletions(-) create mode 100644 src/engine/graphics/rhi_types.zig create mode 100644 src/engine/graphics/vulkan/descriptor_manager.zig create mode 100644 src/engine/graphics/vulkan/frame_manager.zig create mode 100644 src/engine/graphics/vulkan/resource_manager.zig create mode 100644 src/engine/graphics/vulkan/swapchain_presenter.zig diff --git a/src/engine/graphics/rhi.zig b/src/engine/graphics/rhi.zig index 5e399a66..c98bc2a9 100644 --- a/src/engine/graphics/rhi.zig +++ b/src/engine/graphics/rhi.zig @@ -4,229 +4,39 @@ const Mat4 = @import("../math/mat4.zig").Mat4;
